The invention relates to a copolyamide (CoPA) produced by polymerizing a first monomer mixture (M1) and a second monomer mixture (M2), the second monomer mixture (M2) containing 1,5-diamino-3-oxapentane. The invention further relates to a polymer film containing the at least one copolyamide (CoPA), and to a process for producing the polymer film.
