A flexible intermediate bulk container (FIBC), jumbo, bulk bag, super sack, big bag, or tonne 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. [1] [2] [3]
FIBCs are most often made of thick woven strands of oriented polypropylene, [4] either coated or uncoated, and normally measure around 45–48 inches (114–122 cm) in diameter and varies in height from 100 to 200 cm (39 to 79 inches). Its capacity is normally around 1,000 kg or 2,200 lb, but the larger units can store even more. A FIBC designed to transport one metric ton (0.98 long tons; 1.1 short tons) 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.
Although there is disagreement on exactly where FIBCs were first made and 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 utilized 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, with the development of polypropylene combined with advances in weaving, the bulk bags as we 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 Middle East from across Europe for the rapid expansion of the oil producing countries. At its zenith, upwards of 50,000 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 each year and is used to handle, store and move products as varied as cereals to powdered chemicals and flour to animal feeds. With a capacity of up to 3 m3 (3.9 cu yd) and load capability ranging 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[ citation needed ] and ideal for virtually any free-flowing granule, powder, pellet or flake. FIBCs are also being developed to hold and filter fluid products.

Styles of Bag Construction: [5]
Circular – This style of bag is made on the loom as a tube and is the lowest standard of FIBC. It will not maintain its shape when loaded and will sit down and bulge out in the middle. It will resemble a tomato when loaded, as the product will stretch the fabric when it is subjected to the pressure of the product being loaded. Normally it would have cross corner lifting loops.
U-Panel – A U-panel bag is a step up from a circular bag, as it will have two pieces of fabric resembling a U shape that are sewn together to make the shape of the bag. It will maintain its square shape much better than the circular style.
Four-Panel – The four-panel bag is the best bag for staying square other than a baffle bag. It is made of up four pieces of fabric that make up the sides and one for the bottom. These are all sewn together which resists the stretching tendencies of the bag and holds it in a cube shape much better.
Baffle – This style will be the best at keeping the cube shape of your product when the bag is loaded. It has additional baffles sewn down each corner to act as a pocket to fill each corner. In addition, there are other pockets sewn on each side for all the product to gather around the baffles and pockets. These are perfect if you have a small diameter product such as soybeans which can flow through the baffles without getting hung up. These bulk bags will be easier to stack as they will make a nice square cube.

FIBC Bags with Liners
Thailand utilized big bags to erect temporary walls to protect areas during the 2011 Thailand floods. Walls built using big bags instead of smaller traditionally used sandbags were termed the big bag wall, or big bag barrier.
In North America, FIBCs are often used in flood prevention as well. An 1850 kg bag (4,070 lbs) has a foot print of at least 3 feet by 3 feet, and a height of almost 4 feet – building a solid wall of sand, 400 regular sized sandbags at a time. [7]
Emptying a FIBC in order to process its contents must be performed on a station specifically designed for this purpose in order to cope with the various difficulties associated the handling FIBCs, which can weigh over 1000 kg. Those stations must be equipped with a crane to lift the FIBC, a safety cage to avoid risks related to fall, and a system to contain dust emission during discharge. [8]
Intermodal freight transport involves the transportation of freight in an intermodal container or vehicle, using multiple modes of transportation, without any handling of the freight itself when changing modes. The method reduces cargo handling, and so improves security, reduces damage and loss, and allows freight to be transported faster. Reduced costs over road trucking is the key benefit for inter-continental use. This may be offset by reduced timings for road transport over shorter distances.
A sandbag or dirtbag is a bag or sack made of hessian (burlap), polypropylene or other sturdy materials that is filled with sand or soil and used for such purposes as flood control, military fortification in trenches and bunkers, shielding glass windows in war zones, ballast, counterweight, and in other applications requiring mobile fortification, such as adding improvised additional protection to armored vehicles or tanks.
Earthbag construction is an inexpensive building method using mostly local soil to create structures which are both strong and can be quickly built.
A coffee bag is a container for shipping and storing coffee. Coffee beans are usually transported in large jute sacks, while coffee sold to consumers may be packaged as beans or ground coffee in a small, sealed plastic bag.
The lighter aboard ship (LASH) system refers to the practice of loading barges (lighters) aboard a bigger vessel for transport. It was developed in response to a need to transport lighters, a type of unpowered barge, between inland waterways separated by open seas. Lighters are typically towed or pushed around harbors, canals or rivers and cannot be relocated under their own power. The carrier ships are known variously as LASH carriers, barge carriers, kangaroo ships or lighter transport ships.
Intermediate bulk containers are industrial-grade containers engineered for the mass handling, transport, and storage of liquids, semi-solids, pastes, or solids. The two main categories of IBC tanks are flexible IBCs and rigid IBCs. Many IBCs are reused or repurposed.
A silo is a structure for storing bulk materials.
Nonwoven fabric or non-woven fabric is a fabric-like material made from staple fibre (short) and long fibres, bonded together by chemical, mechanical, heat or solvent treatment. The term is used in the textile manufacturing industry to denote fabrics, such as felt, which are neither woven nor knitted. Some non-woven materials lack sufficient strength unless densified or reinforced by a backing. In recent years, non-wovens have become an alternative to polyurethane foam.
A bulk box, also known as a bulk bin, skid box, pallet box, bin box, gaylord, or octabin, is a pallet-size box used for storage and shipping of bulk or packaged goods. Bulk boxes can be designed to hold many different types of items such as plastic pellets, watermelons, electronic components, and even liquids; some bulk boxes are stackable.
A tank container or tanktainer is an intermodal container for the transport of liquids, gases and powders as bulk cargo. It is built to the ISO standards, making it suitable for different modes of transportation; as such, it is also called an ISO tank. Both hazardous and non-hazardous products can be transported in tank containers.
In shipping, break-bulk, breakbulk, or break bulk cargo, also called general cargo, is goods that are stowed on board ships in individually counted units. Traditionally, the large numbers of items are recorded on distinct bills of lading that list them by different commodities. This is in contrast to cargo stowed in modern intermodal containers as well as bulk cargo, which goes directly, unpackaged and in large quantities, into a ship's hold(s), measured by volume or weight.
A thermal bag is a type of thermally insulated shipping container in the form of a bag which can be carried, usually made of thermally insulating materials and sometimes a refrigerant gel. It is used to help maintain the temperature of its contents, keeping cold items cold, and hot items hot.
A shipping container is a container with strength suitable to withstand shipment, storage, and handling. Shipping containers range from large reusable steel boxes used for intermodal shipments to the ubiquitous corrugated boxes. In the context of international shipping trade, "container" or "shipping container" is virtually synonymous with "intermodal freight container", a container designed to be moved from one mode of transport to another without unloading and reloading.
Flexible tanks are a kind of storage equipment for liquids such as water or oil. Compared to steel tanks, flexible tanks have many advantages, including lighter weight and being rustproof, foldable, and quicker and easier to set up. With the same capacity, an empty flexible tank may have just 10% of a steel tank's weight. The disadvantages of flexible tanks include lower durability and shorter longevity. Some flexible tanks can be used as transport containers on trucks, ships, or aeroplanes, with some suitable for use in airdrops, helicopter swing, or hauling water.
A bag is a common tool in the form of a non-rigid container, typically made of cloth, leather, bamboo, paper, or plastic. The use of bags predates recorded history, with the earliest bags being lengths of animal skin, cotton, or woven plant fibers, folded up at the edges and secured in that shape with strings of the same material. Bags can be used to carry items such as personal belongings, groceries, and other objects. They comes in various shapes and sizes, often equipped with handles or straps for easier carrying.
A container is any receptacle or enclosure for holding a product used in storage, packaging, and transportation, including shipping. Things kept inside of a container are protected on several sides by being inside of its structure. The term is most frequently applied to devices made from materials that are durable and are often partly or completely rigid.
Plastic containers are containers made exclusively or partially of plastic. Plastic containers are ubiquitous either as single-use or reuseable/durable plastic cups, plastic bottles, plastic bags, foam food containers, Tupperware, plastic tubes, clamshells, cosmetic containers, up to intermediate bulk containers and various types of containers made of corrugated plastic. The entire packaging industry heavily depends on plastic containers or containers with some plastic content, besides paperboard and other materials. Food storage nowadays relies mainly on plastic food storage containers.
Package handles, or carriers, are used to help people use packaging. They are designed to simplify and to improve the ergonomics of lifting and carrying packages. Handles on consumer packages add convenience and help facilitate use and pouring. The effect of handles on package material costs and the packaging line efficiencies are also critical. A handle can be defined as “an accessory attached to a container or part for the purpose of holding or carrying.” Sometimes a handle can be used to hang a package for dispensing or use.
Caged IBC totes are one of, if not the most commonly used, of all current intermediate bulk container design types. Caged IBC totes are handling and shipping containers for the storing, transit, and operation integration of various commodities, with the most common being water. Caged IBCs are often utilized as one-use containers, especially when it comes to hazardous materials, but are also suitable for reuse under many conditions. This IBC type often features an interior liner, blow-mold manufactured from polyethylene, that is structurally supported by a protective cage frame, often of galvanized steel composition. Caged IBCs are engineered for the bulk handling of liquids, semi-solids, as well as solid materials. All materials can present certain safety and compatibility concerns, especially hazardous liquids, and proper guidance is always recommended whenever using caged IBC totes for harsh chemicals.
Bags or sacks for flour range in size and material, from large bulk bags, in cotton or woven polypropylene, to smaller consumer packaging, often made of paper.
