Side Seam Gluing on a Tuber

When producing a multiwall bag on a tuber machine, one or more beads or ribbons of adhesive are applied to seal the bag into a tubular shape. Valco Melton expedites this process by providing cold glue valves capable of administering adhesive to paper layers in a continuous or high-speed intermittent fashion. We also provide hot melt valves to glue the bag’s inside film layer.
