DEOXIDIZING MULTILAYERED BODY AND METHOD OF MANUFACTURING THE SAME

摘要

The present invention is an oxygen absorbent which comprises a multilayered body with a plurality of thin resin layers laminated over one another, and at least one laminated side of this multilayered body is constructed as an oxygen-absorbing surface and, if there is a surface which is not an oxygen-absorbing surface, the multilayered body is constructed as having a gas-permeation-resistant layer on that surface. This multilayered body comprises: an oxygen-absorbing layer of a resin composition in which an oxygen-absorbing component is dispersed and which is made porous; a non-porous oxygen-permeable layer which is permeable to oxygen; and a porous oxygen-permeable layer which serves as a protection layer for the non-porous oxygen-permeable layer. On at least one side of said oxygen-absorbing layer, one or more non-porous oxygen-permeable layers and one or more porous oxygen-permeable layers are combined and laminated over one another, and the respective adjacent layers are thermally bonded to each other.
