Claim Text:
1. A laminate comprising at least one layer of a first thermoplastic resin composition alternately stacked with at least two layers of a second thermoplastic resin composition so that the outermost layers are the layers of the second thermoplastic resin composition, wherein the first thermoplastic resin composition comprises at least one selected from the group consisting of ethylene-vinyl alcohol copolymer and modified ethylene-vinyl alcohol copolymers, and the second thermoplastic resin composition has a different composition from the first thermoplastic resin composition and comprises a brominated isoolefin-paraalkylstyrene copolymer rubber, and wherein, in any adjacent pair of the layer of the first thermoplastic resin composition and the layer of the second thermoplastic resin composition, the ratio E 1 /E 2 is more than 1 and up to 10, and the ratio t 1 /t 2 is 0.1 or more and up to 1, wherein E 1 and t 1 are the tensile modulus and thickness of the layer of the first thermoplastic resin composition and E 2 and t 2 are the tensile modulus and thickness of the layer of the second thermoplastic resin composition wherein the second thermoplastic resin composition comprises at least one thermoplastic resin selected from the group consisting of polyamide-based resins, polyvinyl alcohol, ethylene-vinyl alcohol copolymer, and modified ethylene-vinyl alcohol copolymers.
