Oxygen-absorbing resin compositions, oxygen-absorbing film, and oxygen-absorbing multilayer structure

The invention provides an oxygen absorption resin composition with the advantages of excellent oxygen absorption function, less metal content and less smell while absorbing oxygen under the room temperature. The oxygen absorption resin composition comprises an oxygen absorption film of the oxygen absorption resin composition and an oxygen absorption multiple layer structure containing the oxygen absorption resin composition. One oxygen absorption resin composition comprises a resin (A1) having a C-H bond with dissociation energy below 3.70eV and a resin (B1) having a C-H bond with dissociation energy between 3.70eV and 4.20eV. The other oxygen absorption resin composition comprises a resin (A2) having a C-H bond capable of generating the carbon free radical whose reaction energy with oxygen below 10.0cal/mol and a resin (B2) having a C-H bond capable of generating the carbon free radical whose reaction energy with oxygen beteeen 10.0cal/mol and 22.0cal/mol.
