ABSTRACT:
The invention concerns a polyester film with improved abrasion resistance, dimensional stability, drawability and slip properties. The film is characterized by the fact that it contains 0.005 to 5.0% by weight of organic, preferably hardened or crosslinked, particles with narrow particle size distribution in a range between 0.01 and 5 microns, as well as a nucleating agent in an amount from 0.01 to 10% by weight, both values related to the weight of the polymers which form the film.
