LAMINATED FILM, PRODUCTION THEREOF AND BAG BODY USING THE SAME AND BAGGED-UP BODY

摘要

PROBLEM TO BE SOLVED: To produce a bag body having a double structure substantially consisting of an outer bag and an inner bag composed of a water-soluble film and excellent in the release characteristics of the outer bag. SOLUTION: A laminated film consists of a film for an outer layer, a water- soluble film 6 and the intermediate layer 5 interposed between the film 20 for the outer layer and the water-soluble film 6. At least the surface on the side of the water-soluble film of the intermediate layer contains high pressure polyethylene oxidized to a desired degree. The film 20 for the outer layer and the intermediate layer 5 are strongly bonded and the intermediate layer 5 and the water-soluble film 6 are directly brought to a contact state to be weakly bonded in a releasable manner.
