Abstract
In a method for forming reclosable packages on a conventional form-fill-and-seal machine, a 'Y-type' zipper strip is fed toward and longitudinally down the filling spout thereof. A thermoplastic film is wrapped around the filling spout enclosing the zipper strip, and the lateral edges of the film are bonded together to form a longitudinal seam. The zipper strip webs are attached by sealing bars to the inside of the tube so formed from the thermoplastic film between the fill tube and the sealing bars. At intervals, transverse seams are formed to produce individual reclosable packages, which may also be separated from one another. The packages are filled with product during the course of their manufacture.
