A flexible intermediate bulk container (FIBC), jumbo, bulk bag, super sack, or big bag, is an industrial container made of flexible fabric that is designed for storing and transporting dry, flowable products, such as sand, fertilizer, and granules of plastic.
Depending on the type of machinery operated and the product to be stored inside the FIBC bag, a variety of filling options are available. Tops may not be necessary for products of low value and not subject to moisture damage. On the other hand, the duffel top still provides easy access but ensures integrity of the contents. The top, with a draw cord permits air flow but still confines the product, and a cone top allows for extra filling for those materials which settle in time. Filling systems, (including spouts) can be attached to different accessories for full customization.
Choosing the proper discharge option saves the end-user both time and money and improves FIBC product handling efficiency. Many customers choose not to reuse their bags, for these customers a flat bottom which is slit to release the material is probably the most economical option. For those who prefer some reusability, a variety of discharge options are available. Many spout options can be produced to match equipment and hygiene requirements. The covers over the tied-off spout protect products from contamination. A full-bottom discharge is also available.
