METHOD FOR PRODUCING BAG-SHAPED CONTAINER
Document Type and Number:
WIPO Patent Application WO/2010/007848
Kind Code:
A1
Abstract:
Film (1) formed into a tubular shape by inflation molding is collapsed flat and the opposite edges (1a, 1a) thereof are cut off along the feeding direction to obtain a base-material original fabric (2) consisting of two long film materials which are bonded tightly on the inner surfaces. The original fabric is rolled up to them use one film material as a protective layer (2a), and the other film material as an inner surface layer (2b), and an original fabric (3) for bag making is produced by laminating an outer layer material (2c) on the inner surface layer (2b). A bag is then made from the original fabric (3) for bag making while the protective layer (2a) is peeled such that the surface from which the protective layer (2a) is peeled is kept inside. When a bag-shaped container is produced using tubular film produced by inflation molding, the film can be rolled up without trouble even in the middle of the production process.
