Packaging Inserts Explained, Foam, Pulp, Fabric and Custom Tray Options

 

The box gets the attention. The insert earns the trust.

When a customer opens a package and finds the product sitting perfectly, held in place, presented with intention, surrounded by material that feels considered, that moment does more for your brand than almost any other touchpoint in the customer journey.

Custom packaging inserts are one of the most underutilised tools in a brand's packaging strategy. They are often treated as an afterthought,  something to stop the product from moving in transit. But the best brands understand that an insert is a presentation decision, not just a protection decision.

In this guide, we break down every major insert type available, foam, pulp, fabric, and custom trays, explain the differences, and help you understand which option is right for your product, your brand, and your budget.

What Are Custom Packaging Inserts?

 

A packaging insert is any internal structure placed inside a box to hold, protect, present, or organise a product. Inserts can be functional, decorative, or both, and in premium packaging, they are almost always both.

The right insert does three things simultaneously:

 

• Protects the product during transit and handling

 

• Presents the product in a way that elevates the unboxing experience

 

• Communicates brand values through material choice, finish, and craftsmanship

 

Custom packaging inserts are designed and manufactured specifically for a product, shaped, sized, and finished to fit the exact dimensions and aesthetic of the brand's packaging system.

 

Why Inserts Matter More Than Most Brands Realise

 

Most brands spend significant time choosing the right box structure and finish. Far fewer apply the same rigour to what goes inside.

This is a missed opportunity.

Research consistently shows that the unboxing experience has a direct impact on customer perception, repeat purchase behaviour, and social sharing. A product that arrives loose inside a box, even a beautifully printed one, signals carelessness. A product that arrives seated in a precisely cut foam cavity or a fabric-lined tray signals that the brand thought about every detail. 

For luxury brands, high-value products, gifting occasions, and DTC businesses where the box is the first physical touchpoint, inserts are not optional. They are essential.

The 2025 luxury packaging design landscape confirms this shift, brands are increasingly investing in layered interior structures, tactile insert materials, and precision-fit cavities as a primary driver of the unboxing experience, not a secondary consideration.

 

The Main Types of Custom Packaging Inserts

 

1. Foam Inserts

 

Foam is the most versatile insert material available. It can be cut, shaped, layered, and finished in more ways than any other insert type, making it suitable for everything from precision instrument packaging to luxury cosmetics. 

 

Types of foam used in packaging inserts:

 

EVA Foam (Ethylene Vinyl Acetate) EVA foam is one of the most widely used materials for custom packaging inserts. It is soft, lightweight, and highly customisable, available in a wide range of colours and densities. EVA foam provides excellent cushioning for delicate items and can be die-cut or CNC-routed into precise shapes. It is a popular choice for cosmetics, electronics accessories, and jewellery packaging. 

 

PE Foam (Polyethylene) PE foam is a firmer, more resilient option that offers strong shock absorption. It is commonly used for heavier or more fragile products that require structural support as well as cushioning. PE foam is durable, moisture-resistant, and available in multiple densities to match specific product weight and fragility requirements. 

 

PU Foam (Polyurethane) PU foam is the premium end of the foam insert spectrum. It is softer and more tactile than EVA or PE foam, with a fine cell structure that gives it a high-end feel. PU foam is often used in luxury watch boxes, high-end cosmetics, and premium gift packaging where the insert itself needs to feel as refined as the product it holds. 

 

Sponge Foam Sponge foam is a softer, more compressible option used primarily for light products where cushioning is needed but structural rigidity is not. It is often used as a base layer beneath a fabric-wrapped insert.

 

Key advantages of foam inserts:

• Highly customisable shape and cavity design
• Available in a wide range of colours and densities
• Excellent shock absorption and product protection
• Can be wrapped in fabric for a premium finish
• Suitable for complex or irregular product shapes

 

Best for: Jewellery, watches, cosmetics, electronics accessories, fragrance, medical devices, precision instruments.

 

2. Molded Pulp Inserts

 

Molded pulp inserts are made from recycled paper fibres that are formed into shape using a moulding process. They are one of the most sustainable insert options available, and increasingly, one of the most desirable for brands that want to communicate environmental responsibility without compromising on presentation.

Pulp inserts have evolved significantly. Early versions were associated with egg cartons and industrial packaging. Today, fine-cell molded pulp inserts are used by some of the world's most recognised luxury brands, with smooth surfaces, precise cavities, and a natural aesthetic that aligns with the growing consumer preference for sustainable packaging. 

 

Types of molded pulp:

 

Thick Wall Pulp The most common type, used for general product protection. Has a rougher surface texture and is best suited for functional rather than premium applications.

 

Thin Wall Pulp Produced using a more refined moulding process, thin wall pulp has a smoother surface and tighter tolerances. It is suitable for mid-range to premium packaging applications.

 

Fine Cell / Smooth Molded Pulp The premium tier of molded pulp. Fine cell pulp has a surface quality close to paper, smooth, consistent, and capable of holding fine detail. It is used in high-end cosmetics, electronics, and luxury gifting packaging.

 

Key advantages of molded pulp inserts:

• Made from recycled or sustainably sourced fibres
• Biodegradable and compostable
• Strong structural support for medium to heavy products
• Natural aesthetic that communicates sustainability
• Increasingly compatible with luxury brand positioning

 

Best for: Cosmetics, skincare, electronics, sustainable gifting, food and beverage gifting, brands with active sustainability commitments.

 

3. Fabric-Lined and Fabric-Wrapped Inserts

 

Fabric inserts are not a standalone insert type, they are a finish applied to a foam or rigid base. A foam insert wrapped in velvet, satin, or microfibre transforms a functional cavity into a presentation surface that communicates luxury at the highest level. 

Fabric-lined inserts are the standard in fine jewellery, luxury watches, high-end cosmetics, and premium gifting. The fabric choice, colour, and texture are all brand decisions, and each one contributes to the overall perception of the product inside.

 

Common fabric options:

 

Velvet The most recognised luxury insert fabric. Velvet has a deep, rich texture that photographs exceptionally well and feels premium to the touch. It is available in a wide range of colours and is the standard choice for jewellery and watch packaging.

 

Satin Satin offers a smooth, lustrous surface with a lighter, more delicate feel than velvet. It is commonly used in cosmetics packaging, lingerie gifting, and premium accessories.

 

Microfibre Microfibre is a modern, versatile fabric option that is soft, durable, and available in a wide range of colours and textures. It is increasingly used as a contemporary alternative to velvet in brands that want a less traditional luxury aesthetic.

 

Linen and Cotton Natural fabric options that communicate an organic, artisanal brand positioning. Used in sustainable luxury, artisan food gifting, and lifestyle brands.

 

Key advantages of fabric-lined inserts:

• Highest perceived value of any insert type
• Fully customisable in colour, texture, and material
• Elevates the unboxing experience significantly
• Protects product surfaces from scratching
• Photographs and films exceptionally well for social content 

 

Best for: Fine jewellery, luxury watches, high-end cosmetics, premium accessories, wedding and occasion gifting.

 

4. Custom Rigid Trays and Cardboard Inserts

 

Rigid trays and cardboard inserts are structural inserts made from greyboard, chipboard, or rigid card, often wrapped in paper, fabric, or specialty materials. They are the most versatile insert option in terms of structural configuration, allowing for multi-compartment layouts, tiered presentations, and complex product arrangements.

 

Types of rigid tray inserts:

 

Greyboard Trays Made from the same material used in rigid box construction, greyboard trays are strong, precise, and highly customisable. They can be wrapped in any material, paper, fabric, or specialty finishes, and configured into any compartment layout required.

 

Chipboard Dividers and Platforms Used to separate multiple products within a single box, or to create a raised platform effect that presents a hero product at a specific height. Common in multi-product gift sets, cosmetics collections, and subscription boxes.

 

Vacuum-Formed Plastic Trays Vacuum-formed trays are made from thin plastic sheet formed over a mould. They offer precise product cavities, are lightweight, and are cost-effective for high-volume production. They are commonly used in cosmetics, electronics, and food packaging, though they are less aligned with premium sustainability positioning.

 

Paper Pulp Trays (see Molded Pulp above)

 

Key advantages of rigid tray inserts:

• Precise multi-compartment configurations
• Strong structural support for heavy or multiple products
• Fully customisable wrap and finish options
• Compatible with all box structures, rigid, foldable, magnetic closure
• Cost-effective at scale 

 

Best for: Multi-product gift sets, cosmetics collections, subscription boxes, electronics, food and beverage gifting, corporate gifting.

 

How to Choose the Right Insert for Your Product

 

Choosing the right insert comes down to four key factors:

 

1. Product Type and Fragility

 

Fragile or high-value products, jewellery, watches, glass bottles, electronics, require inserts with strong cushioning and precise cavity fit. Foam inserts (EVA, PU) or fabric-lined foam are typically the best choice. For heavier products, PE foam or rigid trays provide the structural support needed.

 

2. Brand Positioning

 

Your insert material communicates your brand values before the customer even looks at the product. Velvet-lined foam says luxury. Smooth molded pulp says sustainable luxury. A rigid greyboard tray wrapped in textured paper says premium and considered. Match your insert material to the story your brand is telling.

 

3. Sustainability Goals

 

If your brand has active sustainability commitments, or if your customer base expects it, molded pulp and paper-based inserts are the strongest choice. They are biodegradable, made from recycled fibres, and increasingly available at a quality level that competes with foam and fabric options.

 

4. Budget and Volume

 

Insert costs vary significantly by material and complexity. Foam inserts are generally cost-effective at most volumes. Fabric-lined inserts carry a higher unit cost but deliver a disproportionate increase in perceived value. Molded pulp inserts can be cost-effective at higher volumes once tooling costs are absorbed. Discuss your volume and budget with your manufacturer early, the right insert at the right price point is always achievable with the right partner.

The Insert Is the Detail That Defines the Experience

 

A great box opens the door. A great insert closes the sale.

When a customer lifts the lid and finds their product seated perfectly, held in place by a material that was chosen with intention, they don't just feel satisfied. They feel that the brand cares. And that feeling is what drives repeat purchases, social sharing, and long-term loyalty. 

Custom packaging inserts are one of the highest-return investments a brand can make in its packaging system. The cost per unit is modest. The impact on customer perception is significant.

If you're building a packaging system and haven't yet thought carefully about what goes inside the box, now is the time.
