The Evolution of Aluminum Foil Rolling Technology for Massive Outputs
This Is Why Single Side Bright Aluminum Foil Is Shiny On One Side And Dull On The Other.
Double-rolled aluminum foil is called one-sided aluminum foil when one side is shiny and the other side is opaque. The thickness of one-sided aluminum foil usually does not exceed 0.025mm.
Single Side Bright Aluminum Foil Roll
Why is it bright on one side and dull on the other?
It's all about the manufacturing process.
Aluminum foil is formed by repeated pressing using highly polished steel rolls. As the foils get thinner, two layers of foil are usually rolled stacking together to achieve the desired thickness and prevent the sheet from cracking.
The two surfaces that are in contact with the steel roll are glossy, while the two surfaces where the two layers of aluminum foil are in contact with each other are matte.
