The 30×60mm aluminum wine screw cap is a common bottle sealing accessory. The 30 mm typically refers to the bottle cap's outer diameter, and the 60 mm refers to its height. 30x60mm aluminum wine screw caps conforms to the international wine industry standard for 750mL bottles (such as the LA28-20 bottle neck) and is compatible with screw-sealing structures.

The 30×60 mm aluminum wine screw cap is made of 8011 aluminum alloy (such as H14 hot-rolled aluminum), which is corrosion-resistant, oxidation-resistant, lightweight, and has excellent sealing properties. It effectively protects the liquid inside the bottle, preventing its quality and taste from being affected by the cap material. Aluminum screw caps are suitable for low-permeability packaging applications such as wine, spirits, and drinking water. Aluminum is recyclable, aligning with environmental trends and helping companies establish a sustainable brand image.
