U-panel and Tubular / Circular bulk bags are 2 type of FIBC bags. Their structural, benefit and kind of product would be carried by each type can be NOT similar. So what are the difference between them ? Let’s find out more with us.
1. Structure of U-panel bags and Circular bulk bags?
U-Panel bags are made of three pieces of fabric with one continuous piece forming one side, the bottom and the opposite side. The two other sides are then sewn on.
The Circular bag/ Tubular bags is made of only two pieces, consisting of a seamless cylindrical tube and the bottom piece, which is sewn on.

2. Benefit of each type bags.
In the U-Panel bags the bottom and two of the sides are all one piece of fabric, which distributes the weight more evenly and gives it more strength. U-Panel bags have a 5 to 1 safety ratio and come in 2,000, 3,000 and 4,000-lb sizes for transporting dense, heavy materials.

With the Tubular bag the sides do not have seams since it’s a cylindrical tube. Tubular bags are less labor intensive to make, so they are more cost efficient to purchase. They are ideal for products generally transported and stored in containers built to carry up to 3,500 lb., and the tubular body design with no side seams is ideal for holding in some fine materials without using a liner.

3. Kind of product would be carried by U-panel and Tubular bulk bags ?
U-Panel bulk bags, a standard of the industry, are used to transport virtually any free-flowing (moving in a continuous stream like a fluid) granule, powder, pellet or flake product. However, due to their inherent additional strength, they are often specified for products or raw materials of a heavy nature that will exceed 3,500 lbs. per bag.
Tubular bags are generally better at carrying sifted or very fine products, such as carbon, flour and wheat.
