There are 3 basic types of bulk bag constructions: U-Panel, 4-Panel, and Circular/Tubular. Baffles are an internal component that can be added to each construction to create a “baffled” bag. More specifically, baffles are fabric panels or strings sewn inside each of the bag’s four corners that allow a bag to maintain a square shape when filled.

Baffled, Formstable, and Q Bag are all terms for the same square FIBC.

Without a baffle, a standard bulk bag bulges on the side or belly when full. Baffled bags are ideal for their stability and stackability. They also increase overall storage capacity. The most common type of baffle bag is the 4-panel baffle bag.
