It is good for the loss cargo safty its avoid the moisture and dust. A flexible intermediate bulk container (FIBC), bulk bag, 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. Its capacity is normally around 1,000 kg or 2,200 lb, but the larger units can store even more. A bulk bag designed to transport 28 ton weigh 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.
