Disclosed is a polymer film, preferably a polyamide polymer film, which comprises at least one first layer and a second layer and is laminated onto a fabric. The material of the first layer has a glass transition temperature of less than -10 ~C while the material of the second layer has a glass transition temperature of less than 20 ~C. Preferably, the polymeric materials contain portions of polyamide blocks. The inventive fabric-polymer film laminate is suitable as a laminated material especially for an airbag.

La présente invention concerne un film polymère, de préférence un film polymère en polyamide, qui présente au moins une première couche et une seconde couche et qui est appliqué sur un tissu. La matière de la première couche présente une température de transition vitreuse inférieure à 10 ·C et la matière de la seconde couche présente une température de transition vitreuse inférieure à 20 ·C. Les matières polymères selon cette invention présentent de préférence des blocs polyamide. Le stratifié tissu-film polymère est adapté à un usage comme matière stratifiée composite, notamment pour un airbag.
