Abstract
The present invention proposes a smokable planar or hose-type food casing or food casing film for food packagings, such as, e.g., sausage casings, shrink bags or the like on polymer basis, which is for the first time manufactured in the jet-blasting process from a homogeneous molten plastic material consisting of a plastic mixture consisting of at least of PA (polyamide) with PVAL (polyvinyl alcohol) and PEBAX (polyether block amide). The food casing or food casing film has a water vapor permeability that is at least 1 kg/m2 within 24 h. Its oxygen permeability at a film thickness of 30 μm is less than 2.1 cm3/m2 within 24 h. Moreover the present invention for the first time proposes a method for manufacturing it.
