TRANSPARENT, BIAXIALLY ORIENTED POLYESTER FILM WITH A SMOOTH SURFACE ON ONE SIDE AND GOOD COILABILITY

The invention relates to an at least three-layer biaxially oriented polyester film including at least one base layer B, one rough outer layer A and one smooth outer layer C, where the layers A and C are external layers arranged on opposing surfaces of the base layer B. The outer layer A includes cal...

Beschreibung
Zusammenfassung:	The invention relates to an at least three-layer biaxially oriented polyester film including at least one base layer B, one rough outer layer A and one smooth outer layer C, where the layers A and C are external layers arranged on opposing surfaces of the base layer B. The outer layer A includes calcium carbonate particles. The outer layer C includes less than 0.1% by weight of particles (where the percentage by weight data are based on the weight of the layer). The polyester used to produce all of the layers includes no 2,6-naphthalenedicarboxylic-acid-derived units as repeating units. The entire film includes less than 0.3% by weight (based on the weight of the entire film) of particles. The invention further relates to processes for producing the film, and also to use of the latter as process film for the provision of surface properties, in particular for furniture surfaces.
