Product Description

aluminium alloy sheet 3105 H14/H16 aluminium closure sheet for screw caps
Compared with aluminium bottle closure sheet, 3105 aluminium wine closure sheet for screw caps has sufficient strength, can withstand large gas pressure, in addition to 3105 aluminum alloy is particularly outstanding in acid resistance and corrosion resistance, so it can be widely used for screw caps of wine, spirits, and soda bottles. Besides, 3105 wine screw aluminium closures can also be well treated with chromic acid phosphate and DOS coating, being printed with colorful colors.

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.
