摘要： The invention provides oxygen-absorbing resin compositions which are reduced in the quantity of by-product oxides and are excellent in oxygen-absorbing capacity, more specifically, an oxygen-absorbing resin composition which comprises a styrene resin, a thermoplastic resin having ethylene structure in the molecular structure, and a transition metal catalyst and in which the oxidation of the thermoplastic resin proceeds by the action of the styrene resin as a trigger to attain oxygen absorption, wherein the styrene resin comprises two kinds of styrene resins (A) and (B) different in styrene content and the styrene content of the resin (A) is higher than that of the resin (B); and an oxygen-absorbing resin composition comprising polyethylene, a resin other than polyethylene which is capable of acting as a trigger in the oxidation of polyethylene, and a transition metal catalyst, wherein the polyethylene comprises two or more kinds of polyethylenes and at least one of them is a linear low-density polyethylene obtained by copolymerizing ethylene with at least 4 wt % of a 1-alkene having 3 to 6 carbon atoms.
