U-Panel
U-Panel bags are constructed with three main body components – one that runs the full length of the bag forming the bottom and two sides (the “U”) and two additional pieces of fabric sewn between the U on two sides (the “Panel”). Generally, U-panel bags will maintain a square shape when filled, especially with the addition of internal baffles. U-panel bags are an industry standard and the most popular type of construction.

The U-shaped panel design is ideal for container bags and can achieve very high safe workload weight. The structure of the bag is a continuous "U" shaped panel that connects two opposite side walls.
