There is disclosed an oxygen-absorbing multi-layer film which comprises an outer layer comprising a thermoplastic resin; an adhesive layer comprising an epoxy resin; an oxygen-absorbing layer comprising a thermoplastic resin and an iron based oxygen-absorbing agent incorporated therein; and a heat sealing layer comprising an oxygen-permeable thermoplastic resin, wherein the adhesive layer comprises a gas barrier epoxy resin composition containing at least 30% by weight, preferably 40 to 90% by weight of a xylylenediamine unit (N—CH 2 —C 6 H 4 —CH 2 —N). The multi-layer film preferably having an overall thickness of at most 120 micron is excellent in oxygen-absorbing function, gas barrier properties, impact resistance, film rigidity and economical efficiency, and is well suited for use as packaging materials for food, pharmaceutical and the like. |
