Abstract

Process for producing transparent composite films from polyethylene and polyamide by coextrusion. A copolyamide consisting of 80 to 90 parts of epsilon -caprolactam and 10 to 20 parts of hexamethylenediamine adipate with a K-value of greater than 73 is used. The composite films are suitable in particular for packaging foodstuffs.
