Abstract
The use of coextruded or integral sealing ribs on zipper flanges enhances the quality of the sealing between the flanges and the walls of a reclosable package. The coextruded sealing ribs may be made from sealing resins or similar materials. Additionally, grip strips are placed on the opposite side of the flanges from the ribs in order to improve the quality of the sealing even further and to inhibit inner flange sealing.
