ABSTRACT:
A bag and dispensing system system wherein the thermoplastic bag to be dispensed may be retained in an open position, to allow for the loading thereof with contents for carrying, such as purchased goods or the like. The system is further configured such that the loaded bag, when dispensed, draws the next bag in the stack forward into an open loading position such that it is ready to be loaded with goods without further manipulation by the attendant. The preferred embodiment of the present invention teaches the utilization multi-edged penetration punch applied to the handle area of the bags to hold said handles together for handling of the bag pack, and for facilitating opening of the next bag in the stack on the rack, when a loaded bag is removed. The preferred embodiment of the present invention utilizes co-extruded film, wherein there is provided a high density film having bonded thereto a lower density film of lesser density than said high density film, such that said lower density film forms the exterior side of said co-extruded film. The co-extruded film is then corona treated at a higher energy level than that recommended for facilitating a printing surface on said film. Said film is then die-cut to form bag stacks, and simultaneously punched with the multi-faceted punch in the area of the handles. This punch penetrates the film forming the bag walls, melding the adjacent walls together in a releasable fashion, allowing self opening of said bags.
