    摘要: The oxygen-absorbing package of the present invention is produced by packaging an oxygen-absorbing composition comprising, as an effective component, an iron powder containing a fine iron powder passing through a 200-mesh standard sieve in an amount of 5% by weight or less by an air-permeable packaging material using an automatic filling-packaging machine. By using the above oxygen-absorbing composition, the iron powder is prevented from being partially scattered to attach to the outer surface of the oxygen-absorbing package during the industrial packaging operation using the automatic filling-packaging machine of high productivity, thereby enabling to obtain an oxygen-absorbing package capable of preserving products for a long period of time without contamination and color change during the storage.

    摘要: 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.
