Transparent gas-barrier multilayer structure.

摘要

A transparent gas-barrier multilayer structure comprising (A) at least one layer of a polyamide composition comprising (a) 30 to 80 parts by weight of a first copolyamide composed of an aromatic dicarboxylic acid as a main acid component and an aliphatic diamine as a main diamine component and (b) 70 to 20 parts by weight of a second copolyamide composed of an aliphatic dicarboxylic acid as a main acid component and m-xylylenediamine as a main diamine component, the total amount of the first copolyamide and the second copolyamide being 100 parts by weight, and (B) at least one layer of a thermoplastic resin other than the polyamide composition, said at least one layer (A) being bonded to said at least one layer (B).
