摘要

The invention relates to a single-layer or multilayer tubular food packaging film that can be smoked, air-dried, and peeled, especially peeled in a fully automatic manner, particularly a sausage casing for smoked and/or air-dried sausages or meat. Said polymer-based food film is produced from a homogeneous plastic melt in a (co-)extrusion film blow molding plant using extruded plastics that are fed to a nozzle of a blow head and is biaxially stretched in a triple bubble process, the homogeneous plastic melt being produced from a plastic mixture of PS or a mixture of various PS and PVOH and/or PEBA. The invention further relates to a method for producing the food film.
