Abstract: A bulk bag is provided with a seamless bottom or base. The base is constructed of a single sheet of material which is folded at the corners thereby providing a continuous and seamless member which prevents leakage of material contained within the bulk bag as well as contamination of product within the bulk bag from the environment. An upper assembly of the bulk bag may either conform to the shape of the base, or may be of another shape as desired.

Abstract: A bulk bag is provided which includes a base for cooperating with a forklift to allow transportation of the bag, and has a plurality of side walls extending upwardly from the base to collectively define a space for receiving bulk material. The base includes two spaced apart substantially horizontal engagement members for abutting support by respective forks or tines of the forklift and a reinforced cavity disposed between and downwardly extending from the engagement members for providing structural support to the bag. Reinforcing members extend across the inside of the bag from wall to wall adjacent the base. In one embodiment, the reinforcing members have openings to allow the bulk material to pass therethrough so that the reinforcing members become embedded therein and are under tension to maintain the bag in a desired configuration when filled. Alternatively, a plurality of reinforcing members, in the form of strips, are spaced apart and extend between the base walls within the bag.
