Properties of Aluminium Closure Sheet

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.

Aluminium Closure Sheet – The ideal material for the production of bottle closures:

• is light weight
• is easily and economically recycled
• has superior barrier qualities
• has good formability
• offers a bright finish for decoration.

Haomei Aluminium Closure Sheets are suitable for both transparent and non-transparent lacquering, and will not bend during curing process. For applications requiring deep drawing, such as long caps, Haomei aluminium closure sheets show very low earing, greatly reducing scrap rate for our clients.
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.
