| 摘要 |
A multi-layer film useful in vacuum skin packaging and other packaging applications, and having a combination of good implosion resistance, formability and high oxygen barrier characteristics, includes a core layer having an oxygen barrier material such as ethylene vinyl alcohol copolymer (EVOH) and a layer or layers comprising an amorphous nylon with or without a low flexural modulus polymeric material such as low modulus nylon (polyamide or copolyamide). Layers of ethylene vinyl acetate copolymer (EVA) or other olefin homopolymers or copolymers, polymeric adhesive layers, a heat-sealable layer, and a heat resistant layer are also disclosed. A composition of matter comprising a blend of an amorphous nylon and a low modulus polymeric material, especially a low modulus nylon, is also disclosed. |
