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: 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: A specific oxidation product layer is formed on the surface of a styrene resin container body, and via the oxidation product layer, a coated layer of a copolymer of vinylidene chloride, vinyl chloride and a (meth)acrylate is provided. This coated container has not only excellent gas-barrier property but also excellent peel resistance, particularly excellent peel resistance at low temperatures in the wet state.
