LAMINATED FILM AND PACKAGE

WIPO Patent Application WO/2012/008165

A1

Provided is a laminated film with excellent oxygen absorbing ability. The laminated film (100) is provided with an oxygen-absorbing layer (150), a first adjacent layer (140), and a second adjacent layer (160). The oxygen-absorbing layer (150) contains an oxygen absorber and an oxygen absorption reaction catalyst. The first adjacent layer (140) is laminated in contact with one of the surfaces of the oxygen-absorbing layer (150). The second adjacent layer (160) is laminated in contact with the other surface of the oxygen-absorbing layer (150). The content of the oxygen absorption reaction catalyst is between 100 ppm and 5000 ppm in terms of the weight ratio with respect to the oxygen-absorbing layer (150). The total content of an oxidation inhibitor of the first adjacent layer (140) and an oxidation inhibitor of the second adjacent layer (160) is 800 ppm or less in terms of the weight ratio with respect to the total amount of the two abovementioned layers (the first adjacent layer (140) and the second adjacent layer (160)).
