Printing & Packaging Guide: Packaging Materials Guide

Selecting suitable packaging materials is one of the most important decisions during product development. Different materials provide different levels of strength, print quality, sustainability and cost efficiency. Consequently, understanding their characteristics helps businesses choose packaging that performs effectively throughout storage, transport and retail display.

Today, cardboard packaging remains one of the most versatile and environmentally responsible packaging solutions available. Nevertheless, not every board grade suits every application. Luxury products often require rigid board, whereas lightweight retail cartons may perform perfectly with folding boxboard or kraft card.

Depending on your industry, different packaging materials offer distinct advantages. Food businesses often prioritise food-safe board, while luxury brands typically select rigid board with decorative papers and premium finishes. Likewise, e-commerce companies generally choose corrugated packaging because it provides superior protection during transit.

Packaging Card GSM Guide -Packaging Guide

Understanding packaging card GSM is essential when specifying custom packaging. GSM stands for grams per square metre, representing the weight of paperboard. Although GSM does not directly measure thickness, it provides a useful indication of strength and suitability for different packaging applications.

Most importantly, as GSM increases, packaging generally becomes stronger and more rigid. However, choosing the highest GSM is not always the best option. Instead, businesses should balance product protection, manufacturing efficiency, shipping costs and premium appearance.

For example, cosmetic cartons frequently use 350–400gsm SBS board because it provides excellent print quality while maintaining structural integrity. Conversely, premium gift boxes usually incorporate thick greyboard wrapped with printed paper to create a luxurious appearance.

However, if you manufacture products for retail, food, cosmetics or gifting, our specialists can recommend the ideal board specification based on your product weight, transportation requirements and branding objectives. Additionally, our future Packaging Card GSM Guide will provide comprehensive comparisons, conversion charts and expert recommendations for every board grade.

Custom Packaging Guide for Modern Businesses

Today, custom packaging has become a powerful marketing tool rather than simply a protective container. Therefore, businesses increasingly invest in packaging that improves customer experience, strengthens brand recognition and supports sustainable manufacturing. Moreover, advances in printing technology now allow companies to create highly customised packaging for both short and large production runs.

Consequently, understanding packaging materials, structural design and commercial printing methods enables businesses to reduce waste, improve efficiency and deliver a more memorable customer experience.

Packaging Guide – Printing Methods Guide

Selecting the right printing method is just as important as choosing the correct packaging material. Different printing technologies produce different levels of colour accuracy, image sharpness, production speed and overall cost. Therefore, understanding how each process works allows businesses to achieve the ideal balance between quality, efficiency and budget.

Moreover, modern printing has evolved considerably over the last decade. Today, businesses can choose from digital printing for short runs, lithographic offset printing for premium retail packaging, flexographic printing for corrugated cartons and labels, as well as specialised UV and screen printing for decorative applications. Consequently, every packaging project should begin by selecting the printing process that best matches the product requirements.

Most Common Printing Methods Used in Packaging – Packaging Guide

Offset Lithographic Printing

Offset lithographic printing remains the preferred choice for premium folding cartons and luxury retail packaging because it delivers outstanding colour accuracy and sharp image reproduction. Furthermore, it supports complex artwork, fine typography and high-resolution photography. As production volumes increase, offset printing becomes increasingly cost-effective, making it ideal for medium and large manufacturing runs.

Digital Printing

Digital printing has transformed short-run packaging production. Since it requires no printing plates, businesses can produce prototypes, personalised packaging and seasonal campaigns much more quickly. Additionally, digital technology allows brands to test new packaging concepts before committing to large production quantities.

Flexographic Printing

Flexographic printing is widely used for corrugated packaging, shipping cartons, paper bags and labels. It combines high production speeds with durable inks, making it particularly suitable for industrial and e-commerce packaging applications.

Screen & UV Printing

For luxury packaging, screen printing and UV printing provide decorative possibilities that standard printing methods cannot always achieve. They produce vibrant colours, raised textures and premium visual effects that enhance the perceived value of the finished packaging.

Packaging Guide – Luxury Packaging Finishes Guide

Luxury packaging is more than an attractive outer box—it creates a memorable first impression that reflects the quality of your brand. While structural design protects the product, premium finishing techniques elevate packaging into an experience that customers remember long after the purchase. Consequently, many luxury brands invest in decorative finishes that communicate craftsmanship, exclusivity and attention to detail.

Whether you manufacture cosmetics, jewellery, premium food products, fashion accessories or corporate gifts, the right finishing combination can significantly improve perceived value. Furthermore, luxury finishes help products stand out on crowded retail shelves while reinforcing a premium brand image across every customer touchpoint.

Most Popular Luxury Packaging Finishes – Packaging Guide

Foil Stamping

Foil stamping remains one of the most recognised luxury finishing techniques. Available in gold, silver, rose gold, copper, holographic and many custom colours, foil instantly attracts attention while creating a sophisticated appearance. Moreover, foil is often combined with embossing to give logos and brand names additional depth.

Embossing & Debossing

Embossing raises selected artwork above the surface of the packaging, whereas debossing presses the design into the material. Both techniques create a tactile experience that customers naturally interact with. Consequently, these finishes are commonly used for luxury gift boxes, jewellery packaging and premium corporate presentation boxes.

Spot UV Coating

Spot UV applies a high-gloss coating to selected design elements while leaving the remaining surface matte. This contrast immediately draws attention to important branding elements such as logos, illustrations or product names. Additionally, raised Spot UV adds texture, creating an even more premium visual effect.

Soft-Touch & Anti-Scratch Lamination

Soft-touch lamination provides a luxurious velvet-like feel that customers immediately notice when holding the packaging. Anti-scratch lamination offers a similar premium appearance while improving resistance to fingerprints and surface marks. Therefore, both finishes are excellent choices for luxury retail packaging that requires durability as well as elegance.

Complete Box Styles Guide -Packaging Guide

Every successful packaging project begins with selecting the correct box style. Although artwork, materials and luxury finishes play an important role, the structural design of the box ultimately determines how well the product is protected, displayed and experienced by customers. Consequently, choosing the wrong box style can increase manufacturing costs, reduce protection during transport and negatively affect the overall customer experience.

Overall, the purpose of this Complete Box Styles Guide is to help businesses understand the most popular packaging structures used across the retail, e-commerce and luxury packaging industries. Furthermore, each style offers different advantages depending on the product, budget and intended use. Therefore, understanding these differences allows brands to make informed packaging decisions while improving both functionality and visual appeal.

Popular Packaging Box Styles – Packaging Guide

Straight Tuck End (STE)

The Straight Tuck End is one of the most widely used folding carton designs within the packaging industry. Both top and bottom flaps fold in the same direction, creating a clean appearance that is particularly suitable for premium retail products. Moreover, this style offers excellent print coverage because the front panel remains uninterrupted by visible locking tabs.

Moreover, straight tuck boxes are frequently used for cosmetics, skincare products, pharmaceuticals, electronics, confectionery and many other lightweight retail products.

Reverse Tuck End (RTE)

Reverse Tuck End boxes remain one of the most economical packaging styles because the top and bottom flaps fold in opposite directions. Consequently, they reduce board waste during production while remaining easy to assemble. This style is especially popular for cosmetic cartons, health products and consumer goods requiring quick manual packing.

Auto Lock Bottom Boxes

Products with greater weight require stronger structural support. Therefore, Auto Lock Bottom boxes automatically lock into position during assembly, providing exceptional strength without requiring additional tape. These boxes are commonly used for bottled products, candles, glass containers and premium food packaging.

Mailer Boxes

Mailer boxes have become increasingly popular with subscription services, direct-to-consumer brands and e-commerce retailers. Unlike standard folding cartons, mailer boxes feature interlocking flaps that create additional strength without requiring adhesive. As a result, they protect products during shipping while also delivering an impressive unboxing experience.

Furthermore, mailer boxes provide a large printable surface for branding, promotional messages and product information. Businesses often combine them with tissue paper, custom inserts and branded stickers to enhance customer satisfaction.

Rigid Boxes

Rigid boxes represent the highest level of premium packaging. Manufactured using thick greyboard wrapped with decorative paper, these boxes cannot be folded flat and therefore provide outstanding structural integrity. Luxury brands frequently choose rigid packaging for jewellery, watches, electronics, cosmetics, perfumes and corporate gifts because it communicates quality before customers even open the box.

Additionally, rigid boxes pair exceptionally well with decorative finishes such as foil stamping, embossing, magnetic closures, ribbon pulls and soft-touch lamination, making them the preferred choice for premium product presentation.

Sleeve Boxes

Sleeve boxes consist of two separate components: an inner tray that securely holds the product and an outer sleeve that slides over the tray. Although this design appears simple, it creates an elegant presentation that immediately enhances the perceived value of a product. Consequently, sleeve boxes are widely used for premium chocolates, cosmetics, electronics, promotional products and luxury gift packaging.

Moreover, sleeve boxes provide excellent branding opportunities because both the tray and sleeve can feature different colours, finishes and printed artwork. Many luxury brands also combine sleeve packaging with foil stamping, embossing or Spot UV to create a sophisticated unboxing experience.

Drawer (Slide-Out) Boxes

Drawer boxes, sometimes called slide-out boxes, operate similarly to a drawer opening from a cabinet. The rigid outer shell remains fixed while the inner tray slides smoothly outward using either a thumb notch or decorative ribbon pull. Therefore, this packaging style creates a premium opening experience that customers associate with luxury products.

Luxury cosmetics, watches, jewellery, electronics, mobile accessories and corporate gift sets frequently use drawer boxes because they combine excellent product protection with an unforgettable presentation. Additionally, EVA foam, cardboard inserts or moulded pulp inserts can be incorporated to hold products securely during transportation.

Magnetic Closure Boxes

Among all premium packaging solutions, magnetic closure boxes are considered one of the most luxurious. Hidden magnets inside the lid create a smooth closing mechanism while maintaining a clean exterior appearance. Consequently, these boxes are often selected for high-value retail products where presentation is just as important as protection.

In addition, luxury apparel brands, jewellery manufacturers, technology companies and premium gift retailers frequently choose magnetic rigid boxes because they create an exceptional first impression. Furthermore, decorative finishes such as soft-touch lamination, gold foil and embossed logos complement this structure perfectly.

Window Boxes

Window boxes include a transparent film or open die-cut section that allows customers to view the product before making a purchase. As a result, they improve consumer confidence while increasing shelf appeal. Food packaging, bakery products, confectionery, candles and cosmetics frequently use window packaging because product visibility supports purchasing decisions.

Additionally, if you require this style, explore our
Custom Window Boxes,
which can be manufactured in various sizes with recyclable window materials.

Display & Counter Display Boxes

Retail display boxes are specifically designed to present products directly on shop shelves or checkout counters. Unlike standard packaging, display boxes combine transportation and merchandising into one structure. Therefore, retailers can quickly place products on display without unpacking individual cartons.

Display packaging is particularly suitable for confectionery, cosmetics, stationery, promotional products and impulse-purchase items. Furthermore, vibrant printing and bold branding help maximise product visibility within busy retail environments.

Corrugated Shipping Boxes

When product protection becomes the highest priority, corrugated shipping boxes remain the preferred solution. Their fluted construction absorbs impact during transportation while providing excellent stacking strength. Consequently, e-commerce retailers and manufacturers rely on corrugated packaging for shipping products safely across the UK and internationally.

In addition, learn more about our
Corrugated Packaging Boxes,
manufactured for strength, durability and sustainable shipping.

How to Choose the Right Box Style – Packaging Guide

Selecting the correct packaging style depends upon several practical considerations. Although appearance remains important, businesses should first evaluate the product’s weight, dimensions, transportation requirements and target audience. Afterwards, decorative finishes and branding elements can be incorporated to create a complete packaging solution.

Packaging Artwork Preparation Guide – Packaging Guide

Designing attractive packaging is only the first step towards producing a high-quality printed box. Equally important is preparing the artwork correctly before it reaches the printing press. Even the most creative design can result in blurred images, incorrect colours, missing text or costly production delays if the artwork is not supplied in the correct format. Therefore, understanding artwork preparation is essential for designers, marketing teams and businesses ordering custom packaging.

Overall, this Packaging Artwork Preparation Guide explains the essential technical requirements for creating professional print-ready artwork. Moreover, by following these best practices, you can minimise production errors, reduce approval times and ensure your finished packaging looks exactly as intended.

Essential Elements of Print-Ready Artwork – Packaging Guide

Professional packaging artwork consists of far more than attractive graphics. Every file should include bleed, trim lines, safe areas, correctly embedded images, vector logos and production-ready colour settings. Consequently, designers should always prepare artwork according to commercial printing standards rather than screen display requirements.

Understanding Bleed, Trim Line and Safe Area

One of the most common mistakes in packaging artwork is misunderstanding bleed and safe areas. Bleed is the extra printed area extending beyond the finished trim size. During production, sheets are trimmed using industrial cutting equipment, and a small movement can occur. Therefore, extending background colours and images into the bleed prevents unwanted white edges from appearing.

Likewise, important information such as logos, product names, nutritional details and barcodes should remain inside the safe area. This precaution ensures that no critical design elements are accidentally removed during trimming.

CMYK vs RGB

Digital screens display colours using RGB (Red, Green and Blue), whereas commercial printing presses reproduce colours using CMYK (Cyan, Magenta, Yellow and Black). Consequently, artwork designed entirely in RGB may appear brighter on screen than in the final printed packaging.

Furthermore, to achieve consistent colour reproduction, packaging artwork should always be created in CMYK from the beginning of the design process. Furthermore, businesses with established brand colours may also specify Pantone colours to achieve greater colour consistency across multiple print runs.

Image Resolution

High-resolution images are essential for professional packaging. Although low-resolution graphics may appear acceptable on a computer monitor, they often become blurred or pixelated when printed. Therefore, all photographs and raster images should normally be supplied at a minimum resolution of 300 DPI at their final print size.

However, vector graphics such as logos and icons should be created in Adobe Illustrator or another vector application whenever possible. Unlike raster images, vector artwork can be enlarged without losing quality, making it ideal for commercial printing.

Fonts, Typography and Text Readability

Typography is one of the most overlooked aspects of packaging artwork. Nevertheless, it has a significant influence on readability, brand recognition and the overall appearance of your packaging. Customers should be able to identify the product name, brand, instructions and important information quickly, whether they are browsing on a retail shelf or opening an online order.

Furthermore, for commercial printing, fonts should either be converted to outlines or embedded correctly within the artwork file before submission. Otherwise, missing fonts may be substituted automatically during production, altering the layout and affecting the finished packaging. Furthermore, avoid using excessively thin typefaces for small text because they may lose clarity when printed.

Barcodes, QR Codes and Variable Data

Modern packaging often includes barcodes, QR codes, serial numbers or batch information. These elements must remain sharp and unobstructed to ensure they scan correctly throughout the supply chain. Therefore, barcodes should never be stretched, distorted or positioned across folds, glue flaps or cut lines.

Similarly, QR codes should be generated at a suitable resolution and tested before production begins. Many businesses now use QR codes to direct customers to user guides, promotional campaigns, product authentication pages or sustainability information.

Legal and Regulatory Information – Packaging Guide

Depending on the product and market, packaging may need to include mandatory information such as ingredients, nutritional values, safety warnings, recycling symbols, country of origin, manufacturer details or compliance marks. Consequently, artwork should always be reviewed carefully before approval to ensure all legal requirements have been met.

Most importantly, for food, cosmetics and pharmaceutical packaging, regulations may vary between industries and export markets. Therefore, confirming compliance before printing can prevent expensive reprints and unnecessary delays.

Common Packaging Artwork Mistakes – Packaging Guide

Even experienced designers occasionally overlook technical details that affect the final printed result. Fortunately, most problems can be avoided by carrying out a thorough pre-flight check before submitting artwork.

Packaging Artwork Pre-Flight Checklist

Before approving artwork for production, review every file carefully. A systematic quality check helps avoid unnecessary delays while ensuring consistent print quality across every production run.

Artwork Approval Process

Once artwork has been submitted, manufacturers typically carry out a pre-production inspection before sending a digital proof or press proof for approval. At this stage, every element should be reviewed carefully, including colours, spelling, dimensions, positioning and finishing instructions. After approval, production usually begins immediately, making late amendments significantly more expensive.

For this reason, businesses should appoint a single decision-maker to review proofs thoroughly before giving final approval. A structured approval process reduces the risk of errors while ensuring every production run meets brand standards.

Packaging Dielines & Structural Engineering Guide – Packaging Guide

Every custom packaging box begins long before artwork is printed or materials are selected. Behind every professionally manufactured carton is a carefully engineered structural layout known as a packaging dieline. Although customers only see the finished box, the dieline determines how the packaging folds, locks, protects the product and performs throughout manufacturing, shipping and retail display. Consequently, structural engineering is one of the most important stages in packaging development.

Whether you are producing a simple tuck-end carton, a luxury rigid gift box or a heavy-duty corrugated shipping box, the packaging structure must be designed with precision. A well-engineered dieline reduces production waste, improves assembly efficiency and ensures the finished packaging performs exactly as intended. Therefore, businesses should always consider structural design alongside branding and aesthetics rather than treating it as a separate stage.

Understanding the Main Components of a Dieline

Although dielines may appear complex initially, they are made up of several standard elements used throughout the packaging industry. Each line serves a specific manufacturing purpose and must be positioned accurately to ensure reliable production.

Why Structural Engineering Is So Important

Effective structural engineering does far more than determine the appearance of a package. It directly affects manufacturing efficiency, shipping performance, customer experience and production costs. Consequently, experienced packaging engineers evaluate numerous factors before approving a structural design.

• Product dimensions and weight.
• Material strength and board grade.
• Stacking requirements during transport.
• Protection against compression and impact.
• Ease of assembly on production lines.
• Retail shelf presentation.
• Unboxing experience.
• Storage efficiency.
• Shipping costs.
• Sustainability objectives.

For example, a luxury perfume box requires a completely different structural approach from an e-commerce mailer or a bakery carton. Therefore, every packaging solution should be engineered specifically for its intended application rather than using a generic template.

The Packaging Engineering Process

Professional packaging manufacturers follow a structured engineering workflow to ensure every box performs reliably during production and throughout its lifecycle. Although individual projects vary, most custom packaging developments follow the same sequence.

CAD Packaging Design & Structural Development

Modern packaging engineering begins with Computer-Aided Design (CAD). Instead of drawing packaging manually, structural designers create highly accurate digital dielines using specialist packaging software. This allows every panel, fold, locking tab and glue flap to be engineered with precision before any material is cut. Consequently, CAD design reduces development time while improving manufacturing accuracy.

CAD software also enables engineers to visualise how a flat sheet transforms into a finished package. Furthermore, structural adjustments can be made within minutes, allowing multiple design options to be evaluated before tooling is manufactured. This flexibility is particularly valuable for businesses developing new products or refining existing packaging.

Packaging Prototypes and White Samples

Before full-scale production begins, manufacturers usually produce a prototype, often referred to as a white sample or plain sample. This prototype is created without printed graphics, allowing the structural design to be evaluated independently from the artwork.

Furthermore, testing a prototype provides an opportunity to confirm that the product fits correctly, the box opens and closes smoothly, inserts hold the product securely and assembly can be completed efficiently. Moreover, identifying structural issues during prototyping is significantly less expensive than discovering them after production has started.

Packaging Inserts and Internal Protection – Packaging Guide

Many products require additional protection inside the outer box. Packaging inserts help prevent movement during transport while improving product presentation when customers open the package. Depending on the application, inserts may be manufactured from cardboard, corrugated board, moulded pulp, EVA foam or other protective materials.

Moreover, luxury packaging often incorporates precision-cut inserts that display products neatly while reinforcing a premium appearance. Similarly, fragile products benefit from custom-engineered inserts that distribute impact forces more evenly throughout the package.

Glue Systems and Locking Mechanisms

Not every packaging box requires adhesive during assembly. Many folding cartons include self-locking tabs, crash-lock bottoms or interlocking closures that improve packing speed while maintaining structural strength. Conversely, rigid boxes and certain premium packaging styles require carefully controlled adhesive application to achieve precise alignment and a flawless finish.

Selecting the correct locking mechanism depends upon the product weight, manufacturing process and intended customer experience. Therefore, structural engineers consider both performance and production efficiency during the design stage.

Structural Performance Testing

Professional packaging should perform reliably throughout storage, transportation and retail handling. Consequently, structural designs are frequently evaluated using a combination of physical testing and engineering calculations before mass production begins.

• Compression testing.
• Drop testing.
• Stacking performance evaluation.
• Transit simulation.
• Moisture resistance assessment.
• Assembly efficiency testing.

Above all, these evaluations help ensure the packaging protects the product while maintaining its appearance from the production line to the final customer.

Common Structural Design Mistakes

Even minor engineering errors can affect packaging performance. Fortunately, many issues can be avoided through careful planning, prototyping and quality assurance.

Packaging Dimensions & Measurement Guide – Packaging Guide

Accurate measurements are fundamental to successful packaging design and manufacturing. Even the highest-quality materials, premium printing and luxury finishes cannot compensate for incorrect dimensions. If a box is too small, the product may not fit safely. Conversely, if the box is unnecessarily large, businesses waste material, increase shipping costs and reduce storage efficiency. Therefore, understanding how packaging dimensions are measured is essential before ordering custom packaging.

Whether you require folding cartons, rigid boxes, corrugated shipping cartons or retail packaging, manufacturers calculate every dieline from the finished dimensions of the package. Consequently, providing precise measurements helps reduce development time, avoid production errors and ensure the finished packaging performs as expected.

The Standard Order of Packaging Dimensions

Across the global packaging industry, dimensions are almost always written in the same order:

Although this format appears straightforward, confusion often arises because different people measure from different orientations. Therefore, it is important to use consistent terminology throughout the design and manufacturing process.

Internal Dimensions vs External Dimensions

One of the most common misunderstandings when ordering packaging is the difference between internal and external measurements. Internal dimensions describe the usable space inside the finished box, whereas external dimensions include the thickness of the board and any structural components. Consequently, manufacturers generally request internal dimensions because these determine whether the product fits correctly.

How to Measure a Product for Custom Packaging

Before requesting a quotation, carefully measure the product itself rather than estimating the box size. Ideally, measurements should be taken using digital callipers or an accurate steel ruler. Additionally, consider any accessories, instruction manuals, protective inserts or internal packaging that will be placed inside the finished box.

1. Measure the longest side of the product.
2. Measure the shorter side.
3. Measure the overall height.
4. Add clearance for inserts or protective padding.
5. Confirm whether the product requires a tight or loose fit.
6. Provide measurements in millimetres whenever possible.

Allowing Space for Inserts and Protective Packaging

Many products require additional internal protection. Foam inserts, cardboard dividers, moulded pulp trays or paper cushioning all occupy valuable space inside the package. Therefore, these components should be considered during the initial design stage rather than added afterwards.

Luxury packaging often incorporates precision-engineered inserts that securely position the product while enhancing the customer experience. Likewise, e-commerce packaging frequently requires additional protective materials to minimise movement during transportation.

Packaging Tolerances and Manufacturing Accuracy

Although packaging manufacturers work to extremely high standards, every manufacturing process includes acceptable tolerances. These slight variations occur during printing, die-cutting, creasing, folding and gluing. Consequently, structural engineers always design packaging with realistic production tolerances rather than expecting every box to measure exactly the same.

Furthermore, the acceptable tolerance depends on several factors, including the packaging material, board thickness, box size, production equipment and finishing techniques. Therefore, businesses should avoid designing packaging with zero clearance, particularly when products fit tightly inside inserts or presentation boxes.

Packaging Size Standards

Most custom packaging is manufactured in millimetres because this provides the greatest level of accuracy. Nevertheless, businesses operating internationally may also use centimetres or inches depending on their market. Therefore, it is important to specify the unit of measurement whenever requesting quotations or approving technical drawings.

Choosing the Right Clearance

A package should never fit so tightly that the product becomes difficult to insert or remove. Equally, excessive empty space allows movement during transportation, increasing the risk of damage. Consequently, packaging engineers calculate an appropriate clearance based on the product dimensions, packaging material and any protective inserts used inside the box.

In addition, fragile products such as glass bottles, cosmetics and electronics generally require additional clearance to accommodate cushioning materials. Conversely, luxury presentation boxes often use precision-cut inserts to minimise movement while maintaining an elegant appearance.

Packaging Dimensions for Shipping

Shipping packaging requires a different approach from retail packaging. While retail cartons prioritise shelf appearance and branding, shipping cartons must withstand stacking, handling and transportation. Therefore, engineers often optimise external dimensions to maximise pallet efficiency, reduce courier costs and minimise unused shipping space.

Meanwhile, businesses shipping products through fulfilment centres should also consider dimensional weight calculations, pallet layouts and warehouse storage requirements during the packaging design process.

Frequently Asked Questions About Packaging Dimensions – Packaging Guide

Should I measure the product or the existing box?

Always measure the product itself whenever possible. Existing packaging may contain unnecessary empty space or additional protective materials that are not required for your new packaging design.

Do manufacturers need internal or external dimensions?

In most cases, manufacturers prefer internal dimensions because these determine how well the product fits inside the finished packaging. External dimensions are then calculated during the engineering stage.

How much extra space should I leave?

The required clearance depends on the product, board thickness, inserts and transportation requirements. Packaging engineers normally recommend the appropriate tolerance after reviewing the product specification.

Packaging Materials Guide: Choosing the Right Material for Every Product

The success of any packaging project depends not only on its design but also on selecting the most suitable material. Even an outstanding structural design cannot perform effectively if the wrong board or paper is used. Consequently, understanding packaging materials is one of the most important steps when developing custom packaging for retail, e-commerce, food, cosmetics, electronics or luxury products.

Moreover, every packaging material offers different levels of strength, print quality, sustainability, moisture resistance and cost. Therefore, manufacturers evaluate several factors before recommending a board grade, including the product weight, transportation method, storage conditions, printing requirements and customer expectations.

This comprehensive Packaging Materials Guide explains the most widely used materials in commercial printing and packaging manufacturing. Whether you are designing folding cartons, rigid boxes, corrugated packaging or luxury presentation boxes, choosing the correct substrate ensures excellent print quality, reliable protection and efficient production.

Paperboard vs Cardboard – What’s the Difference?

Many people use the terms paperboard and cardboard interchangeably. However, within the packaging industry they describe different materials with distinct applications.

Paperboard is a smooth, high-quality material primarily used for folding cartons and premium printed packaging. It offers excellent printability, making it ideal for cosmetics, pharmaceuticals, food products and retail packaging.

However, cardboard generally refers to heavier packaging materials designed to provide greater structural strength. Corrugated cardboard, rigid greyboard and heavy-duty packaging boards are commonly used where durability is more important than premium print quality.

Solid Bleached Sulphate (SBS)

Solid Bleached Sulphate, commonly known as SBS, is one of the highest-quality paperboards available. Manufactured entirely from virgin wood pulp, it features an exceptionally smooth white surface that delivers outstanding print quality. Consequently, SBS is frequently chosen for luxury packaging where colour accuracy and fine detail are essential.

Because SBS provides excellent stiffness, cleanliness and food safety, it is widely used for premium cosmetics, pharmaceuticals, confectionery, skincare products and luxury retail packaging. Furthermore, it accepts speciality finishes such as soft-touch lamination, embossing, foil stamping and Spot UV exceptionally well.

Folding Box Board (FBB)

Folding Box Board, often abbreviated as FBB, combines multiple fibre layers to create a lightweight yet rigid packaging material. Typically manufactured with virgin fibres on the outer layers and mechanical pulp in the centre, FBB provides an excellent balance between strength, printability and cost.

Many consumer brands choose FBB because it offers premium visual quality while remaining lighter than some alternative boards. As a result, it helps reduce transportation costs without compromising structural performance.

Moreover, FBB is commonly used for:

• Cosmetic packaging.
• Healthcare products.
• Luxury food packaging.
• Retail cartons.
• Pharmaceutical boxes.
• Gift packaging.

Duplex Board

Duplex board features a white coated printing surface on one side with a grey or cream reverse side. It provides a practical combination of print quality and affordability, making it one of the most widely used materials for commercial packaging.

In many cases, many retail cartons, consumer products and promotional packaging solutions use duplex board because it offers reliable print performance while remaining economical for medium and high-volume production.

Kraft Board

Kraft board has become one of the fastest-growing packaging materials due to its natural appearance, excellent strength and environmental benefits. Manufactured using unbleached wood pulp, kraft board retains its characteristic brown colour while maintaining impressive tear resistance and durability. Consequently, it has become the preferred material for brands promoting sustainability and eco-conscious packaging.

Furthermore, besides its attractive natural appearance, kraft board performs exceptionally well for custom printing, embossing and simple foil applications. Many organic food producers, artisan brands, cosmetics companies and e-commerce retailers choose kraft packaging because it communicates authenticity and environmental responsibility.

Greyboard

Greyboard is a dense recycled board manufactured from compressed paper fibres. Although it is not normally used for direct printing, it provides exceptional rigidity and structural strength. Therefore, greyboard is widely used as the core material inside luxury rigid boxes, presentation cases and premium gift packaging.

During production, decorative printed paper is laminated onto the greyboard to create an elegant exterior while maintaining excellent structural integrity. This manufacturing method allows businesses to combine premium branding with outstanding durability.

Corrugated Board

Corrugated board is specifically engineered for strength and product protection. Unlike paperboard, corrugated packaging contains one or more fluted layers positioned between flat liner boards. These flutes absorb impact while increasing compression strength, making corrugated packaging ideal for transportation and e-commerce.

However, depending on the application, different flute profiles are selected to balance strength, cushioning and printability. Consequently, packaging engineers choose flute types according to product weight, stacking requirements and shipping conditions.

Virgin Fibre vs Recycled Fibre

Packaging boards are manufactured using either virgin fibres, recycled fibres or a combination of both. Virgin fibre boards generally provide brighter surfaces, greater consistency and superior print quality. Conversely, recycled fibre boards offer excellent environmental benefits while reducing raw material consumption.

Today, many manufacturers combine both fibre types to achieve an effective balance between sustainability, print performance and structural strength.

Coated and Uncoated Boards

The surface finish of a packaging board has a direct influence on print quality and appearance. Coated boards provide smoother surfaces that reproduce vibrant colours, detailed graphics and luxury finishes more effectively. Uncoated boards create a more natural appearance and are often selected for environmentally focused brands.

Food-Safe and Barrier-Coated Materials

Packaging used for food products must satisfy additional performance requirements beyond appearance alone. Depending on the application, boards may require moisture resistance, grease resistance or specialised barrier coatings that help protect food quality while maintaining structural integrity.

Similarly, many modern food packaging solutions now utilise recyclable water-based barrier coatings as an alternative to traditional plastic laminations. Consequently, businesses can improve sustainability while continuing to meet demanding performance standards.

Choosing the Best Material for Your Industry – Packaging Guide

Sustainable Packaging Guide: Eco-Friendly Packaging Solutions for Modern Businesses

Sustainability has become one of the most influential factors in modern packaging design. Businesses are no longer focused solely on protecting products or creating attractive branding. Instead, many organisations are actively seeking packaging solutions that reduce environmental impact while maintaining excellent quality, durability and customer appeal. Consequently, sustainable packaging has become an essential investment for manufacturers, retailers and e-commerce businesses throughout the UK.

Although, choosing environmentally responsible packaging does not necessarily mean compromising on strength or appearance. Advances in paperboard technology, recyclable coatings, water-based inks and renewable materials now enable businesses to manufacture premium packaging that meets both commercial and environmental objectives. Therefore, sustainable packaging should be viewed as a long-term strategy that benefits businesses, customers and the environment alike.

Why Sustainable Packaging Matters – Packaging Guide

Consumer expectations have changed significantly over the past decade. Many customers now actively support brands that demonstrate genuine environmental responsibility. As a result, businesses adopting sustainable packaging often strengthen their brand reputation while meeting the expectations of retailers, distributors and environmentally conscious consumers.

In addition to improving public perception, sustainable packaging can also reduce material consumption, optimise shipping efficiency and minimise long-term operational costs. Consequently, sustainability frequently delivers both environmental and commercial benefits.

Characteristics of Sustainable Packaging

A genuinely sustainable packaging solution should balance environmental responsibility with practical performance. While different industries have different requirements, several characteristics are consistently recognised as indicators of sustainable packaging.

• Manufactured using responsibly sourced materials.
• Designed for recyclability.
• Uses renewable or recycled fibres where appropriate.
• Minimises unnecessary material usage.
• Optimises transportation efficiency.
• Supports reuse where practical.
• Uses environmentally responsible inks and coatings.
• Maintains excellent product protection.

Recyclable Packaging Materials

Paperboard and corrugated packaging remain among the most widely recycled packaging materials available today. When designed appropriately, folding cartons, corrugated boxes and rigid paper-based packaging can often be collected through existing recycling systems, making them attractive choices for environmentally conscious brands.

However, recyclability depends upon the complete packaging construction. Heavy plastic laminations, mixed-material structures and certain speciality coatings may affect recycling performance. Therefore, packaging should always be engineered with its end-of-life disposal in mind.

The Role of FSC® Certification

Many businesses choose packaging manufactured from materials sourced through responsibly managed forests. Certification systems such as the Forest Stewardship Council (FSC®) provide assurance that certified materials originate from responsibly managed forest resources and controlled supply chains.

Although certification requirements vary depending on the product and manufacturer, many retailers and international brands increasingly request responsibly sourced paper-based packaging as part of their procurement standards.

Reducing Packaging Waste Through Better Design

Sustainability begins during the design stage rather than after production. Structural engineers often reduce environmental impact by optimising box dimensions, eliminating unnecessary components and selecting materials that provide adequate protection using less fibre. Consequently, intelligent packaging design can lower both material consumption and transportation costs without reducing performance.

Supporting the Circular Economy Through Packaging

Modern packaging design increasingly follows the principles of the circular economy. Rather than creating packaging that is used once and discarded, businesses are encouraged to design materials that remain in circulation for as long as possible through reuse, recycling and responsible material recovery. Consequently, many packaging manufacturers now focus on reducing waste while extending the useful life of packaging materials.

Paper-based packaging naturally supports many circular economy objectives because high-quality fibre can often be recovered and reused multiple times. Furthermore, designing packaging with simple material combinations makes recycling easier and improves resource efficiency.

Compostable, Biodegradable and Recyclable Packaging

These three terms are often confused, although they describe different environmental characteristics. Recyclable packaging is designed to be collected, processed and manufactured into new products through established recycling systems. Compostable packaging is designed to break down under specific composting conditions, while biodegradable materials degrade naturally over time under suitable environmental conditions. Therefore, businesses should understand these differences before selecting packaging materials or making environmental claims.

Reducing Plastic Through Smarter Packaging Design

Many businesses are actively replacing unnecessary plastic components with paper-based alternatives wherever product protection allows. For example, paper inserts, moulded pulp trays and recyclable paper cushioning can often replace plastic trays or foam inserts in many retail packaging applications. Similarly, water-based coatings may provide an alternative to certain plastic laminations for some packaging requirements.

However, material selection should always balance environmental considerations with product protection. Packaging that fails to protect the product can create unnecessary waste if damaged goods require replacement.

Lightweight Packaging and Carbon Reduction

Reducing package weight can lower transportation requirements and improve logistics efficiency. Structural engineers often achieve this by optimising box dimensions, selecting appropriate board grades and eliminating unnecessary components without compromising packaging performance.

Smaller, lighter packages may also improve warehouse utilisation, pallet efficiency and distribution costs. Consequently, lightweight packaging supports both operational efficiency and broader sustainability objectives.

Sustainable Luxury Packaging Guide

Luxury packaging and sustainability are no longer mutually exclusive. Premium rigid boxes, presentation packaging and gift boxes can now be manufactured using responsibly sourced paperboard, recycled greyboard, recyclable wraps and environmentally considerate finishing techniques. As a result, brands can create sophisticated packaging experiences while supporting responsible material choices.

Moreover, when specifying decorative finishes, businesses should also consider the recyclability of the complete package. Early collaboration between designers and manufacturers often produces attractive packaging that balances premium aesthetics with environmental considerations.

UK Packaging Requirements and Producer Responsibility

Businesses supplying packaging within the UK should remain aware of evolving packaging legislation and producer responsibility obligations. Requirements may vary depending on business size, packaging volumes and applicable regulations. Therefore, companies should review current government guidance and seek professional advice where necessary to ensure compliance with relevant environmental obligations.

Common Sustainability Misconceptions – Packaging Guide

Printing & Packaging Guide: Manufacturing Process From Concept to Finished Packaging

Every successful packaging project begins long before the first sheet of paperboard enters a printing press. Professional packaging manufacturing follows a carefully planned process that combines structural engineering, graphic design, material selection, precision printing and quality control to produce packaging that protects products while strengthening brand identity.

Whether you require folding cartons, rigid boxes, corrugated shipping cartons or luxury presentation packaging, every stage of production influences the appearance, durability and overall performance of the finished package. Consequently, understanding the packaging manufacturing process helps businesses make informed decisions, avoid costly mistakes and achieve consistent production quality.

Although individual projects vary depending on complexity, most custom packaging follows a similar production workflow. Each stage builds upon the previous one, ensuring the final product satisfies technical requirements, branding objectives and customer expectations.

Step 1: Consultation and Project Planning

Every custom packaging project begins with understanding the product, target market and branding requirements. During the consultation stage, packaging specialists gather technical information such as product dimensions, weight, storage conditions, shipping requirements, desired packaging style and printing specifications. This information forms the foundation of the entire manufacturing process.

In addition, businesses should also discuss expected order quantities, required delivery schedules, sustainability objectives and budget considerations at this stage. Early planning enables manufacturers to recommend suitable materials, optimise production methods and identify opportunities to improve cost efficiency without compromising quality.

Step 2: Structural Engineering and Dieline Development

Once the project requirements have been confirmed, structural designers create the packaging engineering drawings. Using specialist CAD software, they develop accurate dielines that define every cut, crease, locking tab and glue flap required for production.

However, engineers also verify that the packaging provides adequate product protection while remaining efficient to manufacture. If necessary, prototypes are produced to confirm product fit, structural strength and assembly performance before mass production begins.

Step 3: Graphic Design and Artwork Preparation

After the structural design has been approved, designers prepare the production artwork. Logos, product information, regulatory text, barcodes and marketing graphics are positioned precisely within the approved dieline. Colour accuracy, bleed areas, safe margins and image resolution are carefully reviewed before files proceed to pre-press.

Above all, well-prepared artwork significantly reduces production delays while ensuring consistent printing throughout the manufacturing process.

Step 4: Selecting the Right Packaging Material

Material selection influences both the appearance and structural performance of the finished packaging. Depending on the application, manufacturers may recommend SBS, Folding Box Board, duplex board, kraft board, greyboard or corrugated fibreboard. Each material offers different levels of print quality, rigidity, sustainability and product protection.

Luxury packaging often combines several materials, including rigid greyboard cores, decorative wrapping papers, foam inserts and speciality finishes to create a premium customer experience.

Step 5: Prototype and Sample Approval

Before full production begins, manufacturers often prepare physical samples or digital mock-ups for customer approval. This allows businesses to verify dimensions, colours, structural performance and finishing details before committing to large production quantities.

However, sampling is particularly valuable for premium packaging, product launches and complex structural designs because adjustments can be made before mass manufacturing starts. Once approved, the sample becomes the production reference for the remaining stages of manufacturing.

Step 6: Printing the Packaging

Once the packaging design, materials and artwork have been approved, production moves into the printing stage. The printing method is selected according to the order quantity, board type, colour requirements and finishing specifications. Modern printing presses reproduce logos, images, text and brand colours with exceptional consistency, ensuring every package reflects the desired brand identity.

By comparison, for premium retail packaging, colour accuracy is particularly important. Manufacturers therefore calibrate equipment, monitor colour density and verify printed sheets throughout production. This helps maintain consistency from the first sheet to the final carton.

Step 7: Applying Luxury Finishes

After printing, optional finishing techniques are applied to enhance both appearance and durability. Luxury finishes help products stand out on retail shelves while reinforcing the premium quality of a brand.

On the other hand, depending on the project, manufacturers may apply matt or gloss lamination, soft-touch coatings, Spot UV, embossing, debossing or foil stamping. These processes create visual impact while also protecting printed surfaces from wear during handling and transportation.

Step 8: Die Cutting, Creasing and Window Patching

Following printing and finishing, large printed sheets move to the die-cutting stage. Precision steel-rule dies cut the outer shape of the packaging while simultaneously creating fold lines, locking tabs and glue flaps. This process ensures every carton is manufactured to identical dimensions.

Nevertheless, where required, manufacturers may also apply window patching, perforations, tear strips or other structural features before the packaging progresses to assembly.

Step 9: Folding and Gluing

The die-cut blanks are transferred to automated folder-gluer machines where they are folded along the pre-creased lines and securely bonded using industrial adhesives. High-speed equipment produces consistent, accurately assembled cartons ready for packing or flat delivery.

Nevertheless, luxury rigid boxes follow a different manufacturing process, with experienced operators assembling each component individually to achieve the highest level of precision and presentation.

Step 10: Quality Inspection

Quality control is integrated throughout the manufacturing process rather than being limited to the final stage. Operators monitor colour consistency, registration, cutting accuracy, glue strength and structural performance at multiple checkpoints to ensure every batch meets production standards.

Ultimately, any packaging that fails to satisfy quality requirements is removed before dispatch. This systematic approach helps maintain consistency across the entire production run.

Step 11: Packing, Shipping and Delivery

Once approved, the finished packaging is counted, packed and prepared for shipment. Packaging may be supplied flat-packed for efficient storage or assembled where project requirements demand. Careful packing protects cartons during transportation while helping businesses receive production in excellent condition.

Above all, reliable logistics planning also ensures packaging arrives according to production schedules, allowing businesses to coordinate product launches, seasonal campaigns and inventory management more effectively.

Common Manufacturing Mistakes to Avoid – Packaging Guide

• Submitting low-resolution artwork.
• Providing incorrect product dimensions.
• Selecting an unsuitable board grade.
• Approving artwork without proofreading.
• Ignoring production tolerances.
• Leaving insufficient time for sampling.
• Choosing finishes that do not suit the intended application.

Packaging Guide: Final Professional Tips

Above all, choose packaging that matches your product rather than following short-term trends. Similarly, select materials that support both protection and sustainability. Meanwhile, ensure every box style works efficiently during packing and shipping. Moreover, test prototypes before approving mass production. For example, a small structural adjustment can improve strength without increasing material costs. In contrast, ignoring prototype testing often leads to expensive revisions. Even so, premium packaging should remain practical for everyday use. Afterwards, review every printed proof carefully before production begins. Consequently, you reduce errors and improve production efficiency. Overall, careful planning results in better packaging, stronger branding and greater customer satisfaction.

Why This Packaging Guide Matters

Packaging continues to evolve because consumer expectations, environmental legislation and printing technology change every year. Therefore, businesses that understand the complete packaging process often reduce production costs while improving product presentation. Furthermore, well-designed packaging protects products, supports logistics and increases customer confidence.

Instead of viewing packaging as a simple box, successful companies treat it as an investment in branding, customer experience and long-term business growth. Consequently, this Packaging Guide brings together every major topic required to make informed packaging decisions from concept through to manufacturing.
