  • Laminated film and packaging container
    Patent number: 10392179
    Abstract: A laminated film including: an inner layer which is formed of a linear low density polyethylene resin and is heat-sealable; an outer layer which is laminated on the inner layer; a fragile processed portion which is formed by laser irradiation to the outer layer and has a depth reaching at least an inside of the outer layer and not penetrating the inner layer; and an intermediate layer which is provided between the inner layer and the outer layer, wherein the intermediate layer is an ink layer for reducing a lamination strength between the inner layer and the outer layer, and is formed in a region excluding the fragile processed portion and excluding a periphery of the fragile processed portion in planar view.
