Abstract

Provided are a novel oxygen-absorbing resin composition not responsive to a metal detector, producing no odor after absorption of oxygen and having excellent oxygen-absorbing performance, and a multilayer body, container, injection-molded article and medical container using these. Further provided are an oxygen-absorbing resin composition etc. having excellent oxygen-absorbing performance in a wide range of humidity conditions from low humidity to high humidity. The oxygen-absorbing resin composition of the present invention is an oxygen-absorbing resin composition containing a polyamide compound and a transition metal catalyst, wherein the polyamide compound has at least one constituent unit having a tetralin ring. Moreover, the multilayer body, container, injection-molded article, medical container, etc. of the present invention are obtained by using the oxygen-absorbing resin composition of the present invention.
