Abstract
A thermoplastic film for the interior paneling of motor vehicles has a top layer with a structured surface layer and a foamed layer on the underside and with indentations or material weak points introduced on the reverse side. The top layer has a residual thickness of at least 35% in the region of the indentations and the foamed layer has a thickness between 15 and 50% of the density of the compact top layer.
Claims13
A thermoplastic film, comprising:
- an outer compact top layer formed with a three-dimensionally structured upper surface, said outer compact top layer having a given thickness and having a given density;
- a foamed layer on an underside of said top layer, wherein said foamed layer and said outer compact top layer are configured to be applied in a shaping processing step to a carrier corresponding to a component shape and to assume the component shape;
- the film being formed on a reverse underside facing toward the carrier with indentations or material weak points introduced from the reverse side;
- said top layer, in a region of said indentations or material weak points having a residual thickness of at least 35% of the given thickness of said top layer in an unindented, unweakened portion thereof;
- and
- said foamed layer having a density, measured at half a layer thickness of said foamed layer, between 15% and 50% of the given density of said top layer.
