FIBC (Flexible Intermediate Bulk Container) bags are made from a thick, woven polyurethane with a UV enhanced finish. They can hold a little over 2,000 pounds and fit 1 cubic yard of volume, but keep in mind that they're not waterproof. The handles on the corners are used for lifting heavy loads with a forklift. These flexible bulk bags are designed for storing and transporting goods such as sand, fertilizer, granules of plastic, and other industrial products. Check out the video for more info!
