    摘要: Disclosed is a function-separated composite vessel excellent in the easy openability, preservability and resistance to the deformation due to reduction of the pressure, which comprises a cup-shaped outer member composed of a paper substrate and a flexible seamless cup-shaped inner member composed of a gas-barrier plastic material, wherein the peripheral wall face of the inner member is substantially exactly fitted in the inner side of the outer member but is not bonded to the wall face of the outer member and an opening of the inner member is bonded to a curl portion or flange portion formed on an opening of the outer member.

    摘要: A method of preparing an antibacterial polymer and application of the antibacterial polymer obtained by this method. A silver oxide and a thermoplastic copolymer that contains a unit consisting of ethylenically unsaturated carboxylic acid or an anhydride thereof and that can be melted upon heating, are mixed, melted and is kneaded in order to obtain a polymer that exhibits in combination the antibacterial property and the heat-processability or the heat-moldability. By making this polymer present on the inner surface of the packing containers, it is made possible to impart the antibacterial property without deteriorating the flavor retentivity for the contents.

    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.
