Abstract
Straight zipper sections are attached to a carrier tape for attachment to the mouth end of a bag. The straight zipper sections are mounted on the continuous tape in longitudinal series orientation, or in spaced side-by-side orientation across the length of the tape. The tape in either case may be fan folded and packed into a storage or shipping container. The tape provides for closing attachment across the mouth of a bag to provide a security membrane and/or a tamper evident structure required to be ruptured to gain initial access into the bag after the zipper is opened.
