ABSTRACT:
A multilayer heat-sealable chlorine-free odor barrier film having relatively low modulus, high interlaminar strength, and low noise upon flexing is provided. The film comprises an odor barrier layer of an amorphous polyamide resin blended with an anhydride-modified olefinic polymer or copolymer. The film also includes at least one heat-sealable skin layer, preferably two such skin layers on opposite sides of said odor barrier layer, composed of an ethylene polymer or copolymer. Pouches formed of such multilayer films are also disclosed.
