What Is Aluminum Foil? - haomeialu - 02-06-2018
Aluminum foil, or tin foil, is a paper-thin, shiny sheet of aluminum metal. It's made by rolling large slabs of aluminum until they are less than 0.2 mm thick.
It's used industrially for a variety of purposes, including packing, insulation and transportation. It's also widely available in grocery stores for household use.
At home, people use aluminum foil for food storage, to cover baking surfaces and to wrap foods, such as meats, to prevent them from losing moisture while cooking.
People may also use aluminum foil to wrap and protect more delicate foods, like vegetables, when grilling them.
Lastly, it can be used to line grill trays to keep things tidy and for scrubbing pans or grill grates to remove stubborn stains and residue.

Aluminium foil (or aluminum foil), often referred to with the misnomer tin foil, is aluminium prepared in thin metal leaves with a thickness less than 0.2 mm (7.9 mils); thinner gauges down to 6 micrometres (0.24 mils) are also commonly used.[1] In the United States, foils are commonly gauged in thousandths of an inch or mils. Standard household foil is typically 0.016 mm (0.63 mils) thick, and heavy duty household foil is typically 0.024 mm (0.94 mils). The foil is pliable, and can be readily bent or wrapped around objects. Thin foils are fragile and are sometimes laminated to other materials such as plastics or paper to make them more useful. Aluminium foil supplanted tin foil in the mid 20th century.
Annual production of aluminium foil was approximately 800,000 tonnes (880,000 tons) in Europe[1] and 600,000 tonnes (660,000 tons) in the U.S. in 2003.[2] Approximately 75% of aluminium foil is used for packaging of foods, cosmetics, and chemical products, and 25% used for industrial applications (e.g. thermal insulation, cables and electronics).[2] It can be recycled.
In North America, aluminium foil is known as aluminum foil. It was popularised by Reynolds Metals, the leading manufacturer in North America. In the United Kingdom and United States it is, informally, widely called tin foil, for historical reasons (similar to how aluminium cans are often still called "tin cans"). Metallised films are sometimes mistaken for aluminium foil, but are actually polymer films coated with a thin layer of aluminium. In Australia, aluminium foil is widely called alfoil.

Aluminum foil is a kind of rolled aluminum material. Aluminum foil is mainly for thickness. In the industry, aluminum products with a thickness of less than 0.2mm are usually called aluminum foil. Usually, the edges are slit and delivered in rolls. Aluminum foil is a soft metal film, which not only has the advantages of moisture-proof, air-tight, light-shielding, abrasion-resistant, fragrant, non-toxic and tasteless, but also because of its elegant silver-white luster, it is easy to process beautiful patterns and patterns of various colors. pattern.
According to the thickness, aluminum foil can be divided into double zero foil, single zero foil and thick foil. Double zero foil refers to the foil with two zeros after the decimal point when its thickness is measured in mm (ie thickness <0.01mm); similarly, single zero foil refers to a foil with one zero after the decimal point when the measurement unit is mm Foil (0.01mmâ¤thickness<0.1mm); thick foil refers to aluminum foil with a thickness between 0.1mm and 0.2mm.
Generally speaking, double-zero foil is mainly used for food packaging, cigarette packaging, electronic light foil, etc.; single zero foil is used for some food packaging, pharmaceutical packaging, electronic circuit signal shielding, air-conditioning foil, etc.; thick foil is mainly used for air-conditioning foil, Container foils, architectural decoration and industrial uses.
