What Are FIBCs?
FIBCs, short for Flexible Intermediate Bulk Containers, are bulk packaging bags made from polypropylene fibers.
They are sturdy, flexible, and can hold up to 5,000 pounds of materials. These bags are best with flowable, solid substances or powders, making them invaluable to industries such as chemicals, mining, resin, or plastic. When flat, they weigh much less than boxes or drums, enabling you to transport more material safely.

Circular
For finer materials; no side seam provides high vertical pressure
Baffle
Used for materials that pose electrostatic risk; no grounding necessary
