Abstract:
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 wherein, in any adjacent pair of the layer of the first thermoplastic resin composition and the layer of the second thermoplastic resin composition, the layer of the first thermoplastic resin composition and the layer of the second thermoplastic resin composition have a specific tensile modulus ratio and a specific thickness ratio.
