Abstract

Die vorliegende Anmeldung betrifft eine Folie aus Polymer-Formmassen, wobei sie im wesentlichen aus Mischungen von Ester-Amid-Polymerisaten und thermoplastischen Polyurethanen besteht, wobei die Ester-Amid-Polymerisate ihrerseits im wesentlichen aus überwiegend linearen Ester-Amid-Copolymerisaten gebildet werden, deren Molekulargewichte über 10.000 g/mol betragen und die thermoplastischen Polyurethane einen Schmelzpunkt unter 200 °C aufweisen.
