Large roll of Aluminium foil, with micrometer showing a thickness of 0.0005 inches (0.013mm) Aluminium foil (Known as Aluminum Foil in North America) is aluminium prepared in thin sheets (about 0.02 mm in thickness). As a result of this, the foil is extremely pliable, and can be bent or wrapped around objects with ease. Image File history File linksMetadata Aluminium_foil_micrometer. ...

Aluminium foil is sometimes known as al-foil or alu-foil. It is also often called tinfoil, although it is not made from tin, or as silver paper although it is not made from silver; or in North America, as Reynolds wrap after Reynolds Metals, the leading manufacturer when it was introduced on the American market (much to the chagrin of Alcoa, Reynolds' main competitor, which had its brand "Alcoa Wrap" referred to as "Alcoa Reynold's Wrap").[citation needed] General Name, Symbol, Number tin, Sn, 50 Chemical series poor metals Group, Period, Block 14, 5, p Appearance silvery lustrous gray Standard atomic weight 118. ...

History Foil made from a thin leaf of tin was commercially available before the aluminium counterpart. In the late 19th century and early 20th century, tin foil was in common use, and some people continue to refer to the new product by the name of the old one. Tin foil is stiffer than aluminium foil. It tends to give a slight tin taste to food wrapped in it, which is one major reason it has largely been supplanted by aluminium and other materials for wrapping food.

Tin was first replaced by aluminium in 1910, when the first aluminium foil rolling plant, “Dr. Lauber, Neher & Cie., Emmishofen.” was opened in Kreuzlingen, Switzerland.
The plant, owned by J.G. Neher & Sons (aluminium manufacturers) started in 1886 in Schaffhausen, Switzerland, at the foot of the Rhine Falls - capturing the falls’ energy to produce aluminium. Neher's sons together with Dr. Lauber discovered the endless rolling process and the use of aluminium foil as a protective barrier. From there began the wide use of aluminium foil in the packaging of chocolate bars and tobacco products. Processes evolved over time to include the use of print, color, lacquer, laminate and the embossing of the aluminium.[citation needed]
Properties
 Decorative aluminium foils Aluminium foil typically has a highly reflective side and a more matte side. This is a result of common manufacturing processes. As aluminium foil is easy to tear, the foil is sent through machines in pairs. The side where the aluminium foil was in contact with the other sheet is more matte than the exterior side. This difference in the finish has led to the perception that favoring a side has an effect when cooking. While many believe that the shiny side's reflective properties keep heat in when wrapped on the interior and keep heat out when facing exterior, the actual difference is imperceptible without instrumentation [1].

Uses
Food packaging Aluminium foil is used to make long life packs for drinks, dairy products, and many other sensitive foods. The foil acts as a complete barrier to light (which spoils fats), odours, loss or gain of moisture, and bacteria. Aluminium foil containers and trays are used to bake pies and to pack takeaway meals, ready snacks and long life pet foods. The word drink is primarily a verb, meaning to ingest liquids. ...

Aluminium foil is widely sold into the consumer market, usually in rolls of around 50 centimetres width and several metres in length. It is used for wrapping food in order to preserve it, for example when storing leftover food in a refrigerator (where it serves the additional purpose of preventing odour exchange), when taking sandwiches on a journey, or when selling some kinds of take-away or fast food. Mexican restaurants in the United States, for example, typically provide take-away burritos wrapped in aluminium foil. Consumers refers to individuals or households that purchase and use goods and services generated within the economy. ...

Insulation Aluminium foil is also widely used for thermal insulation (barrier and reflectivity), heat exchangers (heat conduction) and cable liners (barrier and electrical conductivity). Foils in special alloys are even used for structural honeycomb components for aircraft. Aluminium foil's heat conductive qualities make it a common accessory in hookah smoking: a sheet of perforated aluminium foil is frequently placed between the coal and the tobacco, allowing the tobacco to be heated without coming into direct contact with the burning coal. Thermal insulation on the Huygens probe The term thermal insulation can refer to materials used to reduce the rate of heat transfer, or the methods and processes used to reduce heat transfer. ...

In one year's April Fool's joke, a Dutch television news station reported that the government had introduced a new way to detect hidden televisions (in many countries in Europe, one must pay a television licence to fund public broadcasting) by simply driving through the streets with a new detector, and that the only way to keep one's television from being detected was to wrap it in aluminium foil.[citation needed] April Fools Day or All Fools Day, though not a holiday in its own right, is a notable day celebrated in many countries on 1 April. ...

Cooking Aluminium foil is also used for barbecuing more delicate foods such as mushrooms and vegetables; food is wrapped in foil then placed on the grill, preventing loss of moisture that may result in a less appealing texture. A barbecue in a public park in Australia A barbecue on a trailer at a block party in Kansas City Pans on the top shelf hold hamburgers and hot dogs that were grilled earlier when the coals were hot. ...
As is the case with all metallic items, aluminium foil reacts to being microwaved. This is due to the effect of electric fields of the microwaves causing a build up of charge to form between the sharp points in the aluminium; if enough charge accumulates it will discharge to a different place on the foil, creating a spark (i.e. arcing). Due to frequent use in food services, this commonly leads to kitchen fires[citation needed]. It has been suggested that this article be split into articles entitled Microwave oven and Microwave heating. ...
It is also unwise to cook a highly acidic food in an iron vessel, then cover the leftovers in aluminium foil, because if the foil touches the food, a simple battery is created. The foil rapidly dissolves into the food, leaving dull grey dregs. Look up battery in Wiktionary, the free dictionary. ...
Art and decoration Heavier foils made of aluminium are used for art, decoration, and crafts, especially in bright metallic colours. Metallic aluminium, normally silvery in colour, can be made to take on other colours through anodization. Anodizing creates an oxide layer on the aluminium surface that can accept coloured dyes or metallic salts, depending on the process used. In this way, aluminium is used to create an inexpensive gold foil that actually contains no gold, and many other bright metallic colours. These foils are sometimes used in distinctive packaging. Anodising is a process used to protect aluminium from corrosion. ...
Deterring pets Aluminium foil is also sometimes used in the training of cats; as cats have an inborn dislike of loud noise, like that caused by sheets of aluminium foil, it is possible to prevent cats from jumping on or otherwise damaging furniture by covering its surfaces. Though this could be seen as a questionable housekeeping manner. Binomial name Felis catus Linnaeus, 1758 Synonyms Felis lybica invalid junior synonym The cat (or domestic cat, house cat) is a small carnivorous mammal. ...
Criticism The extensive use of aluminium foil has been criticised by some environmentalists because of the high resource cost of extracting aluminium, primarily as a result of the large amount of electricity used to decompose bauxite. However, this cost is greatly reduced via recycling and the fact that many foods that would otherwise perish can be protected over long periods without refrigeration thanks to the total barrier properties of aluminium foil. Many aluminium foil products can be recycled at around 5% of the original energy cost[citation needed]. For the psychology topic, see Environmental psychology. ...
