A bulk bag for dense materials includes side walls seamed together end-to-end to form a rectangular enclosure and at least a bottom wall secured to the lower ends of the side walls. Baffles are secured in the side wall seams and extend diagonally across the interior of the bulk bag to maintain the bulk bag in a rectangular cross-sectional configuration when filled with dense materials.

1. A bulk bag for dense materials comprising: four side panels each having atop, a bottom, and opposed ends; the four side panels being seamed together end to end to define a rectangular enclosure characterized by four corners; a bottom wall seamed to the bottoms of the side panels; two baffle segments each comprising two baffle portions and each having opposed ends and a centerline; the opposed ends of each baffle segment being secured to adjacent ends of two side panels; the midpoints of the two baffle segments being seamed together at the centerline; and apertures formed through the baffle segments to facilitate the distribution of dense materials within the bulk bag. 2. The bulk bag for dense materials according to claim 1 wherein the four side panels are characterized by a predetermined height comprising the distance from the bottom wall to the tops of the side walls, and wherein the baffle segments are characterized by a predetermined height which is substantially equal to the predetermined height of the side walls. 3. A bulk bag for dense materials comprising: four side panels each formed from woven fabric; the four side panels being seamed together end to end to define a rectangular enclosure characterized by four corners; the rectangular enclosure being further characterized by a centerline extending parallel to the side panels and located equidistant from each of the four corners; two baffle segments each comprising two baffle portions and each having opposed ends and a midpoint; the opposed ends of each baffle segment being secured to the ends of two side panels of the bulk bags; the midpoints of the two baffle segments being seamed together at the centerline; and apertures formed through the baffle segments to facilitate the distribution of dense materials within the bulk bag. 4. The bulk bag for dense materials according to claim 3 wherein the four side panels are characterized by a predetermined height comprising the distance from the bottom wall to the tops of the side panels, and wherein the baffle segments are characterized by a predetermined height which is substantially equal to the predetermined height of the side panels. 5. The bulk bag for dense materials according to claim 4 further including additional baffles extending across the corners of the bulk bag. 6. A bulk bag for dense materials comprising: four side panels each formed from woven fabric and each having a top, bottom, and opposed ends; the four side panels being seamed together end to end to form a rectangular enclosure characterized by four corners; the rectangular enclosure being further characterized by a centerline extending parallel to the side walls and located equidistant from the four corners; a bottom wall formed from woven fabric and seamed to the bottoms of the side walls; two baffle segments formed from woven fabric and having opposed ends; one of the baffle segments having its opposed ends secured to the ends of the first, second, and third side panels and extending inwardly therefrom to the centerline; the other baffle segment having its opposed ends secured to the ends of the third, fourth, and first side panels and extending inwardly therefrom to the centerline; the baffle segments being seamed together along the centerline; each of the baffle segments comprising two baffle portions, the baffle portions each extending inwardly from one of the sides of the rectangular enclosure to the centerline, and wherein each of the baffle portions has at least one aperture formed therethrough to facilitate the flow of dense materials within the bulk bag. 7. The bulk bag according to claim 6 wherein each of the four side panels is characterized by the same predetermined height, and wherein each of the baffle segments is characterized by a predetermined height which is substantially identical to the predetermined height of the side walls.
