Abstract
A zipper for a recloseable bag provides a heat-settable portion for adhering the zipper to a polymeric bag at a temperature below that known in the art in order to prevent permanently sealing the bag closed inadvertantly. The zipper includes elongated base strips having flange portions for adhering the inner surface of the base strip to the outer surface of a polymeric bag. The base strip is adhered to the polymeric bag by a heat-setting compound coextruded, coated or laminated to the inner surface of the flange. The flange portions may be thinner than other portions of the base strips to permit the flange portions to be fused to the polymeric bag at a lower temperature than previously practiced.
