ABSTRACT:
The present invention provides an oxygen-absorbing resin composition, which is capable of sufficiently causing the oxygen-absorbing reaction even in a low-water environment, and also provides a packing material, packing method and package using such oxygen-absorbing resin composition.
This invention is an oxygen-absorbing resin composition which contains a resin and an oxygen absorber which is made by coating iron powder with sodium iodide and potassium iodide. In a multi-layered film formed from this resin composition, iron particles coated with sodium iodide, etc. is dispersed in an oxygen-absorbing resin layer 4. Since a reaction accelerator of the oxygen absorber contains sodium iodide and potassium iodide as its principal component, this multi-layered film sufficiently absorbs oxygen in a low-water environment.
