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 type of square FIBC.

Baffled bulk bags are designed to be stackable and maintain their shape, which makes it suitable for limited space. They are constructed with baffles sewn into the corners that prevent expansion while allowing product to flow through the bag.
