Abstract: The invention relates to a process for the treatment, in particular for the roughening, of the surface of hydrated cellulose shaped articles, in which at least one cellulase is allowed to act on the surface and is then inactivated permanently. The tubular films modified in this way are particularly suitable as foodstuff casings, specifically as sausage casings.

Abstract: The invention concerns flat or tubular cellulose-based foodstuff casings which are prepared by extruding (“spinning”) cellulose dissolved in N-methyl-morpholine-N-oxide by means of a nozzle with an annular gap. After extrusion, the casings are stretched transversely in ambient air by blow moulding, and are then treated with an NMMO-containing aqueous spinning bath. The tubular casings are particularly suitable as sausage casings. Cut open, they can also be used as flat foils.

Abstract: A tubular food casing based on regenerated cellulose, which casing may be fiber-reinforced, is coated on its inner surface with a copolymer which includes 50 to 84% by weight of vinylidene chloride units, 2 to 20% by weight of acrylonitrile units, 1 to 10% by weight of acrylic acid units, and 1 to 47% by weight of (C1-C18)alkyl (meth)acrylate units. The casing has high water vapor barrier and oxygen barrier characteristics. The shirring folds and lay-flat edges which result during the production and processing of the casing remain undamaged over long storage periods. The inner coating, in addition, shows no hot-water haze on simmering. The casing is particularly suitable as an artificial sausage casing.

Abstract: The invention relates to a seamless, tubular sausage casing based on cellulose hydrate having a continuous coating made of a polymeric material on its outer surface, which is permeable to hot smoke and cold smoke. The coating preferably has a thickness of from 3 to 10 &mgr;m and can also comprise or consist of a plurality of individual layers. The coating can be applied by conventional coating processes, and in addition also by single or repeated whole-surface printing. The casing is adapted especially for smoked liver sausage.

Abstract: The invention relates to a tubular food casing, one surface of which has a continuous layer which is solid under standard conditions of temperature and pressure, prepared from a mixture made from a wax solid under these conditions and/or from a wax-like component, from a liquid smoke, and from an emulsifier with the aid of which a stable water-in-oil emulsion can be formed. The layer adheres firmly to the casing and is also flexible, so that the outer side of the casing can be turned inside out without difficulty. When the sausages produced therewith are cooked or scalded, the wax or the wax-like component melts so that the liquid smoke can migrate onto the surface of the meat emulsion and there produce the desired characteristics of smoking.

Abstract: A tubular casing that is capable of receiving a product therein in an outstretched state, said casing comprising:

Abstract: The present invention relates to a regenerated cellulose based sponge material with an inner viscose fiber reinforcement having a staple fiber length of 5-50 mm and impregnated with a biocide agent. Also disclosed is a regenerated cellulose based sponge material with an inner cotton fiber reinforcement having a staple fiber length of 5-50 mm and impregnated with a biocide agent. The coagulation and regeneration takes place in a bath that has a pH of 13 or higher and which includes Glauber's salt, NaOH and water.

Abstract: An at least four-layer tubular biaxially oriented food casing having an outer layer which includes a mixture of at least one aliphatic and at least one partly aromatic (co)polyamide with or without pigments, and an inner layer which includes aliphatic (co)polyamide, wherein, between these layers, a layer of an ethylene/vinyl alcohol copolymer or a blend of the ethylene/vinyl alcohol copolymer with an aliphatic or partly aromatic (co)polyamide and/or with an olefinic (co)polymer and/or an ionomer resin and a layer of an olefinic (co)polymer with or without adhesion promoters, pigments, and/or UV absorbers are arranged. The casing has a high water-vapor and oxygen barrier. It is particularly suitable as synthetic sausage casing, and can also be used for packaging cheese or animal feed.

Abstract: The invention relates to a bonded nonwoven fiber fabric and packaging films strengthened with such a fabric, especially sausage casings based on celluloses. The nonwoven fiber fabric itself can be used as teabag paper. Bonding is achieved through treatment of a solution comprising cellulose, N-methylmorpholime-N-oxide and water. Bonding can be strengthened by a polyamine polyamide epichlorohydrin resin added to the fibrous pulp.

Abstract: An apparatus 17 for continuously forming rings of thermoplastic, shrinkable tubular casings 1 includes an unwinding roller 20, a first pair of pinch rolls 2, a ring-forming tool 3, a second pair of pinch rolls 15 and a winding-up roller 21. The tubular casing 1 is passed from the unwinding roller 20 through the pair of pinch rolls 2 and runs along a running-zone A into the ring-forming tool 3, which includes a spiral 19 and guide rollers 7 and 8 on an outer side 5 and an inner side 6, respectively, of the tubular casing 1 as well as a heater 4 for generating hot air. After covering a running-out zone B, the ring casing 16 leaving the ring-forming tool 3 runs through the second pair of pinch rolls 15, which pinches off the gas blown in at low gauge pressure in the section of the tubular casing 1, or of the ring casing 16, between the first pair of rolls 2 and second pair of rolls 15, with the result that said gas remains only in the section mentioned.
