Abstract
In a method for producing a thermoplastic film having a three-dimensionally textured, embossed surface, the film is subjected prior to a subsequent shaping kind of processing step to electron-beam crosslinking, which differently crosslinks the individual surface-area regions of the film, so that the regions that undergo greater degrees of drawing out during deforming have different degrees of crosslinking than their neighboring regions.
