The present invention relates to an at least 4-layer coextruded, biaxially stretched, tubular seamless scalded and cooked sausage casing with improved tear-open characteristics in the filled state, combined with a reduced tendency to burst when the sausage product is cut, containing at least two layers predominantly made of aliphatic polyamide, which form the inside - Form and outer hose surfaces, and at least two further layers, which are enclosed by the inner and outer polyamide layers, wherein at least one of the enclosed layers acts as a water vapor barrier and has a polyolefinic character and at least one further of the enclosed layers has a high oxygen-blocking effect and predominantly consists of Ethylene vinyl alcohol copolymers, characterized in that the quotient of the tear resistance in the transverse direction and the tear resistance in the longitudinal direction between 0, 65 and 0.85, the degree of surface stretching of the film product being between 8 and 11. |
