ABSTRACT:
The invention relates to a white, coextruded, oriented polyester film with a base layer (B) and with at least one outer layer (A), where the base layer (B) includes from 2 to 35% by weight, based on the weight of the base layer (B), of a whitening pigment and/or void-forming incompatible polymer, and from 0.01 to 15% by weight, based on the weight of the base layer (B), of pigment that absorbs laser energy. The outer layer (A) includes from 1.0 to 35% by weight (based on the weight of the outer layer (A) of whitening pigment and/or void-forming incompatible polymer, and this pigment and/or polymer is identical with or different from the pigment and/or polymer in the base layer (B). The invention further relates to processes for production of these films and to their use as laser-cuttable film.
