EVA Separator
Die-cut EVA is a protective foam solution precisely produced with custom dies to match the size and form of your product. It provides high protection for the safe transport and storage of electronic devices, tool cases, medical equipment, automotive parts and industrial products. Produced with project-specific size, shape and density options.
Key Properties
- Precision die-cutting
- Perfectly product-fitted design
- High impact protection
- Scratch & vibration protection
- Various thickness & density options
- Suitable for series production
- Made-to-order production
Overview
An EVA separator is a die-cut dividing layer that stops products touching each other, or the wall of the box, during handling and transport. The closed-cell structure of ethylene-vinyl acetate foam spreads impact across the surface and damps it, so parts seated in individual cavities stay put for the whole journey.
Why a die-cut separator
Loose fill dropped into a stock box takes no account of a product's centre of gravity or its vulnerable points. In a separator cut to the product's dimensions every part has its own cavity: the load cannot shift in transit, parts cannot rub against each other, and the void space inside the box disappears. In multi-layer arrangements separators stack, letting the same carton carry more parts.
Choosing density and thickness
The right density follows the weight of the part being protected. Light electronic components are damped well by low-density EVA, while heavy metal parts need high-density — otherwise the foam bottoms out and the protection is lost. Thickness follows drop height: the material left beneath the cavity is the distance over which the impact is absorbed.
How they're produced
Separators are cut with steel-rule dies, CNC or waterjet. CNC is more economical for low volumes and complex geometry; a steel-rule die wins on high-volume repeat work. Production follows sample approval, with dimensional tolerance and cavity depth verified on that first sample.
As a packaging separator, EVA is chosen where the layer touching the part must be both soft and clean: the closed cells do not shed and the cut edge stays crisp.

Frequently Asked Questions
- What's the difference between an EVA and a polyurethane foam separator?
- EVA is closed-cell: it doesn't absorb water, absorbs more impact and cuts with a clean edge. Polyurethane foam is open-cell — softer and cheaper, but it retains moisture. EVA suits heavy or sensitive parts; polyurethane suits light parts in dry conditions.
- Do you produce samples?
- Yes. Send the product dimensions or a technical drawing and we produce a sample first; production follows once cavity depth and fit are approved.
- What's the minimum order quantity?
- It depends on the cutting method. CNC handles low volumes; with a steel-rule die the tooling cost means unit price falls as quantity rises. Send dimensions and quantity and we'll pick the right method with you.
- Do you make antistatic EVA separators?
- Antistatic foams are available for static-sensitive electronic components. Just state your ESD requirement with the enquiry.
