General Details
Aluminum foil is prepared in thin sheets and is used in a multitude of products from everyday household foil to industrial applications. Aluminum foil is extremely pliable and can be bent or wrapped around objects with ease. Typical finishes are available in pack rolled (one side bright/one side matte), two sides bright and mill finish. Millions of tons of aluminum foil are used throughout the world to protect and package foods, cosmetics and chemical products.
