Disclosed are methods of making slide-zippered reclosable packages on horizontal form-fill-seal (HFFS) machines and horizontal form-vertical-fill-seal (HVFS) machines. In an embodiment of the present invention, a chain of packages is formed, filled and sealed on an HFFS machine or the like. A pair of opposing film extensions are provided on each package. As the chain of packages is indexed forwardly, a reclosable zipper is inserted between the film extensions of the leading package and sealed thereto. A slider is then inserted on to the reclosable zipper of the leading package and the completed leading package is cut from the chain. In a second embodiment packages having reclosable zippers are output from an HFFS machine or the like, either individually or in a chain. A slider is then inserted on to the zipper of each package in turn. Still further in a third embodiment packages are formed, filled and sealed on an HFFS machine or the like. During package formation, a reclosable zipper is sealed to each package and then a slider is inserted on to the zipper. Still further, in a fourth embodiment packages are formed, filled and sealed on horizontal form-vertical fill-seal (HVFS) machine or the like. During package formation, a reclosable zipper is sealed to each package and a slider is inserted on to each zipper, either before or after zipper sealing.
