When brands compare molded pulp vs EVA vs foam, the real question is how to balance sustainable packaging materials, product protection, cost, and a luxury unboxing experience.
For premium packaging—whether it’s wine boxes, perfume packaging, cosmetic gift sets, or high-end electronics—the packaging insert inside the rigid box is just as important as the exterior.
A well-engineered insert should:
- Protect the product during shipping, storage, and display
- Support eco-conscious or eco friendly packaging inserts goals
- Enhance the perceived value as true luxury packaging inserts
In this guide we compare five commonly used insert options for custom rigid box inserts:
- Molded pulp inserts
- EVA inserts for packaging
- EPE foam inserts (pearl cotton)
- Sponge foam inserts (PU foam)
- Cardboard paper inserts / dividers
By the end, you will know which solution is the most sustainable and which is best suited to your next luxury packaging project.
What Is Molded Pulp?
Molded pulp inserts are eco-friendly packaging solutions made from natural, fiber-based materials such as:
- Recycled paper and cardboard
- Bamboo fiber
- Sugarcane bagasse
- Other plant-based molded fiber pulp
Sustainability Benefits of Molded Pulp Inserts
- Biodegradable packaging insert with minimal long-term waste
- Recyclable molded pulp tray in standard paper recycling streams
- Compostable under industrial or home-composting conditions
- Made from renewable resources
- Lower overall carbon footprint than plastic-based materials
Common Packaging Applications
Brands often weigh molded pulp vs foam when they want both protection and sustainability, especially for:
- Eco packaging for cosmetics and skincare sets
- Premium wine and spirit bottle packaging
- Natural or organic lifestyle products
- Electronics and accessories with sustainable branding

What Is EVA?
EVA inserts for packaging are made from Ethylene Vinyl Acetate, a soft, flexible, and impact-absorbing material commonly used in premium packaging inserts. EVA is especially popular in luxury projects that require a very clean, precise look and high-end presentation.
Benefits of EVA Inserts
- Excellent shock absorption for fragile products
- Smooth and highly premium appearance
- Perfect for precision-cut custom rigid box inserts
- Can be flocked or fabric-wrapped for even more luxury
- Widely used as perfume box inserts EVA for glass bottles and sets
Limitations of EVA
- Not biodegradable or compostable
- Recyclability is limited and depends on local facilities
- Less suitable for brands focused primarily on sustainable packaging materials
What Are EPE Foam and Sponge Foam?
In packaging, “foam insert” is an umbrella term. The two most commonly used foams in luxury and protective packaging are EPE foam (Expanded Polyethylene, also called pearl cotton) and sponge foam (PU sponge). Each behaves differently in terms of cushioning, density, appearance, and sustainability.
EPE Foam (Expanded Polyethylene)
EPE foam is a lightweight, semi-rigid closed-cell foam with strong shock absorption and moisture resistance. It is widely used in foam packaging inserts for fragile or heavy products.
- Excellent shock absorption and cushioning
- Lightweight, reducing overall shipping weight
- More rigid than sponge foam; keeps its shape well
- Moisture-resistant and durable
- Cost-effective for protective and logistics-focused packaging
Limitations of EPE Foam
- Not biodegradable
- Recycling options are limited by region
- Less premium-looking than EVA or flocked inserts
Sponge Foam (PU Foam)
Sponge foam (polyurethane) is a soft, flexible, open-cell material frequently found in cosmetic sets, gift boxes, and apparel accessories where a gentle, compressible insert is preferred.
- Softer touch than EPE foam
- Suitable for lightweight items
- Great for cosmetics, beauty tools, and small accessories
- Easy to die-cut into custom shapes
- More flexible and compressible than EPE
Limitations of Sponge Foam
- Lower shock resistance compared with EPE foam or EVA
- Poor moisture resistance
- Not eco-friendly; difficult to recycle
- Less durable in long-term or heavy-duty use
What Is Cardboard Paper Insert?
Cardboard paper inserts—also known as paper dividers or cardboard paper trays—are structural inserts made from folded, die-cut, or laminated paperboard.They are lightweight, fully recyclable, and widely used in both luxury and mass-market packaging.
Benefits of Cardboard Paper Inserts
- 100% recyclable in standard paper recycling streams
- Cost-effective compared with EVA or foam inserts
- Lightweight, helping reduce shipping weight
- Highly brand-friendly: can be printed, laminated, or color-matched
- Ideal for multi-compartment layouts and set packaging
- Works well together with molded pulp or outer trays
Limitations of Cardboard Inserts
- Not ideal for very fragile or heavy items
- Lower shock absorption than EVA, EPE foam, or molded pulp
- Can lose rigidity if exposed to moisture or humidity
Common Packaging Applications
- Cosmetic and skincare kits
- Chocolate boxes and confectionery gift packaging
- Apparel accessories such as scarves, ties, or socks
- Stationery and lightweight electronics
- Wine gift sets with multiple accessories or glasses
