Tunnel Loop Bags are FIBCs (Flexible Intermediate Bulk Containers) with two continuous side tunnels instead of standard lifting loops. A forklift’s tines slide directly through the tunnels, making the process faster, safer, and more efficient. This design allows a single operator to lift, position, and unload the bag without needing assistance. It also helps reduce pallet usage and labor time, especially in facilities where frequent bag handling is required.
Tunnel Loop Bags are commonly used in industries that handle bulk or heavy materials requiring quick movement and precise positioning, including:
