METHOD FOR PRODUCING A POLYMER FILM

The present invention relates to a process for producing a polymer film (P) comprising at least one copolyamide by extrusion of the copolyamide through a ring die and subsequent stretching of the tube thus obtained by blowing in air. The present invention further relates to the polymer film (P) obta...
