A reclosable zipper is disclosed which includes a first profile which has a first compressible foamed sealant layer, and a first interlocking element, which is unfoamed, extending from the first profile. The zipper includes a second profile which has a second compressible foamed sealant layer, and a second interlocking element, which is unfoamed, extending from the second profile. The rigidity of the interlocking elements provides the required stability when the zipper is closed while the foamed sealant layers improve the sealing characteristics of the zipper to a packaging film. |
