FIBCs are also known as bulk bags, big bags, Jumbo bags and super sacks. Essentially, an FIBC bag is an industrial container in which you can store materials like legal cannabis, hemp, agricultural and pharmaceutical products. An FIBC bag is made from flexible fabric designed to transport and store dry, flow able products like fertilizer, sand or granules of plastic. Typically, an FIBC bag is made of thick woven strands of polypropylene and can be coated or uncoated.
