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.

Abstract: A closure has at least one channel portion adapted to receive an interlocking profile portion. The channel has at least one window permitting visual inspection of a profile interlocked therein. At least one profile is disposed for interlocking with the channel and includes a stem joined to the closure and one or more latching projections formed by a frangible connection to the stem, wherein one or more projections are adapted to cooperatively interlock with the channel portion of the closure, thereby sealing the closure. In one closure, a tamper evident structure is included in the form of a slider having a shaver to engage in shaving contact with interlocking closure members when passed along the closure in a direction opposite to the closing direction. The various closure members can include different colors. The closures can be used on bag structures.
