MULTILAYER TUBULAR FOOD CASING WITH VARIABLE OUTER LAYER THICKNESS THE OUTER LAYER HAVING RELIEF FIBROUS-NETLIKE STRUCTURE

摘要

Disclosed is a synthetic tubular casing for food products with an inhomogeneous in respect to thickness outer layer having a relief fibrous-netlike structure, and having a reduced tendency to disrupt when its surface is disturbed. The relief fibrous-netlike structure is formed by alternating of thinner and thicker regions, wherein the maximum thickness of the layer in the thicker region is 80 µm, in the thinner region this layer may be thinned up to zero. The outer layer is made from a polymer or a mixture of polymers, each of which has a melt flow index from 0.2 to 15 g/10 min, measured according to ASTM D 1238 A. The synthetic casing may comprise two or more layers, and is used as a casing for various types of sausage products and processed cheeses.
