Hermione Nov 16 2023

The greatest qualities of aluminium closure sheets are stretchability and paint adhesion, guaranteeing the highest quality printing of drawings and designs that can achieve various painted finishes on their market. The most commonly used alloy for aluminum closure plates for ROPP caps is 8011 alloy, which has good formability, good ear forming rate and flatness to ensure the deep drawing of long bottle caps. It usually uses ROPP caps such as bottle caps, aluminum liquid caps, red wine caps, anti-theft caps, perfume caps, skin care product caps, cosmetic caps, oil caps, aluminum caps, oral liquid plastic composite caps, infusion bottle aluminum plastic caps, etc.
