ABSTRACT:
An expandable plastic film gusseted bag is utilized. As in conventional bag manufacture, each front gusset panel is connected to a rear gusset panel and each of the gusset panels is foldable between the front panel and the rear panel to provide a continuous bag periphery. A bottom joins the bottom of the front panel, rear panel, two rear gusset panels and two front gusset panels at substantial right angles to the side edges of the front panel, rear panel and gusset panels to close the bottom of the bag and leave only the top open. The improvement provides each plastic bag with eight first linear folding axes, each configured adjacent the bottom and within one of the front panel, each front gusset panel, the rear panel and each rear gusset panel. These folding axes extend from a joinder of a gusset at the bottom to the side edges of the front panel or the rear panel and the front gusset panel or the rear gusset panel at an approximate 45.degree. angle. The folding axes are made by a process from to a group consisting of either a cold seal or a hinge in the plastic film while the film is planar. On opening of the expandable gusseted bag, the bottom seal of the bag is disposed adjacent the gussets and forms a generally triangular shaped overlay relative to the gussets to form a flat bottom bag.
