Patent ID: 11629226

Abstract:
A laminated multilayer polymer containing film (P) comprises at least one layer comprising at least one copolyamide wherein the copolyamide is prepared by polymerizing the following components: (A) 15% to 84% by weight of at least one lactam, (B) 16% to 85% by weight of a monomer mixture (M) comprising the following components: (B1) at least one C32-C40 dimer acid and (B2) at least one C4-C12 diamine, where the percentages by weight of components (A) and (B) are each based on the sum total of the percentages by weight of components (A) and (B) and wherein the laminated multilayer polymer containing film (P) comprises at least one further layer, where the at least one further layer is selected from the group consisting of (i) at least one further polymer (FP) selected from the group consisting of polyolefins, poly(ethylene-vinyl alcohols), poly(ethylene-vinyl acetates), polyethylene terephthalates, polyvinylidene chlorides, maleic anhydride-grafted polyolefins, polyesters and ionomers and (ii) aluminum metal and/or tin metal.
