FIBC Bulk Bags

What Is an FIBC?

The term, “FIBC,” is shorthand for “flexible intermediate bulk container.”  FIBC is used to refer to different types of bulk tote bags and the other styles of bulk bags that companies use to store and transport free-flowing dry products and other materials. FIBC bulk bags are normally made using woven polypropylene, and they can usually hold between 2,000 – 4,000 pounds of product per bag. In addition to being known as bulk bags, flexible intermediate bulk containers are often commonly referred to as “big bags” and “bulk sacks.”

Top and Bottom Types for Bulk Bags

In addition to being differentiated from one another based on their ability to guard against the buildup of static electricity and their construction, bulk bags can be distinguished based on other factors. These factors include the type of top and bottom a bag has.

Common tops found on bulk sacks include the following:

  • Duffle Tops: A duffle top can be added to any kind of bulk bag, including circular and U-panel bulk sacks.  A duffle top provides a bag with a fill opening that has the same width and depth dimensions as the bag it is on. This kind of versatile top works well with many kinds of filling machines and is useful in many filling procedures. Once a bulk bag is filled, the duffle top is closed to protect the product in the bulk sack.
  • Spout Tops: Spout tops help to reduce the amount of dust that is generated when a bag is being filled. A bag with a spout has a chute on its top that product runs through to fill the bulk bag. While spouts can be customized to suit your specific needs, the bulk bag industry does have standards for the most frequent applications, with the most common measure being 14-inches in diameter and 18-inches in length.
  • Open Tops: Open top big bags are exactly what they sound like: open. They don’t have a top panel to cover the contents and are, therefore, generally easy to fill with products that don’t need to be protected from external elements.

Depending on a variety of factors, the FIBC you need may have one of the following bottoms:

  • Spout Bottom: Spout bottom bulk sacks have a spout on their bottom that is used to empty whatever product the bag is holding. The most common dimensions for a spout on the bottom of a bulk bag are the same as the ones used for a spout on the top of a bulk sack.
  • Plain Bottom: If a bulk bag has a duffle top and a plain bottom, it’s normally emptied through its duffle top or cut open to remove its contents from the bottom. Bags with this type of bottom are typically used just one time.
  • Full Bottom: A full bottom discharge bulk bag has a spout that’s used for emptying the bag, and it has the same characteristics of the bag itself. This sort of bottom is appropriate when a bulk bag is being used to store or transport materials that clump together into masses.
