A zip fastener chain comprised of a pair of stringer tapes of substantially endless length each having along their longitudinal edges alternate groups of fastener elements and element-free selvage portions. The groups of fastener elements are interconnected by a strip of water-soluble film, the arrangement being such that there may be provided a space or element-free portion on an individual fastener without having to remove those fastener elements off the tapes as in conventional practice. |
