Pinch Bottom Open Mouth Bag

The Pinch Bottom Open Mouth Bag is a popular industrial paper package designed to contain a variety of dry pourable products. The bag features seamless threading, minimal environmental impact, a secure seal, and prevents material caking. Open bags are loaded using a machine that dispenses material into the bag via a hopper or vertical filling nozzle. After the bag is filled, the pinch sealer activates and closes the bag by heating the air to activate the pre-coated adhesive on the bag opening. This folds the open end for a complete closure and pinches the fold until the adhesive sets. The bag can be supplied with either a stepped finish or a flat top.
