Abstract
A reclosable plastic pouch has a first elongated zipper member having a profile and a flange having a longitudinal perforation therein. The flange is above the profile and attached to one wall of the pouch above and below the perforation line and to the opposite wall of the pouch only above the perforation line. A mating profile is attached only to the opposite wall of the pouch below the perforation line. A notch at an edge of the pouch, aligned with the perforation line, facilitates the plastic to tear along the perforation line so that the portion of the pouch above the perforation line may be readily removed.
