Flexible intermediate bulk container

A flexible intermediate bulk container (FIBC), jumbo bag, bulk bag, super sack or a 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.

[1][2][3] FIBCs are most often made of thick woven strands of oriented polypropylene,[4] either coated or uncoated, and normally measure around 45–48 inches (114–122 cm) in diameter and varies in height from 100 to 200 cm (39 to 79 inches).

Although there is disagreement on exactly where FIBCs were first made and used, it is certain that they have been employed for a variety of packaging purposes since the 1940s.

By the 1960s, with the development of polypropylene combined with advances in weaving, the bulk bags as we know them today came into being and were rapidly adopted by a wide variety of oil and chemical companies to store and transport powdered and granular products.

With a capacity of up to 3 m3 (3.9 cu yd) and load capability ranging from 0.5 to 2 metric tons (0.49 to 1.97 long tons; 0.55 to 2.20 short tons) FIBCs are highly cost effective, easily recyclable[citation needed] and ideal for virtually any free-flowing granule, powder, pellet or flake.
