Introduction Of FIBC Bags

Posted by Blue Vision Exim on February 20th, 2020

A flexible intermediate bulk container (FIBC), bulk bag, super sack, or big bag, is an industrial container made from flexible fabric that's designed for storing and transporting dry, flowable products, like sand, fertilizer, and granules of plastic.

FIBCs are most frequently made from thick woven polypropylene or polypropylene, either coated or uncoated, and normally measure around 45–48 inches (114–122 cm) in diameter and varies tall from 100 to 200 cm (39 to 79 inches). Its capacity is generally around 1,000 kg or 2,200 lb, but the larger units can store even more. A bulk bag designed to move one MT (0.98 long tons; 1.1 short tons) of fabric will itself only weigh 5–7 lb (2.3–3.2 kg).

Transporting and loading is completed 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's no need for a second man to place the loops on the loader hook. Emptying is formed easy by a special opening within the bottom like a discharge spout, of which there are several options, or by simply cutting it open.

History

Although there's disagreement on exactly where FIBCs were first made and used, it's certain that they need been employed for a spread of packaging purposes since the 1940s. These forerunners of the FIBC as we all know it today were manufactured from PVC rubber and usually utilized within the rubber industry for the transportation of lampblack to be used as a reinforcing agent during a sort of rubber products.

By the 1960s, with the event of polypropylene combined with advances in weaving, the majority bags as we all 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.

It was during the oil crisis of the mid-1970s that the FIBC really came into its own for transporting huge quantities of cement to the center East from across Europe for the rapid expansion of the oil producing countries. At its zenith, upwards of fifty ,000 metric tons (49,000 long tons; 55,000 short tons) of cement was being shipped out on a weekly basis to feed the vast building program.

The modern FIBC transports a growing figure of over 250,000,000 metric tons (246,000,000 long tons; 276,000,000 short tons) of product annually and is employed to handle, store and move products as varied as cereals to powdered chemicals and flour to animal feeds. With a capacity of up to three m3 (3.9 cu yd) and cargo capability starting 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 and ideal for virtually any free-flowing granule, powder, pellet or flake. FIBCs also are being developed to carry and filter fluid products.

Flood barrier use: FIBC

Thailand utilized big bags to erect temporary walls to guard areas during the 2011 Thailand floods. Walls built using big bags rather than smaller traditionally used sandbags were termed the large bag wall, or big bag barrier.

In North America, bulk bags are often utilized in flood prevention also . An 1850 kg bag (4,070 lbs) features a foot print of a minimum of 3 feet by 3 feet, and a height of just about 4 feet – building a solid wall of sand, 400 regular sized sandbags at a time.

Emptying FIBC

The discharge of FIBC for further processing the merchandise it contains must be performed on a station specifically designed for this purpose so as to deal with different difficulties linked to the handling of massive Bags weighing in some cases quite 1000 kg. Those stations must be equipped with a crane to lift the large Bag, a security cage to avoid risks associated with fall, and a system to contain dust emission during discharge.
