At first glance, Type B FIBC bags might look indistinguishable from Type A big bags. They boast a similar construction, although the material uses a lower breakdown voltage, making these bags slightly more conductive. In certain situations, Type B bags can be used as intermediate bulk containers for transporting some combustible materials, such as dry powders.

While the coating of Type B bags affords them some protection, you need to be careful when using them in certain environments. These bags can prevent propagating brush discharges from happening, but they’re not completely anti-static. Take care to ensure the outside of the bag doesn’t become contaminated with anything flammable or conductive solutions, as an outside spark can ignite these.
