Abstract
Provided is a novel oxygen-absorbing resin composition having excellent oxygen-absorbing performance and suppressing odor generation after absorption of oxygen even if a material responsive to a metal detector is not used. Further provided is an oxygen-absorbing resin composition having excellent oxygen-absorbing performance in a wide range of humidity conditions from low humidity to high humidity. Such an oxygen-absorbing resin composition contains a copolymerized polyolefin compound and a transition metal catalyst, in which the copolymerized polyolefin compound contains at least one constituent unit having a tetralin ring.
