Claim Text:
1. A thermoplastic film, comprising: crosslinked polymeric materials having a three-dimensionally structured, embossed surface; the crosslinked polymeric materials including first regions and second regions, said first regions being subjected to higher degrees of drawing in a subsequent shape-imparting processing step than said second regions; said crosslinked polymeric materials being formed by subjecting a film to electron beam crosslinking for crosslinking said first regions differently from said second regions, such that said first regions have degrees of crosslinking higher than neighboring second regions and said first regions have a greater strength than neighboring second regions; said film having a gel content, said first regions having a gel content of at least 30%, and a difference in said gel content between said first regions of said film having a high degree of crosslinking and said second regions of said film having a low degree of crosslinking being from 10 to 60%; and said film formed from a thermoplastic elastomer.
