Abstract
The disclosure relates to a zipper for a reclosable bag wherein the zipper is designed to make additional sound during operation, and further provide an increased tactile response. The zipper profile is manufactured by forming cuts in the profile, and then the profile is stretched so that the cuts become gaps. These gaps cause additional sound during operation of the zipper.
