FAQ:

1. What is the difference between Circular and U-panel big bags?

Circular bags are made from tubular shape fabric that weaved on a circular loom. Then the fabric is cut into the correct height according to bag size. U-panel bags are made from one flat U-panel fabric and 2 sides panel sewing together.

2. Are these bags water-tight or water proof?

No, as the fabric is made from pp woven material, which is not water proof. Users usually take a coating or lamination as a moisture barrier, by moisture barrier we mean a light amount of water. Lamination can take some help for water proof, however the use of an internal liner works much better. And technically it is still not 100% water proof. And pp bulk bag with liquid liner is the best choice to pack liquid material.
