A pneumatic bladder is an inflatable bag technology with many applications. Pneumatic bladders are used to seal ducts to contain chemical spills or gases. Pneumatic bladders are used for the containment of chemical spills, oil spills or fire water on water to prevent them from entering the environment in the form of booms; the Reef Ball Foundation uses a pneumatic bladder technology to float an artificial coral reef into location deflate the bladder to sink the reef to the bottom. Pneumatic bladders, known as dunnage bags, are used to stabilize cargo within a container. Pneumatic bladders are used in medical research. Leading edge inflatable kites use pneumatic bladders restrained by a fabric case. Many of the wing's airfoil ribs are bladdered.

Fuel bladders or fuel storage bladders are collapsible, flexible storage bladders that provide temporary or long term storage for industrial liquids. These pillow shaped tanks are designed for large volume liquid transport, industrial chemicals, potable water and fuel storage. Standard fuel bladder tanks sizes range from 100 US gallons to 200,000 US gallons capacities and larger and custom fuel storage bladders and cells are available, although at sizes exceeding 50,000 US gallons there is an increased spill risk. To minimize the risk of leakage, for the sake of containing a catastrophic spill, all fuel bladders should be housed in secondary containment; the use of fuel bladders without precautionary measures should not be undertaken. The fines involved with fuel spills are well known and the EPA has set clear guidelines for the use of secondary containment concerning fuel bladders. Fuel bladders are used in various fields, such as agribusiness, public works, humanitarian and industrial areas.
Standard tanks are designed for land based use and operations, but can be used in marine settings and in aviation given proper support. Fuel bladders are commonly used in oil spill recovery operations. High end fuel bladders offer a high degree of protection of the stored liquids, ensuring the contents never come in contact with air; this ensures that there is no risk of explosion due to gas formation. In order to prevent liquid contamination, a neutral barrier film is added to the fuel bladder's inner side. Fuel bladders are most useful in situations where critical infrastructure has been compromised or does not exist. Benefits of using a flexible storage system like fuel bladders is their ability to be transported and set up quickly. GMA Cover Corp. advertises that their pillow shaped bladders are foldable at less than 5% of the total volume. Other unique characteristics of fuel bladders are their high resistance to climatic conditions, which makes them useful for use in disaster zones and wartime desert operations.
High end fuel bladders are made of elastomer coated fabrics manufactured by homogeneous vulcanization in one operation. The fabrics ensure the mechanical resistance. Coating and design engineering grant chemical properties and water tightness. Fuel bladders can come equipped with all the necessary components for transportation, for example water transportation or fuel transportation on vehicles. Flexible tanks are equipped with adjustable skirts and adjustable towage straps designed to provide high resistance to transport constraints. Adjustable skirts may be replaced by a strap net in case the users need to transform a traditional storage tank to a transportable flexible tank. Specially developed Flexible fuel bladders can be towed by sled, as in the unique Antarctic expeditions made by American and British science teams. Flexible pillow tanks are used as'water bladders'; the synthetic fabrics used are strong to avoid damage and to prevent leakage. Ultra-tough “crash-worthy” fuel bladders, reinforced with such fibers as Kevlar, are popular in the motorsports industry and are considered a critical safety component, mandated by racing’s top series such as Formula 1 and NASCAR.
The development of the flexible “crash-worthy” fuel bladder has reduced the number of fires, subsequent explosions experienced in a violent auto racing crashes. The same “crash-worthy” technology can be found in military/industrial vehicles, combatant craft and air-craft. Ferry tank Self-sealing fuel tank
A bag-in-box or BiB is a type of container for the storage and transportation of liquids. It consists of a strong bladder made of several layers of metallised film or other plastics, seated inside a corrugated fiberboard box; the bag is supplied to the company. The company filling the bag with its product removes the tap, fills the bag and replaces the tap and the bag is placed in the box; the bags are available as singles for semi-automatic machines or as web bags, where the bags have perforations between each one. These are used on automated filling systems where the bag is separated on line either before the bag is automatically filled or after. Depending on the end use there are a number of options that can be used on the bag instead of the tap; the bags can be filled from chilled product temperatures up to 85 degrees Celsius. Bag-in-box packaging can be made using form seal fill technology, where the bags are manufactured on-line from reels of film the FlexTap is inserted filled on an integral rotary head filler.
Bag-in-box is used for the packaging of wine, soda fountain syrup products, liquid chemicals, water. The first commercial bag-in-box system was invented by William R. Scholle in 1955 for the safe transportation and dispensing of battery acid. In 1991, William Scholle was inducted into the packaging hall of fame for his invention; the BiB has many common commercial applications. One of the most common uses of BiBs by commercial users are to supply syrup to soft drink fountains and to dispense bulk supplied condiments such as ketchup or mustard in the foodservice industry in fast food outlets. BiB technology is still used for its original application of dispensing sulfuric acid for filling lead-acid batteries in garages and dealerships; as explained further below, BiBs have been implemented for consumer applications like boxed wine. For commercial syrup applications, the customer opens one end of the box and connects a compatible connector to a fitment on the bag to pump out its contents; the fitment itself contains a one-way valve which opens only with pressure from the attached connector and which prevents contamination of the syrup in the bag.
For consumer applications like boxed wine, there is a tap present on the bag, so all the consumer has to do is locate the tap on the outside of the box. Bag in a box packaging is liked by producers. Seen from the environmental perspective, a bag has benefits; the bag allows a contents of 1.5 -- 1000 liters. The material it is made from is lighter than the other plastic alternatives providing it with a better carbon footprint. The'wine cask' was invented by Thomas Angove of Angove's, a winemaker from Renmark, South Australia, patented by the company on April 20, 1965. Polyethelene bladders of 1 gallon were put into corrugated boxes for sale to consumers. An original design required that the consumer cut the corner off the bladder inside the box, pour out the desired quantity of wine and reseal it with a special peg. In 1967, Charles Malpas and Penfolds Wines patented a plastic, air-tight tap welded into a aluminised film bladder, making storage much more convenient for consumers. All modern wine casks now utilise some sort of plastic tap, exposed by tearing away a perforated panel on the box.
The main advantage to bag-in-a-box packaging is that it prevents oxidation of the wine during dispensing. Rather than working like a conventional tap, the bladder uses gravity pressure to squeeze liquid out of the bladder, whereas a conventional barrel tap works by allowing incoming air to displace the contents. After opening, wine in a bottle it is oxidised by air in the bottle which has displaced the wine poured. Cask wine is not spoilage due to slow consumption after opening. Although a promising technology, there have been design problems; the impermeable bladders tend where the two halves are joined. If tap components are deposited in the bladder during assembly, all the bladders must be destroyed to find the components as the bladders are opaque, it has been difficult to manufacture taps that don't leak air into the bladder since tap parts don't join neatly, although there have been significant improvements. Most red wines require breathing before consumption, not possible with casks, so wine has air circulated through prior to bottling, which reduces shelf life considerably.
Most casks will have a best-before date stamped. As a result, it should be consumed within the prescribed period. Bag-in-box is used extensively in the packaging of processed fruit and dairy products in aseptic processes. Using aseptic packaging equipment, products can be packed in aseptic packaging. Pasteurised or UHT treated products packed into this format can be "shelf stable", requiring no refrigeration; some products can have a shelf life of up to 2 years, depending on the type of bag, used. The key to this unique system is that the product being filled is not exposed to the external environment at any stage during the process and as such, there is no possibility of a bacterial load being added to the product during the filling process. To ensure there is no contamination from the packaging, the bag is irradiated after the bag manufacturing process; these packs are from 10 to 1200 litres and offer the advantage of cheap, disposable and
A hydration system is an apparatus used in recreation and other sustained outdoor activities. It is intended to help its user carry liquid to support the physical effort involved in the activity; such systems for consumers were first sold to cyclists, by the 1990s had found a substantial market among hikers. Familiar commercial models can be recognized worn by western military personnel in southwest Asia. In practice, such a system is always a commercially manufactured unit that features at least a flexible bladder of one or a few liters' capacity with some means a screwtop, to fill and reliably seal it, a light hose to convey the beverage to the user's mouth, a bite valve that starts and stops the flow through the hose with minimal effort. Common are designs that include specific hands-free means to comfortably carry the hydration system. Hydration systems first appeared commercially in the late 1980s or early 1990s, at backpacking stores, they were adopted by US special operations troops in the early 1990s, became standard issue for all US troops in the 1990s.
The concept of the hydration system appeared in Robert A. Heinlein's 1955 novel, Tunnel in the Sky, where the main character has "a belt canteen of flexible synthetic divided into half-litre pockets; the weight was taken by shoulder straps and a tube ran up the left suspender, ending in a nipple near his mouth, so that he might drink without taking it off." The overall geometry of the bladder is nearly universal: The largest dimension is the vertical one, taking advantage of the long vertical dimension of the human torso. The hose joins the bladder near the bottom of the bladder, to maximize the amount of accessible liquid; the bladder's change in volume as it is emptied is reflected in the decrease of its smallest dimension. Typical commercial hydration systems are available with three fundamental approaches: A "bare bladder", intended to be carried in a matching pocket of a "hydration-system compatible" backpack; as part of an integrated design incorporating both a backpack and the hydration system with at least a few pockets-worth of storage space for other items.
A basic hydration system in a protective fabric shell, so that the bladder is unlikely to be damaged by other gear that it shares the interior of an ordinary pack with. Some manufacturers offer parts for replacement or customization, whether compatible only with their own hydration systems, or usable with others'. While a hydration system is being carried in a vehicle, there is some danger of the bite valve being squeezed, opening it to leakage or a steady flow; the bite valve may be installed with a right-angle extension between it and the hose, to achieve a preferred positioning and angle of the valve relative to the user's mouth. Position and angle may be adjusted by clips that clip to a pack strap and control the hose's path Plastic foam surrounding the hose can be used to reduce heat transfer between the environment and liquid in the hose: keeping a cold liquid cool longer in summer and slows a liquid freezing in winter. At least one manufacturer offers a tethered, slip-off, foam cowl that slows freezing of the liquid in the bite valve, reduces contamination of the bite valve.
At least one manufacturer, MSR, offers a in-line ceramic based filter, allowing use of local water supplies for refill. Ceramic filters can be cleaned at home by back flushing with clean water so no replacements are needed. Sets of cylindrical brushes permit mechanical removal of biofilm that will grow on the surface inside the system. Means of holding the bladder walls apart to encourage drying between uses are available, such as a plastic frame that collapses to pass through the fill opening, but expands inside the bladder to hold the sides apart near the corners. Various specialized practices may be applied in using a hydration system. Depending on the size of the opening for filling the bladder, it may be convenient to include, in hot weather, ice cubes or crushed ice when filling it. In theory too much ice means running out of liquid water while the bladder still has ice occupying space that could have been filled by more water (so it helps to take account of how temperature and humidity affect the balance between consumption ra
Pig bladder is the urinary bladder of a domestic pig, similar to the human urinary bladder. Today, this hollow organ has various applications in medicine, in traditional cuisines and customs; the pig bladder had several additional uses, all based on its properties as a lightweight, stretchable container that could be filled and tied off. The pig bladder has several traditional ceremonial uses in Europe, it is traditional during the festival Fasching in Bad Aussee to brandish inflated pig bladders on sticks. In Xinzo de Limia, inflated pig bladders are carried during Carnival. See Clown society and Jester and Gigantes y cabezudos and Vejigante. In traditional Germanic communities a public Schlachtfest is announced by hanging the pig's inflated bladder in front of the host establishment; the bladder is used as a casing for several traditional food items, including the sausages known as ventricina and sobrassada. The pig bladder was used in sports, as the airtight membrane inside a football. In the early 19th century the inventor William Gilbert used pig bladders in the manufacture of rugby balls.
Decades Richard Lindon did the same. For centuries before the invention of the paint tube, artists used to store their paints in pig bladders; when the artist was ready to use the paint, they would puncture a hole in the bladder and squeeze out the desired amount of paint. They would have to mend the hole when finished and the whole process was quite messy; the oil paint tube was invented in 1841, as the primary packaging of paints for transport and storage. In the bian lian style of Chinese opera, painted pig bladders were used as face masks.

A waterskin is a receptacle used to hold water. Made of a sheep or cow bladder, it retains water and therefore was useful in desert crossings until the invention of the canteen, it is still used in some developing nations. Though it may have been used over 5000 years ago by tribal peoples, the first pictures of it are from ancient Assyrians, who used the bladders as floats in 3000 B. C, it was used by large ancient empires such as Rome before the advent of the canteen. Modern waterskins are made of various plastic or rubber impregnated canvases, or sometimes thicker transparent plastics, are called water-pouches, water bags, or water bladders; such modern waterskins offer many features, such as detachable straw-hoses, refill openings of various widths, various closures and handles, styles of covering or cases, removable cases or carry pouches.
