Tubular film for packing and casing paste-type foodstuffs especially sausage and cheese

Abstract

The invention relates to a tubular film for packing foodstuffs that in the state in which they are introduced into the tube are paste-like or fluid and that either after packing are heated to approximately 70.degree. to 95.degree. C. or are packed in the hot, fluid state. The tubular film consists of at least one aliphatic polyamide, of which the glass transition temperature of .gtoreq.321 K in the dry state can be lowered, by moisture absorption, to 293 K, or of a mixture of this polyamide with at least one ionomer resin, wherein the ionomer resin may be partly or completely replaced by a modified ethylene/vinyl acetate copolymer. The tubular film according to the invention lies wrinkle-free against the contents after cooling. The tubular film is produced by shaping the plastic or plastic mixture and subjecting to biaxial stretching according to processes that are known per se.
