Aluminum Foil Is Classified According To Surface Condition

Aluminum foil can be divided into single-sided glossy aluminum foil and double-sided glossy aluminum foil according to surface condition.
① Single sided glossy aluminum foil: Double rolled aluminum foil, with one side shiny and one side turning black after being rolled, is called single-sided glossy aluminum foil. The thickness of aluminum foil on one side usually does not exceed 0.025mm.
② Double sided glossy aluminum foil: A single rolled aluminum foil with two sides in contact with the rolling mill. The two sides of the aluminum foil are divided into mirror two sided glossy aluminum foil and ordinary two sided glossy aluminum foil due to different surface roughness of the rolling mill. The thickness of double-sided aluminum foil is generally not less than 0.01mm.
