Internal fabric panels (baffles) are sewn across the four corners of the bag. When filled, these baffles allow the material to flow into the corners while preventing the bag from bulging outward into a round shape. It stays square, saving valuable space on trucks and in warehouses.

A large, skirt-like fabric extension (or top skirt) at the mouth of the bag. It provides a wide-open top for fast, easy filling, and it features an integrated tie string or cord to securely cinch the top shut after filling. A narrow, cylindrical fabric tube (discharge chute) at the base of the bag. It allows for controlled, clean, and dust-minimized emptying or discharging of the contents into bins, mixers, or processing equipment by simply untying a cord.
