RE: is aluminum foil a pure substance - lolitahe69 - 12-06-2021 Aluminum Foil is made out of the element Aluminum. Aluminum foil is made from an aluminum alloy which contains between 92 and 99 percent aluminum. Aluminum foil is produced by rolling aluminum slabs cast from molten aluminum in a rolling mill to the desired thickness. Aluminum foil provides a complete barrier to light, oxygen, moisture and bacteria. For this reason, foil is used extensively in food and pharmaceutical packaging. These foils are pure and sometimes they are made stronger by incorporating other materials. Thin foils are fragile and are sometimes laminated with other materials such as plastics or paper to make them stronger and more useful. Metallised films are sometimes mistaken for aluminium foil, but are actually polymer films coated with a thin layer of aluminium.
