A bottom filled, top gusset plastic bag (10, 106) includes a pair of flexible ear handles (24, 26 or 130, 132). The handles include circular hand-receiving openings (76 or 134) and have circular outlines and circular transition regions (78, 80 or 136, 138) are provided between the ear handles (24, 2
A bottom filled, top gusset plastic bag (10, 106) includes a pair of flexible ear handles (24, 26 or 130, 132). The handles include circular hand-receiving openings (76 or 134) and have circular outlines and circular transition regions (78, 80 or 136, 138) are provided between the ear handles (24, 26 or 130, 132) and attached base portions of the handles. The circular hand-receiving openings (76 or 134) and the curved transition regions (78, 80 or 136, 138) function to distribute weight forces substantially across the full width of each side of a filled bag (10, 106).

A plastic bag, comprising: a bag of thermoplastic material including front and rear bag panels, a top gusset panel between the bag panels at one end of the bag, and fill opening at the opposite end of the bag, said bag panels having parallel side edges, and said top gusset panel having end edges colinear with and positioned between upper portions of the side edges of the bag panels when the bag is flat and unfilled, and having substantially parallel side edges; transverse seals connecting the side edges of the top gusset panel to the bag panels, and side seals connecting the side edges of the bag panels together, and further connecting the end edges of the top gusset panel together and to the upper portions of the side edges of the bag panels, in a manner resulting int he bag, when filled, assuming a substantially hexahedral shape and the top gusset panel forming a substantially closed top for the bag; said bag when filled having four sidewalls and corners were the sidewalls meet; handle panels of thermoplastic material, one on each side of the bag, said handle panels being one piece upper extensions of the front and rear bag panels, said handle panels having base portions contiguous to the side edges of the top gusset panel, and central ear handles extending from the base portions, said central ear handles being substantially identical in size and shape and including substantially circular hand-receiving openings; said base portions of the handle panels extending the full width of the front and rear bag panels; wherein in use the bag is filled through the fill opening and then the fill opening of the bag is sealed shut; and wherein when the filled bag is picked up by use of the handles upper stress boundaries are created in each handle panel, and said stress boundaries surround the hand-receiving openings at upper portions thereof and then extending downwardly and outwardly, towards the corners of the filled bag.
