Abstract:

A self-opening bag pack includes a plurality of stacked thermoplastic film bags, each of the bags have longitudinal side gussets and a U-shaped cut-out in an upper portion of the bag forming an open mouth portion and a pair of bag handles. The front and rear walls of each of said bags are corona treated to improve adhesion. An impact line is located immediately adjacent at least a portion of the U-shaped cutout and adheres the rear wall of a first bag in the bag pack to the front wall of a subsequent bag in the pack. Hanging apertures attach the bag pack to a dispensing rack. When the pack is attached to the rack and the first bag is pulled outwardly from the pack, the front wall of a subsequent bag will be adhered to the rear wall of the first bag, thereby causing the first bag to open.
