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 is produced by shaping the plastic or plastic mixture and subjecting to biaxial stretching according to processes that are known per se.
