Zusammenfassung:Reclosable bags (10) are disclosed wherein a sheet of web (100) is folded so that outward longitudinal quarters are folded over a central longitudinal half in a horizontal form fill seal apparatus (1000). The central longitudinal half forms the back wall of the bag (10) while the two outward longitudinal quarters form the front wall of the bag. A fin seal (24) is formed where the longitudinal edges meet. The zipper (30) is formed within the fin seal. However, in an alternative embodiment, the zipper is formed within the top fold while the longitudinal edges are joined by a fin seal.
