ABSTRACT:
The invention relates to a transparent, biaxially oriented polyester film with a base layer B which is composed of at least 80% by weight of a thermoplastic polyester, and with at least one outer layer A. Another polymeric layer made from a copolymer crosslinked using an acrylic and/or methacrylic compound, has been applied to that side of the film opposite to the outer layer A. The film has low oxygen transmission and exhibits very good adhesion between the respective layers. The coated film moveover has low coefficient of friction, excellent windability, and excellent antistatic performance. It is particularly suitable for packaging purposes, specifically for packaging foodstuffs or other consumable items. The invention further relates to a process for the production of the film.
