Patent ID: 7387837

Claim:
A multi-layered structure, wherein one of the layers of the multi-layer structure comprises a thermoplastic polyurethane composition comprising an ethylene-vinyl alcohol copolymer and/or a polyamide, and a thermoplastic polyurethane, wherein the retention of melt tension of said thermoplastic polyurethane composition, when kept in a molten state at 220° C. for 1 hour, is not less than 10% wherein said thermoplastic polyurethane composition is produced by melt kneading an ethylene-vinyl alcohol copolymer and/or polyamide, a thermoplastic polyurethane, and in addition an organic compound having a hydroxyl group and a molecular weight of not less than 50, wherein the organic compound having a hydroxyl group is used in an amount of from 0.5 to 20 parts by weight per a total weight of 100 parts by weight of the ethylene-vinyl alcohol copolymer, the polyamide and the thermoplastic polyurethane.
