    摘要: 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 μm 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.

    摘要: 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).
