Abstract:
1. A thermoplastic film without visible seam relaxation, 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, opposite from said top layer and facing toward the carrier with indentations or material weak points introduced from the reverse underside; said top layer, in a region of all 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 in said foamed layer half way between the reverse underside of said foamed layer and said underside of said top layer, between 15% and 50% of the given density of said top layer.
