The present invention relates to a polymer film (P) contacting at least one copolyamide. The copolyamide is prepared by polymerizing a first monomer mixture (M1), containing at least one C4-C12 dicarboxylic acid and at least one C4-C12 diamine, and a second monomer mixture (M2) containing at least o...
