Circular (Tubular)
Circular (Tubular) bags are constructed with two main body components (body tube + base). The body tube is made with seamless tubular fabric that forms all sides of the bag allowing for stitching only for the top and base of the bag. Although the fabric is tubular, when filled the circular baffle bag will still resemble a square bag. There is a common misconception with circular bags regarding their shape when filled. They are not truly circular; they are simply constructed with a single piece of fabric that forms all four sides of the bag. While they still resemble square/rectangular FIBCs, they will hold that shape the least of the construction types when filled.

This bag is the ideal option for fine materials due to the limited amount of seams.

Whether transporting bulk or pellets, the flexible Medium Bulk Container (FIBC) is a very viable storage solution. These industrial containers are known by their many names, such as bulk bags, large bags or super sacks, which are made of flexible woven materials that can store paper, sand, fertilizers and petroleum products, among others. Not only are they capable of accommodating many types of items, but they also make transporting them safe and cost-effective.
