A zipper for closing the mouth of a bag that is formed by a groove on an internal face of tape, on one side, and a rib to be fitted to the groove on another internal face of the tape, on the other side. A bonding agent layer is provided on the outer side of the respective tapes and pastes a parting pattern paper on the outside of these bonding agent layers. This zipper, even if it is made of a substance which lacks heat sealing properties between the inner face of the bag and the zipper, can be attached easily to the inside mouth of the bag by pasting up the bonding agent covered by the parting pattern paper, to the inner face of mouth of the bag, by stripping the said parting pattern paper.
