Abstract: A bottom gusset bag includes a bottom gusset connecting a front and rear panel. The side regions of the front and rear panels are sealed to each other in a pair of side seams in a manner such that when the bag is unfilled it is flattened and when the bag is filled it is substantially a six-sided cubic shape with the bottom of the filled bag formed of the bottom gusset being substantially flat. The bottom gusset bag further includes a handle that includes a strip of material interior of the bottom gusset with the ends of the handle joined to each pair of side seams. Further, the bottom gusset bag can include weakened portions in the bottom gusset on opposing sides of the handle that, when broken, expose holes for a hand or fingers to enter the bottom gusset and wrap around the internal handle for carrying the bottom gusset bag with the bottom facing upwards.
