    Abstract: A web-shaped or tubular packaging film for use in food packaging applications, particularly as a sausage casing, is comprised of a carrier layer based on fiber-reinforced celulose and a closed thermoplastic, sealable resin coating based on copolymers containing vinylidene chloride (VDC) units. To improve the kink resistance, this resin coating is built up from at least two superposed layers, the first resin coating layer adjacent to the carrier layer being composed of a VDC copolymer forming flexible films and the outer, second resin coating layer being composed of a VDC copolymer forming rigid films. The web-shaped film is suitable for the production of tubular packaging casings, in particular sausage casings, with a longitudinal seam.

    Abstract: A tubular food casing comprising a film which has been bent to form a tubing, the longitudinal edges of which are joined to one another by means of an adhesive tape, which forms a glued seam. The adhesive tape comprises a plurality of incisions, ending in the area of the glued seam, which extend transversely to its longitudinal direction. In the area of the incision ends, the adhesive tape is firmly bonded to the film. The bond strength between the adhesive tape and the film is greater than the tear resistance of the film.

    Abstract: Disclosed is a smoke-permeable film suitable for the production of tubular casings, especially sausage casings, including a film of fiber-reinforced regenerated cellulose and a layer of thermoplastic sealable resin containing a vinylidene group-containing copolymer. The thermoplastic sealable resin has a smoke-permeable structure, including linear discontinuities running parallel to one another, and is anchored to the surface of the cellulose film with the aid of an adhesion promoting layer. The resin layer completely coats at least one of two surfaces of the cellulose film. Also disclosed is a casing made of the smoke-permeable film and a method for producing the film.

    Abstract: The invention relates to a preferably tubular food casing based on synthetic material, in particular polyamide, in which the layer, or at least one of the layers, includes at least one metal salt having antimicrobially active metal ions. The metal salt preferably includes ions of silver, copper or zinc. In the event of a multi-layered casing, the at least one outer layer comprises a said metal salt. In the production of the casing, preferably a master batch is used which comprises about 5 to 40% by weight of the metal salt. The food casing is preferably used as artificial sausage casing.

    Abstract: A device and method of producing a multi-layer film composite is provided. In accordance with the device and method, a temperature-controllable or heatable roll serves as a sealing tool, on the circumferential surface of which a number of plastic film webs are sealed together under the application of pressure and heat. The plastic film webs come into contact with the circumferential surface of the roll at equal or varying distances from each other and are guided over pressure rolls. These pressure rolls are in contact with the circumferential surface of the heatable roll under pressure. The plastic film webs pass through the gaps between the pressure rolls and the heatable roll. The plastic film webs are alternately sealing layer-free or provided on one or both sides with sealing layers, which are fused by the action of heat, so that sealing of the laminated plastic film webs on the circumferential surface of the heatable roll occurs.
