Die Cut High Density EVA Foam Box Tray For Wine Jewelry Packaging
EVA Foam is the abbreviation of ethylene-vinyl acetate. It is an
ethylene-vinyl acetate copolymer material composed of ethylene (E)
and vinyl acetate (VA). EVA foam board has the advantages of
waterproof, moisture-proof, shock-proof, sound insulation, heat
insulation, heat preservation, recyclable, environmentally
friendly, good impact resistance, etc. It also has good chemical
resistance.
It has a high level of chemical cross-linking. The result is a
semi-rigid product with a fine, uniform honeycomb structure
suitable for a variety of situations and applications.

FAQ:
Q1:How to classify EVA foam according to hardness?
1) High elastic EVA:15-25°
2) Ordinary EVA:38°
3) Medium density EVA:45-60°
4) High density EVA:65-80°
Q2:.What types of EVA Foam We Offer?
We provide a wide range of EVA foam products, including sheets,
mats, and strips.
Our foam comes in various densities and resistance levels to suit
different applications.
Q3:What's the relationship between hardness and density of EVA
foam?
EVA foam density is divided into three standards according to
hardness:
1) High foaming hardness is 5%-40%,
2) Secondary foaming hardness is 40%-55%
3) Primary foaming hardness is 55%-75%,
