Abstract:
A non-oriented, multilayered film comprising:a) a polyamide layer comprised of a heat stabilizer; and polyamide blend comprising:i) from about 30% to about 80% by weight of the blend of a nylon 6 polymer having a number average molecular weight of at least about 40,000;ii) from about 10% to about 30% by weight of the blend of a nylon 6,66 copolymer having a number average molecular weight of at least about 15,000;iii) from about 5% to about 40% by weight of the blend of a nylon 6,12 copolymer having a number average molecular weight of at least about 10,000;b) a polymethylpentene layer comprised of a heat stabilizer; and at least one polymethylpentene homopolymer, polymethylpentene containing copolymer or a blend thereof; andc) an adhesive interlayer attached between a surface of said polyamide layer and a surface of said polymethylpentene layer.
