    摘要： An improvement in a packaging multilayer plastic container comprising a gas-barrier interlayer of an ethylene/vinyl alcohol copolymer and an inner and an outer layer of a moisture-resistant thermoplastic resin such as a polyester sandwiching the interlayer. An intermediary layer comprising particles of a high water-absorbing resin dispersed in a resinous medium is provided between the gas-barrier layer and each of the inner and outer layers. Crosslinked polyacrylic acid or its salt or a vinyl alcohol/acrylic acid (salt) block copolymer, for example, may be used as the highly water-absorbing resin. Because of its high saturation moisture absorption at high temperatures, the highly water-absorbing resin is effective for preventing degradation of the gas-barrier property of the ethylene/vinyl alcohol copolymer during retorting.

    摘要： Disclosed is a coated oriented plastic vessel formed by subjecting a parison, preform or sheet comprising a molecularly orientable thermoplastic resin substrate and a coating layer of a vinylidene chloride copolymer formed on at least one surface of said substrate to a draw-molding operation such as biaxial draw-blow-molding or draw-forming, wherein the coating layer of the vinylidene chloride copolymer has such a molecular orientation tht the sum of two-dimensional orientation coefficients (l+m) in the axial direction and circumferential direction is at least 0.03 as measured according to the polarized light fluorometry and the coating layer is not substantially peeled at the low-temperature burst test conducted at -5.degree. C. This coated oriented plastic vessel is prepared by a process comprising coating an aqueous latex of a vinylidene chloride copolymer on at least one surface of a parison, preform or sheet composed of a molecularly orientable thermoplastic resin, drying the coated latex to form a coated structure and subjecting the coated structure to a draw-molding operation such as biaxial draw-blow-molding or draw-forming at a temperature higher than the glass transition temperature of the vinylidene chloride copolymer but lower than the melting point of the vinylidene chloride copolymer, at which temperature draw-molding of said thermoplastic resin is possible, to thereby from the coated structure into a shape of a vessel while drawing the coating layer.

    摘要： Disclosed is a process for the preparation of a coated plastic container, which comprises coating an aqueous latex or organic solvent solution of a vinylidene chloride copolymer on at least one surface of a plastic container formed by hot molding of a thermoplastic resin, drying the coating and crystallizing the coating simultaneously with or subsequently to the drying step.In the coated plastic container prepared according to this process, the adhesion of the coating layer of the vinylidene chloride copolymer to the plastic container substrate is highly improved, and even under severe conditions, peeling of the coating layer is prevented. Moreover, the gas barrier property, strength and chemical resistance of the container are prominently improved.
