A method and apparatus for manufacturing reclosable bags having slide zippers on a form-fill-seal (FFS) machine is provided. In a first embodiment a coil of sliders is fed to an insertor mechanism for applying the slider downstream of a coil of zipper. In a second embodiment a magazine of individual or connected sliders is used to feed the slider insertor mechanism. In a third embodiment bulk sliders are introduced into a vibratory feeding bowl which then orients and feeds the sliders to the slider insertor mechanism. The slider insertor mechanism may be upstream of the FFS machine or at the FFS machine upstream or downstream of the sealing bars used to seal the zipper the bag film. The zipper flanges may be provided with a peel seal layer to provide a hermetic and/or tamper evident seal for the bag.
