Alumiinifolion paksuuden luokitus

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