DuPont ™ Elvax ® EVA (ethylenevinyl acetate) copolymer resins offer many performance properties, from low seal initiation temperatures to excellent flex - crack resistance, for packaging applications.
It is proposed as a replacement for oxygen - barrier films that rely on the use of ethylenevinyl alcohol copolymer (EVOH) or nylon MXD6, which lose their barrier properties when exposed to water.
