4-Panel

Economical Packaging - Thanks to increased bag capacity and reduced tare weight, more materials can be shipped at the same price. FBIC can also be placed and stacked higher and more efficiently than smaller bags. This maximizes shipping containers and storage space.

4-Panel bags are constructed with five main body components (4 side Panels + Base). When filled, a 4-Panel bag will hold its square shape similar to other construction types. Typically, 4-panel bags will hold their shape better than the U-panel bags, and U-panel bags will hold their shape better than a Circular bag. Due to the large amount of stitching required, a 4-Panel bag has a greater opportunity to fail at the seams and is prone to sifting. Nevertheless, 4-panel bags are ideal for storage due to the way they hold their shape when filled. 4-Panel baffled bags are very common bag style.

4-Panel bags maintain a square shape better than Circular or U-Panel bags. With the addition of internal baffles, this bag style offers fantastic stability and stackability functionality.
