摘要:
The oxygen-absorbing label of the present invention has a laminated structure successively comprising a base layer having a release adhesive layer on its surface, an oxygen-absorbing sheet made from an oxygen-absorbing resin comprising a thermoplastic resin and an oxygen absorbent blended therein, and an air-permeable layer. The air-permeable layer is bonded to the base layer at a position surrounding an outer periphery of the oxygen-absorbing sheet. The air-permeable layer comprises (A) a water-resistant moisture-permeable resin film having a water pressure resistance of 2,000 mmH2O or higher and a moisture permeability of 1,000 g/m2/24 h or higher and (B) a microporous film.
