摘要
A tubular, seamless, water vapour permeable, smokable, biaxially draw-oriented and partially or completely heat-set food casing is provided having at least two layers based on thermoplastic polymers. At least one layer A, which does not form the inside layer, comprises a blend of aliphatic (co)polyamide and at least one hydrophilic polymer, while the inside layer I comprises a blend of aliphatic or isocyclic (co)polyamide and a block copolymer selected from polyether-amide, polyether-ester and polyether-urethane. The casing is produced by a tubular-film blowing process or a process with biaxial tubular-film draw-orientation. The casing is envisaged more particularly as synthetic sausage casing, especially for smoked raw sausage, such as salami.
