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
The adhesion requirements for household foils are described in two parts, 6.5.1 specifies all household foils, and 6.5.2 specifies only large die uncoated aluminum foils.
The standard GB/T 22638.5-2016 "Test Methods for Aluminum Foils - Part 5: Wetability Testing" was revised in 2016, and the water brushing test was changed to wettability. Wetting properties are similar to room temperature tensile mechanical properties and are specified only for large die uncoated aluminum foils.
The small tube core household foil roll diameter is small, and most of the products are directly sold as finished products. Therefore, the number of small tube core household foil joints is 0, that is, no joints are allowed. Other indicators were unchanged.
