Abstract
Biaxially oriented polyester films which have a polyester-containing base layer (B) which additionally comprises poly(m-xyleneadipamide) and which is coated on at least one side with a barrier layer (D), the barrier layer comprising polyvinyl alcohol and a copolymer of maleic acid and acrylic acid, feature improved optical properties such as high gloss and low opacity, and very good barrier properties, in particular with respect to oxygen passage, and are also suitable as packaging materials for foods or other consumable items as a consequence of their insensitivity toward moisture.
