Abstract
The disclosure relates to a reclosable zipper for a package or bag wherein apertures are formed at periodic package-width intervals passing through the interlocking elements of the zipper profiles in order to minimize the mass of zipper material in areas where side seals of packages or bags will be subsequently formed. The otherwise interlocking elements upstream of, or at the trailing edge of, the apertures are deformed so as to prevent interlocking of the elements through a limited area. This allows a separator pin to pass through the area of the apertures and pass between the zipper profiles, eliminating or reducing the collision of the separator with the zipper profiles and subsequent potential damage to the zipper profiles.
