Abstract

A thermoplastic film for airbag covers contains a cover layer and a foam layer. The cover layer is made of at least two layers, having an outer layer and an inner layer, and an elongation at tear of the inner layer of the cover layer and of the foamed layer is considerably less than the elongation at tear of the outer layer of the cover layer.
