<P>PROBLEM TO BE SOLVED: To provide a zipper tape with a cut tape, with which a packaging bag can be torn at a predetermined position easily when the bag is torn to be opened at an upper part of the zipper tape and a manufacturing process for it and the packaging bag with the zipper tape. <P>SOLUTION: A belt-like base 331 of a female member 33 of the zipper tape 3 attached to the inner face of the bag 2 has a broad section 34 formed in a broader shape than a belt-like base 321 of a male member 32 toward the opening part side of the bag 2. The cut tape 4 is arranged on the broad section 34 and a sealing layer 5 is laminated on the surface. The first protrusion 35 is formed on the broad section 34 and the second protrusion 36 is formed on the opening side end part 321A of the belt-like base 321. The cross sections of the protrusions are nearly trapezoid. When the zipper tape 3 is welded on the bag 2 and the bag is sealed with the sealing layer 5, vacant spaces are formed between the cut tape 4 and the first protrusion 35 and the second protrusion 36. <P>COPYRIGHT: (C)2008,JPO&INPIT |
