Patent number: 6919112Abstract: The invention concerns a biaxially stretched and thermoset tubular seamless single- or multi-layered foodstuff skin wherein the layer, or, a multi-layered skin wherein at least one of the layers, contains a block copolymer with “hard” aliphatic polyamide blocks and “soft” aliphatic polyether blocks, the block copolymer corresponding to one of formulae (I) to (III), Ea—(NH—[CH2]x—CO)m—Xa—(A—O)n—A Xa—(CO—[CH2]x—NH)m—Ea (I), (II), —[X—(CO—[CH2]x—NH)o—Y—X—(A—O)p—A]-(III). The invention is particularly suitable as a skin for a sausage which is to be boiled or heated in water, and does not form folds when the filling is introduced manually, with no or only slight pressure.Type: GrantFiled: October 24, 1997Date of Patent: July 19, 2005Assignee: Kalle Nalo GmbH & Co.

Patent number: 6761944Abstract: 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.Type: GrantFiled: January 13, 1999Date of Patent: July 13, 2004Assignee: Kalle Nalo GmbH & Co. KGInventors: Klaus-Dieter Hammer, Martina Koenig, Theo Krams

Patent number: 6656547Abstract: 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.Type: GrantFiled: September 1, 1998Date of Patent: December 2, 2003Assignee: Kalle Nalo GmbH & Co. KGInventors: Klaus-Dieter Hammer, Herbert Gord, Gerhard Grolig, Reinhard Maron, Klaus Berghof

Patent number: 6627282Abstract: 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.Type: GrantFiled: September 25, 1998Date of Patent: September 30, 2003Assignee: Kalle Nalo GmbH & Co. KGInventors: Klaus-Dieter Hammer, Leo Mans, Gerhard Grolig

Patent number: 6485802Abstract: 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.Type: GrantFiled: March 17, 2000Date of Patent: November 26, 2002Assignee: Kalle Nalo GmbH & Co.KGInventors: Klaus-Dieter Hammer, Gerhard Grolig, Bernd-Adolf Lang, Hans-Werner Seelgen

Publication number: 20020004088Abstract: 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.Type: ApplicationFiled: February 8, 2001Publication date: January 10, 2002Applicant: Kalle Nalo GmbH & Co.

Patent number: 6235302Abstract: 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.Type: GrantFiled: March 31, 1999Date of Patent: May 22, 2001Assignee: Kalle Nalo GmbH & Co.

Patent number: 6194040Abstract: 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.Type: GrantFiled: May 5, 1998Date of Patent: February 27, 2001Assignee: Kalle Nalo GmbH & Co. KGInventors: Ulrich Delius, Karl Stenger, Gerhard Grolig

Patent number: 6048917Abstract: 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.Type: GrantFiled: March 16, 1999Date of Patent: April 11, 2000Assignee: Kalle Nalo GmbH & Co.
