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.
