Aluminum Foils Product Description
Aluminum foil is a thin sheet of aluminum that is widely used in various applications due to its lightweight, malleability, and excellent barrier properties. It is produced by rolling aluminum ingots into thin sheets, which can be as thin as 0.2 mm. The foil is typically available in various thicknesses and widths, making it suitable for a range of uses, from household cooking to industrial applications. Its reflective surface also makes it an effective insulator, helping to retain heat and prevent moisture loss.
