    摘要： A multilayered container comprising an intermediate layer of a resin composition (A) which comprises 50-95% by weight of a specific EVOH, and 50-5% by weight of an inorganic filler, and inner and outer layers of a moisture resistant thermoplastic resin (B), at least the body wall part of the container comprising multiplicity of regions in which substantially 2-dimensional thin layers of the inorganic filler extend parallel with the wall surface and laminated with each other, said layer of said resin composition (A) having a specific moisture permeability.
    The multilayered container can readily be prepared by thermoforming from the corresponding multilayered structure.
    Food packages obtained by filling the multilayered container of the present invention with food, sealing it and then sterilizing the package under a condition where heat and moisture act at the same time as in retorting are resistant against impermeation of oxygen that would deteriorate the food contained therein, thus exhibiting excellent storage capability, and have good container appearance.

    摘要： 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.
