flexible medium bulk containers ( FIBC ), large bags , or large bags , are industrial containers made of fabric flexible designed to store and transport dry, flowable products, such as sand, fertilizer, and plastic granules.
FIBCs are most commonly made of thick woven polyethylene or polypropylene, either coated or uncoated, and are typically about 110 cm or 45-48 inches in diameter and vary in altitudes from 100 cm to 200 cm (39 to 79 inches). The capacity is usually about 1000 kg or 2,000 pounds, but larger units can save even more. A large bag designed to transport a metric ton of material will only weigh 5-7 lbs.
Transportation and loading is done on the palette or by lifting it from the loop. Bag made with one, two or four lifting loops. Single loop bag suitable for one person operation because there is no need for second person to put loop on hook loader. Discharging is done easily with special openings at the bottom like a drain spout, which there are several options, or by simply cutting it open.

History
Despite disagreements over which FIBC was first created and used, it is certain that they have been employed for various packaging purposes since the 1940s. These pioneers of FIBC as we know today are made of PVC rubber and are commonly used in the rubber industry for transporting carbon blacks for use as reinforcing agents in various rubber products.
In the 1960s, with the development of polypropylene combined with advances in weaving, the bulk bag as we know it now appears and is quickly adopted by various oil and chemical companies for storing and transporting powder and granular products.
During the oil crisis in the mid-1970s, FIBC actually came alone to transport large quantities of cement to the Middle East from across Europe for the rapid expansion of oil-producing countries. At its peak, more than 50,000 metric tons of cement are being sent each week to feed a vast development program.
Modern FIBC carries a number that grows over /sub> billion tons of products every year and is used to handle, store and move products as varied as cereals for chemicals and wheat flour for animal food. With a capacity of up to 3 m 3 and load capabilities ranging from 1 / 2 one ton to two tonnes of FIBCs is very effective cost, easy to recycle and ideal for almost all granules, powders, pellets or flakes that flow freely. FIBCs are also being developed to hold and filter fluid products. Maps Flexible intermediate bulk container

Electrostatic properties
- Type - A - no special electrostatic safety features
- Type - B - Type B bag is not capable of generating spread of brush dirt. This FIBC wall shows a breakdown voltage of 4 kilovolts or less.
- Type - C - Conductive FIBC. Built from electrically conductive fabric, designed to control electrostatic charge by grounding. The standard fabric used contains a conductive thread or ribbon.
- Type - D - FIBC anti-static, basically refers to bags that have static or static disipative properties without grounding requirements.

Use of flood barrier
Thailand used a large bag to erect a temporary wall to protect areas during the 2011 flood of Thailand. The walls were built using large bags, not the smaller traditional sandbags called large bag walls, or large bag obstructions.
In North America, bulk bags are often used in flood prevention as well. A 1850 kg bag (4070 lbs) has a footprint of at least 3 feet by 3 feet, and a height of nearly 4 feet - builds a sturdy sand wall, 400 regular sized sandbags at a time.
Clear FIBC
The disposal of FIBC for further processing of the products it contains must be carried out at stations designed specifically for this purpose to address the different difficulties associated with handling Large Bags weighing in some cases over 1000 kg. The stations must be equipped with a crane to lift the Big Bag, a safety cage to avoid the risk associated with falling, and a system containing dust emissions during discharge.
