ABSTRACT:
The present disclosure relates to a zipper for a reclosable package or bag and a method of forming thereof, wherein aligned apertures are cut into the zipper flanges proximate to the slider position when the package or bag is open. Portions of the front and rear walls of the package or bag extend through these apertures during the original manufacture of the bag, and are sealed to each other during the same sealing operation which seals the front and rear walls of the package or bag to the flanges of the zipper. The resulting seal between the front and rear walls, extending through the apertures in the zipper flanges, prevents the zipper profiles from opening in the portion where the slider is positioned when the reclosable package or bag is open.
