3105 aluminum sheet for screw cap
Compare with 8011 closure sheet, 3105 aluminum sheet has enough strength, so it is stronger enough to bear the gas pressure, so it is widely used for making screw cap for gas liquid bottle, such as soda water and carbonated wine.
We could treat 3105 aluminum sheet with phosphoric acid chromated, and DOS coated, printed with different colors, on the basis of our plain sheet.
We control the materials composition, rolling temperature and time,and annealing temperature to product optimal materials to meet client’s performance needs, such as its opening capability and earing rate.
With our good flatness and squareness, we could prevent color gapping, unevenness or print misalignment during printing.
