ABSTRACT:
The invention provides self-opening polyethylene film bag stacks which do not require a separate adhesive layer between adjacent bags. The self-opening bag stack according to the invention preferably include a plurality of stacked t-shirt type high density polyethylene film bags releasably adhered together. At least an upper portion of the outer surface of the front and rear walls of each of the bags in the bag stack has been corona treated and at least one localized compressed area extends transversely through the bag stack in the upper portion of the bags such that the stack has a decreased thickness in the localized compressed area and so that adjacent outer wall corona treated surfaces defined by the localized compressed area are releasably adhered together.
