<P>PROBLEM TO BE SOLVED: To provide a plastic multilayer structure which is excellent remarkably in an oxygen permeation resistance and oxygen trapping properties and enables long-time preservation of food and a drink even when they are apt to deteriorate. <P>SOLUTION: The plastic multilayer structure has a layer constitution wherein a thermoplastic resin layer is disposed as inner and outer layers and a layer of a resin composition prepared by blending an oxygen absorber in a gas-barrier polyglycolic acid is disposed as a core layer, while an adhesive resin layer is disposed between the layers as occasion demands. In another mode, the plastic multilayer structure has a layer constitution wherein the thermoplastic resin layer is disposed as the inner and outer layers and the gas-barrier polyglycolic acid layer is disposed as the core layer, while an oxygen absorbing layer is disposed as intermediate layers and the adhesive resin layer is disposed between the layers as occasion demands. <P>COPYRIGHT: (C)2004,JPO |
