Abstract
A packaging material having an oxygen-absorbing layer of a thermoplastic resin which is blended with an organic oxidizing component and with a transition metal catalyst, wherein the thermoplastic resin is not substantially oxidized in the presence of the transition metal catalyst. The thermoplastic resin is not deteriorated by oxidation and, hence, oxygen-barrier property is not deteriorated, making it possible to stably suppress the permeation of oxygen over extended periods of time.
