METHOD AND APPARATUS FOR FORMING RE-CLOSABLE PACKAGE AND PACKAGE PRODUCED BY THE METHOD

摘要

PROBLEM TO BE SOLVED: To fit a slider to a zipper in the production process of a package produced by a molding/packing/fusion-bonding machine. SOLUTION: A tube is molded by advancing a film material 22 for forming the package in the longitudinal direction while both longitudinal fringes of the film material 22 are guided to be formed in a fin shape. The zipper 38 is supplied into a fin by the first guide 50 arranged to adjoin the fin, and the flange of the zipper 38 is supplied along both sides of the second guide 54. The flange is fusion-bonded to the side opposite to the second guide 54 of the fin. Engagement members are mutually pressed at a distance corresponding to the length of the package, and the slider is fitted to the engagement members between adjacent pairs in the pressed parts.
