ABSTRACT:
A biaxially oriented thermo-fixed multilayer film is described, consisting of thermoplastic polyester materials having different melting points and having an essentially scratch-free surface. The characterizing features of the multilayer film described consist in the fact that a cover layer of a polyester B is applied to at least one surface of a base layer of thermoplastic polyester A, said polyester B having a lower melting point than polyester A, and by the fact that no scratches longer than 3.0 mm and greater than 10 microns in cross-section are present on the surface of the cover layer.
