Klasifikasi Ketebalan Kerajang Aluminium

Kerajang aluminium boleh dibahagikan kepada kerajang tebal, kerajang sifar tunggal, dan kerajang sifar berganda mengikut perbezaan ketebalan.
① Kerajang tolok berat: kerajang dengan ketebalan 0.1-0.2mm.
② Kerajang tolok sederhana: kerajang dengan ketebalan {{0}}.01mm dan kurang daripada 0.1mm/j.
③ Double zero foil: The so-called double zero foil is a foil with two zeros after the decimal point when its thickness is measured in millimeters, usually aluminum foil with a thickness less than 0.01, that is, aluminum foil with a thickness of 0.005~0.009mm. Sometimes in foreign countries, aluminum foil with a thickness ≤ 40ltm is referred to as "light gauge foil", while aluminum foil with a thickness>40btm secara kolektif dirujuk sebagai "kerajang tolok berat".
