Definitions
- the present invention relates to a zipper tape and a container with the zipper tape.
- the manufacturing process of a bag with a zipper tape includes a side sealing process in which the films to which the zipper tape is bonded are opposed to each other, and portions corresponding to both ends of the bag are sealed together with the zipper tape.
