Abstract: A stack of a plurality of headerless plastic bags are assembled together for individual dispensing. Each bag comprises a front wall having a first body portion and a first lip and a rear wall attached to the front wall. The rear wall includes a second body portion which overlies the first body portion of the front wall and a rear lip which extends beyond the front lip of the front wall. The bags are collated into a stack and are removably joined to one another by forming a cold weld in and between the rear lips of the rear wall of adjacent bags. The cold welds are formed by pressing the rear lips of the bags together under pressure, but without the application of heat. The cold welds join the plurality of bags in the stack together until the cold welds which join a particular bag to the stack are severed. Each bag is dispensed in its entirety without any residual waste.
