Aluminiumsfolie kan opdeles i tyk folie, enkelt nul folie og dobbelt nul folie i henhold til tykkelsesforskelle.
① Heavy gauge folie: En folie med en tykkelse på 0.1-0,2 mm.
② Medium gauge folie: folier med en tykkelse på 0,01 mm eller mindre.
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 omtales samlet som "heavy gauge folie".
