ABSTRACT:
A multi-layered tubular synthetic sausage casing which includes an outer polyamide layer, an inner polyolefin layer and an intermediate layer for mutually bonding the inner and outer layers. The inner polyolefin layer includes a copolymer comprised of units of ethylene, propylene or straight-chain alpha-olefins having 4 to 8 carbon atoms, or of a mixture of these copolymers. In a preferred embodiment, the polyolefin layer is comprised of an ethylene/propylene/butylene terpolymer and/or of a propylene/butylene copolymer.
