The development of FIBC
A Flexible Intermediate Bulk Container, FIBC , big bag, bulk bags, pp woven bags, or super sack is a standardized container in large dimensions for storing and transporting and storing for example sand, fertilizers , granules of plastics or other dry products. It is most often made of thick woven polyethylene or polypropylene and normally measures around 110 × 110 cm and varies in height from 100 cm up to 200 cm. Its capacity is normally around 1000 kg but the larger units can store even more. Transporting and loading is done on either pallets or by lifting it in loops.
History
Although there is disagreement on exactly where FIBCs were first used it is certain that they have been employed for a variety of packaging purposes since the 1940s. These forerunners of the FIBC as we know it today were manufactured from PVC rubber and generally utilised within the rubber industry for the transportation of Carbon Black to be used as a reinforcing agent in a variety of rubber products.
By the 1960s development of polypropylene, combined with advances in weaving, the bigbags as we know it today came into being and was rapidly adopted by a wide variety of oil and chemical companies to store and transport powdered and granular products.
It was during the oil crisis of the 1970s that the china FIBC really came into its own for transporting huge quantities of cement to the Middle East from across Europe for the rapid expansion of the oil producing countries. At its zenith, upwards of 50,000 metric tons of cement was being shipped out
Classification of FIBCs
Construction
1. U-Panel construction
2. Circular construction
3. Baffle construction
4. Four side panel construction
Electrostatic properties
? Type - A - no special electrostatic safety features
? Type - B - Made from plain (non-antistatic) polypropylene.Type B bags are not capable of generating propagating brush discharges.The wall of FIBC exhibits a breakdown voltage of 4 kilovolts or less.
? Type - C - Conductive FIBC. Constructed from electrically conductive fabric.A standard fabric is used which contains conductive threads.
? Type - D - Anti Static. FIBC's essentially refers to those bags which have antistatic or static dissipative properties without the requirement of earthing.
