Abstract

The tubular packaging casing, in particular a synthetic sausage casing, comprised of fiber-reinforced cellulose, in which the fiber-reinforcement is coated at least on the outside with a cellulose layer, and a surface layer on the cellulose layer. The surface layer comprises a water-insoluble cationic resin containing particles of fibers of synthetic resin or cellulose, in particular particles of a vinyl chloride homopolymer or copolymer.
