FIBCs (Flexible Intermediate Bulk Containers) are also known as bulk bags, jumbo bags, tote bags, and super sacks. They are made from a strong, flexible fabric called polypropylene (PP). Polypropylene is a thermoplastic polymer that can be used in many different types of applications. Polypropylene is very durable, and it withstands daily wear and tear. The elasticity and toughness of the fabric defines the materials ability to deform without breaking. The fabric panels that are manufactured of the woven polypropylene are then sewn, sealed, and put together to produce bulk bags. Woven polypropylene is made from polypropylene resin, which is made from petroleum feedstock. Woven polypropylene bulk bags can be used for a wide variety of storage and shipping purposes.
