摘要

Multilayer-film, particularly for packaging purpose, comprises at least a first layer containing thermoplastic polyester and at least a second layer containing thermoplastic starch. Independent claims are included for: (1) a method for producing a multilayer-film comprising extruding a material containing thermoplastic polyester to form a first layer, extruding a material containing thermoplastically processable starch to form a second layer, and at least partially surface bonding of the individual layers to form the multilayer-film; and (2) a packaging for food items such as fresh meat, bakery product, cheese, fresh fruit or vegetables, drinks and/or coffee, comprising the multilayer-film.
