Circular bulk bags (FIBC) have a circular / tubular body that is a seamless, with only a top and bottom panel sewn into the bag. Circular style bags are ideal for fine and hydroscopic materials.
U-Panel bulk bags (FIBC) have one (1) continuous piece of fabric for a side, bottom, and opposite side panel creating a “U” shape. The remaining sides and top panel are then sewn in to construct the bag. U-Panel bags are an industry standard and provide a great mix of stack-ability, strength, and affordability.
