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 a whitening pigment and/or void-forming incompatible polymer at a concentration of from 2 to 35% by weight (based on the weight of the base layer (B)), and from 0.01 to 15% by weight (likewise based on the weight of the base layer (B)) of a pigment that absorbs laser energy. The invention further relates to a process for production of these films and to their use as laser-cuttable and laser-inscribable film.
