PROBLEM TO BE SOLVED: To provide a multi-layer structure plastic container which includes an oxygen absorption barrier layer with an oxygen absorbent dispersed in oxygen barrier resin as an intermediate layer, and inner and outer layers formed of olefin resin, and continuously exerts oxygen absorption capacity of the oxygen absorbent in the oxygen absorption barrier layer over a long period of time, and maintains an excellent oxygen barrier property for a long period of time.SOLUTION: A plastic container has a multilayer structure formed of inner and outer layers 1, 3 of olefin resin, and an oxygen absorption barrier layer 7 arranged between the inner and outer layers 1, 3 through an adhesive layer 5. The oxygen absorption barrier layer 7 is formed of an oxygen absorption barrier resin composition with an oxygen absorbent dispersed in oxygen barrier resin, has a thickness of 15-40 μm. The oxygen absorption barrier resin composition has pellet oxygen absorption capacity of 0.05-1.2 cc/g day. |
