ABSTRACT:
The bags are produced on a form-fill seal machine operating horizontally or vertically. Zipper strips (16) are initially attached to a continuous web (12) which is subsequently formed into a continuous run of bags having end seals (20) and a back seal (18). The continuous run is separated into individual bags and the zipper strips finally attached to the bag walls by application of heat and/or pressure by a belt sealer (26) operating in a direction perpendicular to that of movement of the continuous web.
