3105 Aluminium closure sheet is used for the bottle cap market. Using a unique rolling technology, Haomei supplies aluminium sheets ideally suited to manufacture the caps for long neck wine bottles, extremely deep drawn and decorated closures, plus a range of pilfer proof caps for beverage bottles, soft drink, juice, isotonic beverage, energy beverage, and other products, such as the 30×60 mm specifications are often used in the wine and spirits segment.
Haomei Aluminum closure sheet is rolled to very fine tolerances to yield more closure per tonne of stock and to allow uninterrupted operation of high-speed, multiple-cavity presses. Its strength, high formability, low earring and printable surfaces make it ideal for pilfer-proof caps and vial seals.
