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.
Claims20
A tubular packaging casing, consisting essentially of:
- a base tube of fiber-reinforced cellulose, said fiber reinforcement being completely coated with a cellulose layer at least on the outside;
- and
- an outer surface layer applied to the entire surface of the outer cellulose layer of said base tube, said outer surface layer comprising a water-insoluble cationic resin and particles or fibers of cellulose or a synthetic resin, wherein said particles or fibers are distributed throughout said outer surface layer thereby producing a roughened outer surface which constitutes a means to grip the casing as it is pushed onto a stuffing horn in the wet state.
