Aluminiumfolie klassificeras efter tjocklek

Aluminiumfolie kan delas in i tjock folie, enkel nollfolie och dubbel nollfolie efter tjockleksskillnad.
(1) Heavy gaugefoil ("tung gaugefoil"): folie med en tjocklek på 0.1 ~ 0.2mm.
(2) "Medium gauge folie" : tjockleken på 0.01 mm och mindre än 0,1 mm/folie.
(3) Double zero foil (" light gauge foil ") : The so-called double zero foil is the foil with two zeros after the decimal point when its thickness is mm as the unit of measurement, usually the aluminum foil with a thickness of less than 0.01, that is, 0.005~0.009mm aluminum foil. Sometimes the thickness of ≤40ltm aluminum foil is called "light gauge foil", and the thickness of >40btm aluminiumfolie kallas gemensamt för "heavy gauge foil".
