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.
A foil is a very thin sheet of metal, typically made by hammering or rolling. [ 1 ] [ 2 ] Foils are most easily made with malleable metal, such as aluminium , copper , [ 3 ] tin , and gold . Foils usually bend under their own weight and can be torn easily. [ 2 ]
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.
Although aluminium is unlikely to be adsorbed into the blood stream, its inhalation can cause severe irritation and hinder the ventilation mechanism. [9] High levels of exposure over many years may result in aluminosis which causes pulmonary fibrosis. [10] Aluminium powder and dust is highly flammable and creates a significant risk of fire or ...
Tin foil, also spelled tinfoil, is a thin foil made of tin. Tin foil was superseded after World War II by cheaper and more durable [ 1 ] aluminium foil , which is still referred to as "tin foil" in many regions (an example of a misnomer ).

Metal roofs are 100% recyclable and can be made from other recycled products. Asphalt shingles are petroleum based with other chemicals making their recycling process more toxic, most shingles are not recycled and 20 billion pounds (9.1 million tonnes) are sent to landfills every year and take hundreds of years to decompose.
