This depends on many factors including whether the IBC will be reused or not, the durability needed and legal requirements.
In the case of cube shaped rigid IBCs, the inner containers are often made from a plastic such as polyethylene or high density polyethylene (HDPE). They are also available in other materials such as aluminum or galvanized iron. TranPak’s IBCs are made of HDPE
. The rigid outer container or cage is usually made from galvanized tubular steel or iron.
Folding IBCs don’t have a rigid outer cage and are made of very durable plastic that folds inward when empty.
Flexible IBCs or bulk bags are made from various heavy duty materials such as woven polypropylene or polyethylene.
