摘要： Process for the preparation of translucent matt polyurethane films with a rough surface by extrusion of thermoplastic polyurethane elastomers to flat films or tubular films, characterized in that the extruded film is stored until it has a turbidity of > 15%, measured in accordance with ASTM D 1003, and the two film surfaces are then embossed with the aid of embossing rolls with a different number of grids, each in the range from 20 to 100 grids/cm.sup.2, under a pressure of 5 to 20 bar at temperatures of 130.degree. to 175.degree. C.
