<p><P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a packaging bag with a zipper tape, manufactured easily without generating a wrinkle and defective adhesion. <P>SOLUTION: A zipper tape member 311 having male side meshing parts and female side meshing parts on one face of a long band-like tape is drawn out to punch and remove portions of the male side meshing parts and the female side meshing parts at a prescribed interval. The zipper tape member 311 is cut between the male side meshing parts and the female side meshing parts by the cutting member 331 to be separated into a male side band-like member 21 and a female side band-like member 22. The male side band-like member 21 and the female side band-like member 22 are heat-sealed onto a film 10 to form the packaging bag 1 by a bag manufacturing device 35. Thereby, a length difference and a tension difference are hardly generated in the male side band-like member 21 and the female side band-like member 22, and the wrinkle and the defective adhesion are prevented from being generated when heat-sealing the zipper tape 2. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
