Ethylene Vinyl Acetate Copolymer Eva

These material are used when a combination of softness toughness flexibility and polarity are needed.

Ethylene vinyl acetate copolymer eva.

The food and drug administration fda has stated that ethylene vinyl acetate is safe when used in food production packaging or transportation and it s not an especially dangerous material. It is an extremely elastic and tough thermoplastic of excellent clarity and gloss and with little odor. Eva offers good bondability and adhesion to polar substrates in extrusion coating and multi layer film applications. Both effects result in a lowering of the tg of the final copolymer.
