ALUMINIUM FOIL TAPE  is usually made with aluminum, but some foil tapes use lead or copper backings instead. Some foil tape varieties also contain glass, tin plating, or steel. The metal in foil tape gives it extra durability compared to plastic-based tapes. Most foil tapes can withstand temperatures between -30°F and 80 °F. Since all the metals used in foil tape are relatively soft, the tape is highly malleable. The best foil tape combines the flexibility and protective qualities of aluminum, copper, and lead foil with a top-notch adhesive.
