Abstract

Oxygen-absorbing resin composition, not responsive to a metal detector, producing no odor after absorption of oxygen and has excellent oxygen-absorbing performance in a wide range of humidity conditions from low to high humidity. An oxygen-absorbing molded article, and a multilayer body, container, injection-molded article and medical containers also provided. The oxygen absorbing resin composition contains a polyester, comprising at least one constituent unit having a tetralin ring component compound, a transition metal catalyst, and a catalyst for producing the polyester. The oxygen-absorbing molded article of the present invention can be formed by molding the oxygen-absorbing resin composition into a film or a sheet. The multilayer body, container, injection-molded article, medical container, etc. of the present invention are obtained by using the oxygen-absorbing resin composition.
