Circular bags (FIBC) are an excellent alternative to 4-Panel bags. They have a circular/tubular body that is seamless with only a top and bottom panel sewn into the bag, and have a reinforcement panel on the body. This style comes with cross corner loop attachments that are attached on the reinforcement panel of the fabric. Circular style bags are made from a fabric that is woven in a circular loom, into a continuous tube that is then cut to the appropriate sized height. They are ideal for fine and hydroscopic materials.
