Abstract:
1. An intrinsically stable shirred tubular single-layer food casing consisting essentially of a mixture of synthetic polymers, said mixture of polymers comprising (i) amide polymer consisting of aliphatic copolyamide including nylon 6/66 and/or nylon 6/12, and (ii) at least one further polymer selected from the group consisting of polyurethanes, polyether block amides, copolyesters, biodegradable polyesters, and water-soluble polymers, said food casing having, without separate support, sufficient intrinsic stability to be processed on fully automatic stuffing machines, wherein said shirred food casing bends under the effect of its own weight by no more than 20%, based on the length between two support points and at room temperature, said food casing further exhibits a water vapor permeability of 5 to 1000 g/m and the food casing water vapor permeability is essentially imparted by the synthetic polymers.
