Laminated multilayer polymer containing film comprising a copolyamide of a diamine, a dimer acid and a lactam

A laminated multilayer polymer containing film (P) consisting of:

• (I) at least one layer consisting of at least one copolyamide,
• wherein the at least one copolyamide is prepared by polymerizing the following components:
• (A) 15% to 84% by weight of at least one lactam, and
• (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 weight of components (A) and (B), and
• (II) at least one further layer, wherein the at least one further layer is at least one 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;
• and
• (III) optionally one or more additives selected from the group consisting of stabilizers, dyes, antistats, tackifiers, anti-blockers, processing auxiliaries, antioxidants, light stabilizers, UV absorbers, lubricants, nucleating aids, and combinations thereof.
