Abstract
An oxygen-absorbing film including at least, from an outer layer side, a surface substrate layer having an oxygen barrier property, an oxygen-absorbing resin layer, and an inner surface substrate layer that contains a stretched PET substrate and is heat-sealable. The surface substrate layer, the oxygen-absorbing resin layer, and the inner surface substrate layer are laminated in this order. The oxygen-absorbing film provides an oxygen-absorbing film suitable as a packaging material that excels in oxidation suppression of packaging contents and in non-sorption of aroma components and also exhibits excellent tearability.
Claims5
An oxygen-absorbing film comprising at least, from an outer layer side, a surface substrate layer having an oxygen barrier property, an oxygen-absorbing resin layer, and an inner surface substrate layer containing a stretched PET substrate, the inner surface substrate layer being heat-sealable, the surface substrate layer, the oxygen-absorbing resin layer, and the inner surface substrate layer being laminated in this order,
- wherein the inner surface substrate layer comprises the stretched PET substrate and a heat-sealable polyester-based resin layer, the heat-sealable polyester-based resin layer being laminated on an inner surface side of the stretched PET substrate.
