PURPOSE: To provide a multilayered structure having a membrane composed of a saponified ethylene/vinyl acetate copolymer (EVOB) excellent in gas barrier properties and transparency and extremely excellent in hot water resistance. CONSTITUTION: A multilayered structure is obtained by stretching a co-extrusion laminate having a layer composed of EVOH as an intermediate layer and both outer layers each having at least one polyolefin layer adjacent to the intermediate layer and a ratio (W/L) of the humidity permeability (W) (g/m<2> .day) at 40 deg.C and 90% RB of both outer layers and the thickness (L) (μm) of the intermediate layer is 8 or less. |
