Patent number: 11825865Abstract: A description is given of a tubular food casing having a fiber layer on the inside and having two or more polymer layers. The polymer layers include a first continuous polymer layer (A), with which the inner fiber layer or nonwoven-web layer is coated on the side of the tubular casing facing away from the inside, and completely covers the layer, and at least one polymer layer (B), and a monoaxially or biaxially oriented film based on polyamide and/or copolyamide. At least two of the polymer layers are joined to one another directly by a layer of adhesive. The inner fiber layer may absorb colour, smoke, aroma and/or flavour substance(s), such as liquid smoke or caramel, store these substances and transfer them to a food located within the casino. The casing is suitable as artificial sausage casing, especially for cooked-filling and scalded-emulsion sausage.Type: GrantFiled: November 20, 2017Date of Patent: November 28, 2023Assignee: Kalle GmbHInventors: Erna Kastl, Jens Fögler, Ulrich Delius, Martina König

Publication number: 20220240522Abstract: The present invention relates to a tubular, seamless, biaxially stretched, smoke-permeable and water vapour-permeable, colouristically neutral and transparent, single-layer food casing formed from a mixture including 50 to 95% by weight of aliphatic (co)polyamide, 3 to 40% by weight of at least one vinyl (co)polymer having units of N-vinyl-2-pyrrolidone and 1.5 to 7.0% by weight of at least one aliphatic diol and/or aliphatic polyol, based in each case on the weight of the mixture. The diol and/or polyol is homogeneously distributed in a matrix formed by the aliphatic (co)polyamide. The food casing is produced by an extrusion method with biaxial tube stretching and subsequent heat-setting. It is particularly suitable as synthetic sausage casing, especially for raw sausage, such as salami or mettwurst.Type: ApplicationFiled: February 2, 2022Publication date: August 4, 2022Applicant: Kalle GmbHInventors: Ulrich DELIUS, Igor RASKITA

Patent number: 10959440Abstract: A tubular, seamless, water vapour permeable, smokable, biaxially draw-oriented and partially or completely heat-set food casing is provided having at least two layers based on thermoplastic polymers. At least one layer A, which does not form the inside layer, comprises a blend of aliphatic (co)polyamide and at least one hydrophilic polymer, while the inside layer I comprises a blend of aliphatic or isocyclic (co)polyamide and a block copolymer selected from polyether-amide, polyether-ester and polyether-urethane. The casing is produced by a tubular-film blowing process or a process with biaxial tubular-film draw-orientation. The casing is envisaged more particularly as synthetic sausage casing, especially for smoked raw sausage, such as salami.Type: GrantFiled: January 24, 2019Date of Patent: March 30, 2021Assignee: Kalle GmbHInventors: Ulrich Delius, Igor Raskita

Patent number: 9585406Abstract: The invention relates to uncooked dry or semi-dry sausage products in tubular casings that are based on an optionally-coated textile material. The tubular casing has a longitudinal seam with a sealing strip. On the sealing strip is located a discontinuous layer of a sealing polymer. The sealing strip is bonded to the casing essentially at sealing points defined by the discontinuous layer. The invention further relates to a process for producing the uncooked dry or semi-dry sausage product.Type: GrantFiled: January 21, 2009Date of Patent: March 7, 2017Assignee: Kalle GmbHInventor: Ulrich Delius

Patent number: 9532577Abstract: A flexible tubular food casing having a flat support material is provided which, on at least one side, has a continuous coating based on a hotmelt polymer, with the coating preferably situated on the outside. The continuous coating has a weight per unit area of 3 to 200 g/m2, preferably 15 to 50 g/m2. The hotmelt polymers have an MVR value in the range of about 25 to 500 cm3 per 10 min, measured at 190° C. with a load of 2.16 kg. The flexible tubular food casing is suitable as a synthetic sausage casing for raw sausage, scalded-emulsion sausage or cooked-meat sausage.Type: GrantFiled: February 22, 2011Date of Patent: January 3, 2017Assignee: Kalle GmbHInventors: Jens Foegler, Michael Seelgen, Ulrich Delius

Patent number: 7803437Abstract: Disclosed is a shined tubular food casing based on a thermoplastic blend of at least one polyamide and/or copolyamide and at least one hydrophilic component. The casing is biaxially stretch-oriented and impregnated on the inside and/or outside with a component which allows the pleats which are formed during shining of the casing to adhere to each other. The component preferably comprises at least one polymer. The casing is preferably shirred at a ratio of 80:1 to 500:1. The inventive shined casing is particularly stable from a mechanical perspective and can therefore be used especially for the production of cooked sausages, scalded-emulsion sausages, and small sausages on fully automatic sausage stuffing and clipping apparatuses.Type: GrantFiled: August 23, 2004Date of Patent: September 28, 2010Assignee: Kalle GmbHInventors: Ulrich Delius, Dirk Auf Der Heide, Gerhard Grolig
