Abstract:
A reclosable zipper having a sealant applied thereon, for use in a polymeric bag. The reclosable zipper includes a first and second closure member, with each closure member having an interior surface and an exterior surface. A first sealant is present on the exterior surface of each of the first and second closure profiles; this sealant is used to attach a polymeric film that forms a bag body. A second sealant is present on the interior surface of each of the first and second closure profiles; this sealant enhances the seal between the closure profiles at the side edges of the bag.
Abstract:
A zipper closure for a polymeric package includes a plurality of profile members on a first polymeric surface, where one and not more than one of these plurality of profile members is colored differently from the remaining profile members on the same polymeric surface. The differently colored profile members provide a visual reference for properly orienting the zipper closure to the polymeric packaging during manufacture.
