SINGLE-LAYER OR MULTILAYER TUBULAR FOOD PACKAGING FILM THAT CAN BE SMOKED AND AIR-DRIED, AND METHOD FOR THE PRODUCTION THEREOF

摘要

The invention relates to a single-layer or multilayer tubular food packaging film that can be smoked and air-dried, especially a sausage casing for smoked and/or air-dried sausages or meat. Said polymer-based food film is produced from a 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 PET or a mixture of various PET and PVOH and/or PEBA. The invention further relates to a method for producing the food film.
