FIBC (flexible intermediate bulk container ), jumbo, bulk bag, super sack, or 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.
FIBC are most often made of thick woven strands of oriented polypropylene, either coated, 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). Its capacity is normally around 1,000 kg or 2,200 lb, but the larger units can store even more. A FIBC designed to transport one metric ton (0.98 long tons; 1.1 short tons) of material will itself only weigh 5–7 lb (2.3–3.2 kg).
Transporting and loading is done on either pallets or by lifting it from the loops. Bags are made with either one, two or four lifting loops. The single loop bag is suitable for one man operation as there is no need for a second man to put the loops on the loader hook. Emptying is made easy by a special opening in the bottom such as a discharge spout, of which there are several options, or by simply cutting it open.
This type of packing, jumbo bag, is eco-friendly. It has two layers that the inner layer is 100% consumable and the outer one is recyclable. In comparison to new steel drums, its wastage is approximately zero and it doesn't leak.
Types of Flexible Intermediate Bulk Container
Pharmaceutical - similar to food grade certifications
UN certified - will have to undergo many tests to ensure it can withstand the stress and still eliminate spillage of hazardous material
Food Grade - has to be manufactured in a clean room environment which is BRC or FDA approved
Ventilated FIBC - used for potatoes and other fruits/vegetables for allowing the product to breathe
Different lift loop configurations:
One Loop
Two Lift Loops
4 Lift Loops
Types of lift loops
Standard lift loops
Cross corner lift loops
FIBC Bags with Liners
Products that are dusting or hazardous will have to have a polypropylene liner inside the FIBC to eliminate sifting of the woven FIBC.
Liners can be made from Polypropylene, Polyethylene, Nylon, or a metal (Foil) liner
Electrostatic properties
Type – A – no special electrostatic safety features
Type – B – Type B bags are not capable of generating propagating brush discharges. The wall of this FIBC exhibits a breakdown voltage of 4 kilovolts or less.
Type – C – Conductive FIBC. Constructed from electrically conductive fabric, designed to control electrostatic charges by grounding. A standard fabric used contains conductive threads or tape.
Type – D – Anti-static FIBCs, essentially refers to those bags which have anti-static or static dissipative properties without the requirement of grounding.
