The present invention is directed to 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 a multiplicity of regions in which substantially 2-dimensional thin layers of the inorganic filler extend parallel with the wall surface and are laminated with each other, said layer of said resin composition (A) having a specific moisture permeability. The multilayered container can be readily prepared by thermoforming the corresponding multilayered structure. The multilayered containers of the present invention are suitable for use as food packages. The multilayered container can be filled with food, sealed and then sterilized under conditions where heat and moisture act at the same time as in retorting. The packages thus obtained are resistant to oxygen impermeation that would deteriorate the food contained therein, and exhibit excellent storage capability, and have good container appearance.
