From the rolling mill, aluminum foils emerge with a natural shiny finish, almost as bright as a mirror; they also can be produced with an as-rolled, satin-like finish called matte. Additionally, foil has all of the unique functional characteristics of the aluminum alloy from which it is made, since it is the solid metal.

Foils of aluminum are rolled from several different alloys. Because all of the alloys commonly made into foil contain more than 90% aluminum and retain most of its properties, all are correctly called aluminum foil.

Bare (plain), coated, or laminated, aluminum foil is the most effective material for the full range of flexible and other packaging forms employed to protect foods, drugs, cosmetics, and a lengthy list of other items.

Even in countries where modern markets are not common, people benefit daily from aluminum foil in such packages as flexible pouches and laminated fiber drums which contain many of the food, pharmaceutical, and other products they consume.

Add to the aforementioned packaging and insulation uses the literally millions of aluminum electrical capacitors for radios, televisions, and most other electronic or electrical devices. Many motors and transformers also use aluminum foil as coil-winding conductor.

In this single, abundantly available element we have a truly unique material in both proprieties and dimension. Moreover, aluminum products, including foil and cans, are recyclable at low energy cost.
