ABSTRACT:
A laminated film includes an outer-layer-film, a water-soluble film, and an intermediate layer interposed between the outer-layer-film and the water-soluble film. The intermediate layer contains high-pressure polyethylene oxidized to a prescribed degree on a surface thereof contiguous to the water-soluble film. The outer-layer-film and the intermediate layer adhere fast to each other. The intermediate layer and the water-soluble film directly contact each other and adhere so weakly to each other as to be peelable. The water-soluble film includes a water-soluble substrative film and water-soluble anchor coating agent distributed on a surface of the water-soluble substrative film contiguous to said intermediate layer.
