Abstract
A reclosable zipper for use with package, such as food and non-food packages, that include first and second mating profile members. Each of the first and second profile members of the zipper closure includes a pair of flanges each having a sealant layer. The sealant layer formed on each of the flanges protrudes past the outer surface of the flange such that the outer surface of the sealant layer contacts the film of web material. The sealant layer is formed from a material different than the material that forms the remaining portions of the first and second profile members such that the sealant layer melts and forms a bond with the web material upon the application of heat. Each of the profile members includes a standoff area formed along the inner surface of each flange to provide support for the flange during the application of the heating element.
