Title:
OXYGEN-ABSORBING RESIN COMPOSITION, OXYGEN-ABSORBING MOLDED BODY USING SAME, AND MULTILAYER BODY, CONTAINER, INJECTION MOLDED BODY AND MEDICAL CONTAINER EACH USING OXYGEN-ABSORBING RESIN COMPOSITION OR OXYGEN-ABSORBING MOLDED BODY
Document Type and Number:
WIPO Patent Application WO/2013/077436
Kind Code:
A1
Abstract:
Provided are: a novel oxygen-absorbing resin composition which is not sensitive to metal detectors, does not generate an odor after the absorption of oxygen and exhibits excellent oxygen absorption performance; an oxygen-absorbing molded body which uses this oxygen-absorbing resin composition; and a multilayer body, a container, an injection molded body, a medical container and the like, each of which uses the oxygen-absorbing resin composition or the oxygen-absorbing molded body. Also provided are: an oxygen-absorbing resin composition which exhibits excellent oxygen absorption performance over a wide range of humidity conditions from low humidity to high humidity; and the like. An oxygen-absorbing resin composition of the present invention contains a polyester compound and a transition metal catalyst, and the polyester compound contains at least one constituent unit that has a tetralin ring. An oxygen-absorbing molded body of the present invention is obtained by molding the oxygen-absorbing resin composition into a film form or a sheet form. A multilayer body, container, injection molded body, medical container and the like of the present invention are obtained using the oxygen-absorbing resin composition of the present invention.
