Abstract
An oxygen-absorbing container capable of forming active sites (polymer radicals) at any moment when it is desired to absorb oxygen remaining in the container and a method of producing packaged food using the container. A package capable of excellently preserving the content maintaining flavor can be easily produced through simple operation using an apparatus which is not so large in scale. The oxygen-absorbing plastic container has at least a portion that is made of a photo-oxidatively degradable resin or a resin composition containing a photo-oxidatively degradable resin and a photo-oxidation promoting agent that absorbs ultraviolet rays and visible light.
