The invention relates to food industry, in particular to production of sleeve casings, purposed for packing and storing food products of a pasty consistency, which are subjected to heat treatment, for example cooked sausages and melted cheeses. The sleeve casings for packing food products of pasty consistency includes outer and inner layers on the basis of polyamides, an intermediate layer of linear polyolefin or of copolymers thereof and two adhesive layers of polyolefin modified by a functional group, arranged on the both sides from the intermediate layer. The intermediate layer contains additionally a cyclic copolymer of polyolefin in an amount of 5-95 weight %. The outer layer contains an aliphatic polyamide, aromatic polyamide and a polyamide copolymer, and the inner layer contains an aliphatic polyamide and aromatic polyamide, as the polyamides or the outer and inner layers contain the polyamide copolymer as the polyamides.
