Abstract

An oxygen absorbing resin in which a deoxidizing composition is dispersed in a thermo-plastic resin mixture comprising (A) a thermoplastic elastomer and/or an ethylene propylene copolymer and (B) a thermo-plastic resin other than the above-mentioned (A), and having a flexural modulus of 600 MPa or less and an oxygen permeability of 130 cc.mm/m.sup.2.atm.day (23.degree. C., 50% RH) or more. The oxygen absorbing resin has an oxygen absorbing performance equal to that of a conventional deoxidizing agent in a small bag. A deoxidizing multi-layer structure which comprises a layer (I) comprising a thermoplastic resin layer having an oxygen permeability of 800 cc/m.sup.2.atm.day (23.degree. C., 50% RH) or more, a layer (II) comprising the oxygen absorbing resin, and a layer (III) having gas barrier properties. In addition, the deoxidizing multi-layer structure has a function of positively and efficiently absorbing oxygen.
