Circular FIBCs are made from polypropylene that is woven into a circle. The circular material is then cut to the desired length and the bottom, top (if specified) and straps are sewn to the seamless body of the bag. Having minimized the number of seams, circular FIBC’s are typically the best choice for containing very fine powdery or granular product. They also hold an advantage in the ease of use department as the straps will stand up on their own.
