The knowledge of aluminum closures

July 19, 2024

Wine caps, especially aluminum wine caps, occupy an important position in wine packaging due to their excellent performance and cost-effectiveness.

Aluminum wine caps have strict standards for material strength, elongation and dimensional deviation due to their high automation processing requirements. These wine caps usually use alloy states such as 8011-H14 and 3003-H16, with a thickness generally between 0.20mm and 0.23mm and a width of 449mm to 796mm. The production process of aluminum bottle caps includes hot rolling or continuous casting and rolling, and then cold rolling. At present, the demand for anti-theft bottle caps in my country is growing rapidly, especially aluminum bottle caps, which have obvious advantages over plastic bottle caps due to their good performance, low cost, pollution-free and recyclable. Aluminum bottle caps are widely used in wine packaging. Most wine packaging that uses aluminum bottle caps in the world is famous for its simple appearance and fine production. It uses advanced printing technology to achieve consistent color and exquisite patterns. ‌

In addition, the color and material of the wine cap not only affect the beauty of the packaging, but also the preservation and quality of the wine. ‌For example, the use of metal screw caps, although not well known in China, can actually effectively prevent bacteria from entering and maintain the fruity taste and freshness of the wine. ‌The use of this kind of cap allows high-end red wine to avoid the problem of cork contamination during storage. As long as it is stored properly (such as away from light and low temperature), it can theoretically be stored for a long time. ‌

The small holes on the wine cap (i.e. the seal on the wine bottle) also have their specific uses. ‌These small holes not only help exhaust and prevent the air between the wine cap and the bottle mouth from forming an air cushion, which affects the appearance, but also allow a proper amount of oxygen to enter, which helps soften the tannins and make the wine softer and more delicate. ‌
