Abstract: The invention relates to a biaxially drawn multilayer tubular film consisting of at least five layers, in which the external and two other layers contain aliphatic (co)-polyamide in a quantity equal to or greater than 50% by weight and are differently assembled. The inventive tubular film is produced by coextrusion and, thereby is seamless. Said tubular film can be used in the form of food product packagings, in particular as synthetic sausage casing.

Abstract: The invention relates to a single- or multi-layered food casing, made from a thermoplastic mixture which comprises at least one aliphatic polyamide and/or copolyamide, at least one or more synthetic water-soluble polymers and at least one organic and/or inorganic filler. The skin has a water vapor permeability, as determined according to DIN 53122, in the non-oriented, monoaxially or biaxially oriented state of 50 to 1500 g/m2·d. The food casing is particularly suitable for use as an artificial sausage casing, particularly for raw sausages.

Abstract: A tube-shaped food wrapper is disclosed, particularly a sausage wrapper, comprising at least two layers. The inner layer facing the food is provided with a matrix made of an organic, thermoplastic polymer material and a powdered organic filler which is embedded therein and contains a food additive that can be transferred to the filling material. The organic filler preferably consists of a carrageenan powder while the food additive preferably consists of a liquid smoke. At least one additional layer has barrier properties, i.e. is provided with a reduced permeability to water vapor and/or atmospheric oxygen. Layers based on polyolefin or polyamide are particularly suitable for the addtional layer(s).

Abstract: A section of a tubular foodstuff casing closed at one end with an end with a flat transverse seam, wherein the casing comprises a heat-sealable polymer material, or has a layer or a coating thereof on an inner side thereof, or wherein the casing comprises (i) uncoated or coated textile material, (ii) knitted material and/or, (iii) nonwoven, or non-fiber-reinforced or fiber-reinforced cellulose, where said flat transverse seam comprises a jointing seam comprising a sealed seam and/or a adhesive seam.

Abstract: The invention relates to a food casing made of a thermoplastic blend, which comprises at least one aliphatic polyamide and/or copolyamide and/or at least one aliphatic and/or partially aromatic copolyamide containing glycol and/or polyglycol units, in addition to at least one inorganic and/or organic filler. The casing has a maximum surface roughness Rmax of between 7 to 60 ?m and a water vapor permeability of at least 50 g/m2·d. Said casing thus has a particularly matt, rough, extremely natural surface structure. The casing is produced by extrusion with the aid of an annular-shaped die and subsequent blow moulding or biaxial stretch orientation. It is suitable for use as an artificial sausage casing, in particular for raw sausage, such as salami.

Abstract: A seamless, tubular food casing produced by extrusion or coextrusion, wherein at least one layer of the casing comprises a mixture of: a) thermoplastic starch and/or a thermoplastic starch derivative and b) at least one further polymer, in which the further polymer is a homopolymer or copolymer comprising at least one selected from the group consisting of hydroxycarboxylic acid units, a poly(ester urethane), a poly(ether urethane), a poly(ester ether urethane) and a poly(alkylene carbonate) of the formula —[CHR1—CHR2—O—CO—O—]n, where R1 and R2 independently of one another are a hydrogen atom or a (C1-C4)alkyl group and n is an integer from 10 to 5000, and wherein the casing carries internally at least one transferable coloring, aroma substance and/or flavoring.
