Thickness
Aluminum foil can be classified into thick foil, single-zero foil and double-zero foil according to the difference in thickness.
①Heavy gauge foil: foil with a thickness of 0.1 to 0.2mm.
② single zero foil ("medium gauge foil"): thickness of 0.01mm and less than 0.1mm / the foil.
③ double-zero foil ("light gauge foil"): the so-called double-zero foil is in its thickness in mm as a unit of measurement after the decimal point has two zeroes of the foil, usually for the thickness of less than 0.01 of the foil, that is, 0.005 ~ 0.009mm of aluminum foil. Overseas sometimes the thickness of ≤ 40ltm aluminum foil called "light gauge foil", and the thickness of > 40btm aluminum foil collectively referred to as "heavy gauge foil".
