<p>An object of the invention is to provide a multilayered structure having very superior gas barrier properties and being excellent in flex resistance, pinhole resistance, stretchability, thermoformability and interlayer adhesiveness, and having superior durability enabling characteristics such as high gas barrier properties to be maintained even if used with deformation such as flexion and/or stretching, and to provide a laminate in which the multilayered structure is used, and a production method thereof. Provided by the present invention is a multilayered structure in which at least 4 resin-layers constituted with a resin composition containing an ethylene-vinyl alcohol copolymer are contiguously laminated. A single layer of the resin layer has an average thickness of preferably no less than 0.01 µm and no greater than 10 µm. The average thickness is preferably no less than 0.1 µm and no greater than 1,000 µm. When the content of ethylene units of the ethylene-vinyl alcohol copolymer is no less than 3 mol% and no greater than 70 mol%, the saponification degree is preferably no less than 80 mol%.</p> |
