Why Type B Breathable FIBC Is Not Optional for Fine Powder Handling
Apr 28, 2026
Every year, facilities handling combustible dust lose millions to fire and explosion incidents. The statistics are sobering: between 2020 and 2024, the U.S. Chemical Safety Board tracked over 120 reported dust-related incidents across industrial sectors, with the agriculture, chemical, and mineral processing industries accounting for nearly 70% of total losses (CSB data, 2024).
When it comes to bulk bag specifications, the "breathable" feature in a Type B FIBC is often treated as a nice-to-have. In practice, it's one of the most overlooked engineering controls in pneumatic filling operations.
The Physics You Can't Ignore
During high-rate filling, air trapped inside the bag must escape. In standard woven polypropylene bags with tight weave construction, the air pushes back. The result? Dist...
