U-Panel jumbo bags are engineered using a primary polypropylene fabric panel that forms the entire bottom and two adjoining side walls, creating a seamless U-shaped body. To complete the structure, two separate side panels are stitched to the remaining open sides.
This construction method delivers excellent load stability, durability, and shape integrity during filling, stacking, and transport—making U-Panel bags one of the most reliable designs for general bulk materials.
