flexible intermediate bulk container (FIBC), jumbobulk bagsuper 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.

FIBCs are most often made of thick woven polyethylene or polypropylene, either coated or uncoated. 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.

Styles of Bag Construction: Circular, U-Panel, Four-Panel, Baffle.

Specialty Bags:

♦ Pharmaceutical - similar to food grade certifications;

♦ UN certified - will have to undergo many test 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 Bag - used for potatoes and other fruits/vegetables for allowing the product to breath.

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 which are dusting or hazardous will have to have a polypropylene liner inside the FIBC to eliminate sifting of the woven FIBC g.

♦  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.

Used to transport:

Chemicals, Pharmaceutical Drugs, Fertilizers, Fiberglass, Food Products, Grains, Shotcrete, Construction materials (sand, gravel), Pigments, Plastics, Refractories, Seeds, Salt, Peanuts, Starch, Hazardous Waste Material - UN Rated, Flyash, Minerals, Cattle Feed, Wool, Scrap…

These above are some typical types of big bag types in the market. Most of these types can be combined with each other. It is possible to produce a big bag which is at the same time formstable, conductive, foodclean, an UN bag and equipped with an inliner.
