ABSTRACT:
Biaxially oriented polyester films which have a polyester-containing base layer (B) and at least one overlayer (A) which comprises poly(m-xyleneadipamide) (MXD6) feature improved optical properties such as increased gloss and very good barrier properties, in particular toward passage of oxygen, and are therefore suitable as packaging materials for foods and other consumable items.
