Abstract (en)
A bag bundle (10) comprises a plurality of plastic bags (12). Each such bag (12) includes a first sidewall (14), a second sidewall (16) integral with the first sidewall (14) at lateral end portions thereof, a closed bottom (18), an opening (20) in distal relations to the bottom (18) and a tab (24). A longitudinal end portion of the first and second sidewalls (14, 16) defines the opening (20). The tab (24) is integral with at least one of the first and second sidewall end portions adjacent the opening (20). The tab (24), moreover, is readily separable from such sidewall end portion becaus e of the presence of a plurality of perforations formed in such sidewall end portion (26) adjacent the opening (20). Only one of the first and second sidewalls (14, 16) includes a hand hole (28) formed through such sidewall. The hand hole (28) has a thickened, reinforcing edge (25) in a front sidewall and the tab (24) is attached only to the back sidewall. The bags (12) are affixed together at their tabs (24) in a stacked, folded manner, all such bag hand holes (28) being uniformly disposed. The affixed tabs (24) preferably include at least one support hole (32) therethrough for securing the bag bundle (10) to a support (34, 36). Also disclosed are methods and apparatus for manufacturing the bag bundles (10).
