Abstract (en)
Since a rib (47) having a thickness (D) substantially equal to a thickness (D2) of each of first and second thick portions (45A, 45B) is provided in a cutting portion (44) of a zipper tape, the first and second thick portions (45A, 45B) and the rib (47) can be bonded to an inner surface (211A) when the zipper tape is bonded to a bag body. Accordingly, when tearing a packaging bag (1) for opening, stress concentrates on a thin portion (46) having a small tensile strength, so that the packaging bag (1) can be cut at a single cutting position in the thin portion (46). Consequently, no cutting fragment is generated. Moreover, since a cutting line is positioned by the rib (47) when tearing the packaging bag (1), the cutting line is not waved, so that the packaging bag (1) can easily be torn with a linear cutting performance.
