8011 H14 Aluminum Closure Sheets
Aluminum Closure Sheets for bottle closure 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. Such closure sheet its strength, high formability, low Earring and printable surfaces make it ideal for pilfer-proof caps and vial seals.
