PROBLEM TO BE SOLVED: To provide a packaging bag with a zip-fastener which improves appearance, facilitates the movement of a slider, reliably stops the slider at a sealing position, and prevents breakage of a bag body. SOLUTION: Male and female tracks of a sealing zip-fastener 5 with a slider 4 are mounted on a bulkhead partitioning seat 8, both ends of the bulkhead partitioning sheet 8 are heat-sealed together with both ends of front and back side sheets 2 and 3 of a bag body 1, and the partitioning sheet 8 with one track of the zip-fastener 5 mounted thereon is heat-sealed to one upper end of the front and back side sheets 2 and 3 of the bag body 1. The zip-fastener 5 is mounted on an opening part thereby. A content filling port 9 is formed between the partitioning sheet 8 with the other track mounted thereon and the front side sheet 2 or the back side sheet 3 of the bag body 1. A heat seal part 10 to cover a part of the filling port on the slider sealing position side is provided on an upper end of the bag body 1 in the content filling port 9. COPYRIGHT: (C)2005,JPO&NCIPI
