Alumiinifolio voidaan jakaa paksuun kalvoon, yksittäiseen nollakalvoon ja kaksinkertaiseen nollakalvoon paksuuserojen mukaan.
① Paksu kalvo: Kalvo, jonka paksuus on 0.1-0,2 mm.
② Keskikokoinen kalvo: kalvot, joiden paksuus on enintään 0,01 mm.
③ Double zero foil: The so-called double zero foil refers to the foil with two zeros after the decimal point when its thickness is measured in millimeters. It is usually aluminum foil with a thickness less than 0.01, that is, aluminum foil with a thickness of 0.005-0.009mm. Aluminum foil with a thickness of ≤ 40ltm is sometimes referred to as "light gauge foil" in foreign countries, while aluminum foil with a thickness of>40btm on yhteisnimitys "heavy gauge foil".
