Abstract:
1. A film comprising molding material consisting essentially of (i) resin consisting of polyester, said polyester comprising at least 80 mol % of a diacid radical component and from 80 to 100 mol % of a diol radical component, selected from diols having from 2 to 10 carbon atoms and from 0 to 20 mol % of a modified diol, (ii) optional waxes and (iii) polymeric modifiers based on ABS components and (iv) optionally a matting agent, wherein the molding material comprises from 30 to 97% by weight of polyester, waxes up to 3.0% by weight, and from 1.5 to 70% by weight of polymeric modifiers, where the percentages by weight are based on the total weight of the molding material; the ABS components are acrylonitrile-butadiene-styrene, alpha-methylstyrene-acrylonitrile, and/or styrene-acrylonitrile or a modified form of these; and the polymeric modifiers modifies the roughness (R and the polymeric modifiers comprise a mixture of alpha-methylstyrene-acrylonitrile and acrylonitrile-butadiene-styrene, resulting in films exhibiting an emboss stability temperature ranging from 115 to 170° C. and a transverse tensile impact strength ranging from 350 to 630 kJ/m and unoriented film has a thickness of from 100 μm to 1 mm, with the unoriented film being stretched by a factor of from 1.1 to 7 to a thickness from 15 to 800 microns after orientation.
