More Information
Summary:1. A tubular packing casing for pasty materials, in particular a sausage casing, based on a polyester film exhibiting high heat shrink resistance, characterized in that said casing is comprised of a multilayer polyester film (1, 2) which has been shaped into a tubing and whose edge zones extending in the direction of the longitudinal axis form a heat-sealed seam (5, 10, 11) obtained by overlapping said edge zones and/or by means of a film strip (4), and in that said multilayer polyester film (1, 2) is comprised of a carrier layer (B) based on a predominantly crystalline, linear polyester and of a heat-sealable layer (A) which is present on at least one surface of said carrier layer (B) and which has a thickness of 4 mu m or less and is based on a predominantly amorphous, linear polyester.
