METHOD FOR TEXTURING A FILM

摘要

The present invention provides a method for treating a surface of a layered polymeric structure. The method includes the steps of: (1) providing a first sheet of material (60), (2) providing a second sheet of material (62), (3) positioning the first sheet (60) or the second sheet (62) to overlap at least a portion of the other sheet to define an interference zone (64), (4) directing a first polymeric material (65) into the interference zone (64) to adhere the first sheet (60) to the second sheet (62) to form the layered structure (66); and (5) texturing a surface of the first sheet (60) or the second sheet (62) to form a pattern on the surface.
