Abstract
The oxygen absorptive resin composition of the present invention includes: a thermoplastic resin (a) having carbon-carbon double bonds; a gas barrier resin (b) having an oxygen transmission rate of 500 ml·20 μm/m·day·atm or less (20° C. 65% RH); and a transition metal salt (c). This resin composition and molded articles formed using the resin composition effectively absorb and scavenge oxygen when used to package products susceptible to degradation by oxygen, such as foods and drinks.
