Laminated film, method for production thereof, bag and package using the laminated film, and method for separation thereof |
摘要 |
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.
