Abstract
A sausage casing of an isotropic spun fleece of at least one polyamide, containing no binding agent, is joined in the longitudinal direction so as to form a tube and is partially compressed. Further, the invention relates to a process for the production of the sausage casing and its use for containing sausage products that are air-cured. Special mechanical and elastic characteristics are achieved by partial compression whereas the gas and water permeability for the raw sausage is retained to the required extent. The casing shrinks with the filling on curing, remains wrinkle-free, does not allow grease to escape, and can be easily peeled.
Claims14
A raw sausage casing which comprises:
- a spun random fleece which forms the sausge casing, with said fleece comprising at least one polyamide which contains no binding agent, and with said fleece being provided with edges and a longitudinal axis, wherein said edges are joined in a longitudinal direction along said longitudinal axis in such a way as to form a tube including webs of uncompressed fleece and areas of compressed fleece to avoid disadvantages of fray encountered during unpeeling of the sausage casing, said fleece further being provided with predetermined areas which are embossed by partial compression, with said partial compression having an area compression ratio V.sub.F, which is a ratio of compressed fleece surface that represents area sum of all predetermined areas compressed by being embossed relative to uncompressed fleece surface representing area sum of all webs, and a depth compression ratio V.sub.T, which is a ratio of embossed depth relative to initial wall thickness, and wherein said area compression ratio falls within a range of 0.12 to 2.3 and said depth compression ratio falls within a range of 0.24 to 0.5.
A proces for the production of a raw sausage casing, which includes the steps of partially and permanently compressing a spun random fleece which has at least one polyamide and which contains no binding agent, forming an embossed surface on said fleece, and joining said fleece along its edges so as to form a tube including webs of uncompressed fleece and areas of compressed fleece to avoid disadvantages of fray encountered during unpeeling of the sausage casing, said partially and permanently compressing including an embossing by partial compression with said partial compression having an area compression ratio V.sub.F, which is a ratio of compressed fleece surface that represents area sum of all predetermined areas compressed by said embossing relative to the uncompressed fleece surface representing area sum of all webs and a depth compression area V.sub.T, which is a ratio of embossed depth relative to initial wall thickness, and wherein said ratio compression ratio falls within a range of 0.12 to 2.3 and said depth compression ratio falls within a range of 0.24 to 0.5.
