Super sack, bulk bag, jumbo bag, tote bag, and FIBC often refer to the same class of woven polypropylene industrial container, but the details determine whether a bag is reusable, recyclable, or saleable.
Common names
FIBC means flexible intermediate bulk container. In North America, buyers often say super sack or bulk bag. International suppliers may say jumbo bag or big bag.

Performance terms
Safe working load is the rated weight a bag is designed to carry. Safety factor is a test ratio related to the intended use class. These ratings should be verified from labels or documentation.
Coated fabric can help reduce sift. Liners add barrier protection. Baffles help the filled bag remain square for more stable stacking and space use.
Handling terms
Corner loops, cross-corner loops, stevedore straps, lift tunnels, duffle tops, fill spouts, discharge spouts, and flat bottoms all affect how the bag can be filled, moved, emptied, and resold.
Frequently asked questions
Is an FIBC the same thing as a super sack?
In everyday industrial buying, yes. FIBC is the technical category, while super sack is a common market term.
What is a baffle bulk bag?
A baffle bag has internal panels that help the filled bag hold a squarer shape, which can improve stacking, storage density, and container loading.
