In fact, household foils for food cooking and food freezing have certain requirements for pinholes, while household foils for beauty salons and household foils for home decoration have looser requirements for pinholes. The general standard for aluminum foil GB/T 3198-2020 "Aluminum and Aluminum Common grade of pinholes in "Alloy Foil" can meet the needs of use, that is, the requirements for pinholes in aluminum foil with a thickness of 0.0068mm~0.0070mm are ≤500 pieces/m2, and the requirements for pinholes in aluminum foil with a thickness of 0.0070mm~0.0090mm are ≤200 pieces/m2. 0.0090mm~0.0120mm thick aluminum foil pinholes are required to be ≤100 pieces/m2. Therefore, the thickness specification of 0.0068mm ~ 0.0080mm household foil pinhole requirements is equivalent to GB/T 3198-2020 "aluminum and aluminum alloy foil".

In addition, GB/T 3198-2020 "Aluminum and Aluminum Alloy Foils" requires 0 pinholes for aluminum foils with a thickness of 0.0400mm to 0.0500mm, and the requirements for household foils should not be lower than the general standards for aluminum foils GB/T 3198-2020 "Aluminum and aluminum foils". Aluminum alloy foil", so the pinhole requirement for household foils with a thickness of 0.0400mm to 0.0500mm is 0.
