METHOD FOR PRODUCING CONTAINER MADE OF SYNTHETIC RESIN FILM

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a container made of a synthetic resin film which is easy of handling by folding a polyethylene resin tube body flatly and heat-sealing it. SOLUTION: The polyethylene resin tube body 11 is used. Nonheat-welding thin film layers 14 and 14 are set on the outer surfaces of trough-folding parts 12c and 13c forming the right and left side parts 12 and 13, so that the outer surfaces of the side parts 12 and 13 are prevented from being heat-welded. The container 1 made of the synthetic resin film is produced by one heat-sealing process. COPYRIGHT: (C)2005,JPO&NCIPI
