Flexible Intermediate Bulk Containers (FIBC) are widely used for storage, transportation and handling of powder, flake or granular materials.
Typically they are constructed from woven polypropylene (PP) fabric in the form of cubic bags. The fabric used may be a single layer, with extra loose liner, or laminated. The UV treated PP is a good electrical insulator. Due to this, during filling and discharge time there is a steady accumulation of charge, within the product which is transferred to the walls of the bag.
