Kerajang Aluminium Dikelaskan Mengikut Ketebalan

Kerajang aluminium boleh dibahagikan kepada kerajang tebal, kerajang sifar tunggal dan kerajang sifar berganda mengikut perbezaan ketebalan.
(1) Heavy gaugefoil (" heavy gaugefoil") : foil dengan ketebalan 0.1 ~ 0.2mm.
(2) "Kerajang tolok sederhana" : ketebalan 0.01mm dan kurang daripada 0.1mm/ kerajang.
(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 >Kerajang aluminium 40btm secara kolektif dirujuk sebagai "kerajang tolok berat".
