Provided are multilayered structures comprising at least 2 layers consisting of a layer of a composition (C) comprising 50 to 95 wt% of an ethylene-vinyl alcohol copolymer (A) and 50 to 5 wt% of a thermoplastic polyester (B) comprising at least 50 mol% of isophthalic acid base on the total moles of carboxylic acid component and 0.1 to 30 mol% of 1,3-bis(β-hydroxyethoxy)benzene and/or diethylene glycol based on the total moles of diol component, and a layer of a thermoplastic resin (D), said (A) and (D) satisfying the following relationship (I):
110°C ≧ X A - X D ≧ 0°C      (I)
wherein X A represents the melting point of A and X D represents the melting point or, in the case of no melting point, the softening temperature, of D. The multilayered structure does not cause, upon heat stretching, particularly upon high-speed heat stretching, to generate pinholes, cracks, irregularities, local thickness irregularities, and have excellent gas barrier property and its reliability.
