We could treat 3105 Aluminum screw cap 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 earring rate.
With our good flatness and squareness, the issues of color gapping, unevenness or print misalignment during printing can be prevented.

Compare with 8011 closure sheet, 3105 aluminium screw cap 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.
