Abstract
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.
