The History of SUPER SACK® FIBCs​

For more than 130 years, United Bags has been building better ways to package, protect, and move products. The SUPER SACK® FIBC is one of the most important innovations in that story — a simple, robust idea that redefined bulk handling across industries. Today, United Bags proudly stewards the history of SUPER SACK® FIBCs, its trademark, and advances its legacy of safety and performance.​

What are SUPER SACK® FIBC Bags?​

SUPER SACK® is the gold standard for flexible intermediate bulk containers (FIBCs). These large, lightweight bags are woven from polypropylene and designed specifically to store and transport dry, flowable materials with durability and efficiency.

As the originator and exclusive provider of the SUPER SACK® brand through our legacy BAG Corp operations, United Bags continues to set the technical expectations for FIBC performance.​
