    Abstract: A composition comprising a matrix of an ethylene-vinyl alcohol copolymer having dispersed therein a granular drying agent in a particulate state, wherein the volume-area average diameter of the grains of drying agent having a long dia meter of not less than 10.mu. is not greater than 30.mu.. A multi-layer structure comprising layers of such a composition. The gas barrier property of the multi-layer structure is not substantially reduced after a retort treatment and thus, the multi-layer structure is extremely useful for packaging of food, especially packaging of retorted food.

    Abstract: Provided are resin compositions comprising:(A) 60 to 95% by weight of an ethylene-vinyl acetate copolymer having an ethylene content of 20 to 65 mol % and a saponification degree of vinyl acetate component of at least 96%,(B) 4.5 to 39.5% by weight of an ethylene-vinyl acetate copolymer having an ethylene content of 60 to 98 mol %, and(C) at least 0.5% by weight of a saponified product of an ethylene-vinyl acetate copolymer having an ethylene content of 68 to 98 mol % and a saponification degree of vinyl acetate component of at least 20%, the incorporation ratio of (C) based on the sum of (B) and(C) being not more than 38% by weight.The resin compositions of the present invention have markedly improved flexibility without deteriorating transparency and gas barrier properties as compared with conventional saponified products of ethylene-vinyl acetate copolymers. Multilayered structures comprising at least one layer of the composition have excellent resistance to falling shock, flexural resistance, prevention of air-back, skin-pack adaptability and shrink-packaging capability and can hence of great value for packaging various goods.

    Abstract: This invention provides a gas-barrier multilayered packaging material which comprises an outer layer of a composition comprising 55-97 wt % of an EVCOH and 45-3 wt % of a resin selected from the group consisting of polyamide, polyolefin, polyester and polycarbonate and an inner layer comprising a hydrophobic thermoplastic resin having a low moisture permeability; and further provides a gas-barrier multilayered packaging material which comprises an outer layer comprising a resin layer having a moisture permeability (measured at 40.degree. C., 90% RH) of at least 40 g/m.sup.2 day, an intermediate layer of a composition comprising 55 to 97% by weight of an EVOH and 45 to 3% by weight of a resin selected from the group consisting of polyamide, polyolefin, polyester and polycarbonate and an inner layer comprising a hydrophobic thermoplastic resin layer having a moisture permeability lower than that of the outer layer. Both of them are useful as packaging materials to be used for boil sterilization or retort sterilization.
