Abstract

The invention relates to a polymer film (P) comprising at least one copolyamide, the copolyamide being produced by polymerising at least one lactam (A) and a monomer mixture (M) consisting of at least one C32-C40 dimer acid (B1), at least one C4-C12 diamine (B2) and optionally at least one C4-C20 diacid (B3). The invention also relates to a method for producing the polymer film (P) and to the use of the polymer film (P) as a packaging film.
