摘要: An oxygen-absorbing material including a transition metal compound and one or more thermoplastic resins, when used for a molded product such as container, exhibits excellent gas-barrier and oxygen-absorbing properties. The material absorbs oxygen from contents and blocks oxygen from entering so that the contents can be maintained in an oxygen-free state for a long period of time. An excellent oxygen-absorbing property is achieved by an amino group content of 20 mmol/kg or lower in at least one thermoplastic resin and by lowering the crystallinity of the thermoplastic resin.
