Abstract:
The present invention relates to a polymer film (P), comprising at least one copolyamide, wherein the copolyamide has been prepared by polymerizing at least one lactam (A) and a monomer mixture (M). The present invention further relates to a process for producing the polymer film (P) and to the use of the polymer film (P) as packaging film.
