Aluminum Foil Thickness Differences Can Be Divided Into Three Categories
① thicker foil ("heavy gaugefoil"): 0.1~0.2mm thick foil.
② single zero foil ("medium gauge foil"): the foil thickness of 0.01mm and less than 0.1mm/.
③ double zero aluminum foil ("light gauge foil"): so-called double zero aluminum foil is its thickness measured in mm as unit has two zeros after the decimal point when foil, usually aluminum foil of thickness is less than 0.01, 0.005~0.009mm aluminium foil. Abroad sometimes called 40ltm in thickness of aluminum foil "light gauge foil", while >40btm aluminum foil thickness are collectively referred to as "heavy gauge foil".
