- These overlapping portions 205 and 206 constitute the free ends 20A and 20B of the back side flap 20, respectively.
- the overlapping portions 205 and 206 formed in the second folding step S20 are not joined to the flap sheet 200.
- the fastening tapes 41 and 42 are attached to the flap sheet 200 at predetermined intervals in the machine direction MD.
- the fastening tapes 41 and 42 are an integral member (also referred to herein as a fastening tape 40).
- the fastening tape 40 is processed, at its center, to have a perforation line 45 or the like in the machine direction MD that facilitates separation.
