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.
