Abstract

A method of making a recloseable package having a slider zipper assembly includes advancing a web of a plastic film material in a direction along a longitudinal axis thereof, and applying a plurality of profile strip fastener assemblies to the plastic film material transversely of the longitudinal axis. A slider is applied to each of the fastener assemblies so that movement of each slider along the length of the respective one of the fastener assemblies moves the pair of profile strips thereof into and out of interlocking engagement. Opposite side edges of the plastic film material are joined to form a tube, with seals formed transversely of the tube to form a top seal and a bottom seal for each of the packages. The package is configured such that the slider projects generally through the front wall of the package, with the front wall optionally being provided with a frangible region in the form of a line of weakness aligned with the fastener assembly. Initial opening movement of the slider acts to fracture the frangible region for tamper-evidence.
