Aluminium foil (or aluminum foil in American English; occasionally called tin foil) is aluminium prepared in thin metal leaves. The foil is pliable and can be readily bent or wrapped around objects. Thin foils are fragile and are sometimes laminated with other materials such as plastics or paper to make them stronger and more useful.
Aluminium (or aluminum) metal is very rare in native form, and the process to refine it from ores is complex, so for most of human history it was unknown. However, the compound alum has been known since the 5th century BCE and was used extensively by the ancients for dyeing .
Reynolds Metals created the first high-speed, gravure-printed foil, aluminum bottle labels, heat-sealed foil bags for foods and foil-laminated building insulation paper. In 1940, Reynolds Metals began mining bauxite (aluminum ore) in Bauxite, Arkansas, and opened its first aluminum plant near Sheffield, Alabama, the following year. In 1947, the ...
Parkesine, the first member of the Celluloid class of compounds and considered the first man-made plastic, is patented by Alexander Parkes. [4] 1869: John Wesley Hyatt discovers a method to simplify the production of celluloid, making industrial production possible. 1872: PVC was accidentally synthesized in 1872 by German chemist Eugen Baumann ...
Paper/foil/LDPE; Aluminium foil/paper/LDPE; PE/aluminium foil/paper; PET/aluminium foil/LDPE; Apart from these nylon, EVOH, EAA, PA, EVA, SiO2 plasma coatings are also used in laminates to give various functional properties. The layer combinations are selected by the engineer depending on the product characteristic, shelf life and extent of ...
Global bottled water giants are ramping up trials of easily recyclable aluminium cans to replace plastic that pollutes the world's seas. Aluminium cans might indeed mean less ocean waste, but they ...
Aluminium (or aluminum in North American English) is a chemical element; it has symbol Al and atomic number 13. Aluminium has a density lower than that of other common metals, about one-third that of steel. It has a great affinity towards oxygen, forming a protective layer of oxide on the surface when exposed to air.
Metallised films have a reflective silvery surface similar to aluminium foil and are highly flammable. The coating also reduces the permeability of the film to light, water and oxygen. The properties of the film remain, such as higher toughness, the ability to be heat sealed, and a lower density at a lower cost than an aluminium foil.
