Provided are an oxygen-absorbing resin composition, which is excellent in an oxygen absorbing property, absorbs the oxygen remaining in a container after sealing and secures good preservability for the contents in a container, and further is improved in formability, the dispersibility of an oxygen-absorbing agent, the stability of an oxygen-absorbing capability, the performance capability for the prevention of the exfoliation or separation of an oxygen-absorbing agent from a base resin, the lowering of the sealing property of a sealing section, and the like, which are problems in the case of using a conventional resin composition containing an oxygen-absorbing agent having high oxygen absorbability, but low compatibility with a base resin; and an oxygen absorbing container cap and an oxygen absorbing container stopper portion using the resin composition. The oxygen-absorbing resin composition is characterized in that it comprises a base resin and an oxygen absorbing agent containing particles having a size of 1000 μm or less in an amount of 20 % or more which is dispersed in the base resin in amount of 20 % or less relative to the base resin. |
