Abstract
A reclosable zipper is provided having first and second opposing profiles forming at least one pair of opposing flanges. The flanges have cutouts, such as notches or apertures, disposed adjacent to side edges of the profiles so as to define at least one pair of cutouts. When the profiles are sealed to opposing inner surfaces of package panels, portions of the panels seal to each other through the at least one pair of cutouts, providing a reinforcing structure to opposing ends of the zippers, thereby preventing the zipper ends from separating upon opening the package.
