We could treat 3105 Aluminium 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 earing rate.
With our good flatness and squareness, we could prevent color gapping, unevenness or print misalignment during printing.
a. Plain mill finish Aluminium strip;
