In recent years, aluminum alloy bottle caps have been increasingly used in people's daily lives, especially in the packaging of alcohol, beverages, and medicines.

Aluminum bottle caps have simple shapes and fine production. Advanced printing technology can achieve consistent colors and exquisite patterns, giving consumers an elegant visual experience. In addition, aluminum bottle caps have good sealing performance, excellent performance and More and more applications.

Aluminum bottle caps are mostly processed on production lines with a high degree of automation, so the requirements for material strength, elongation, dimensional deviation, etc. are very strict, otherwise breaks or creases will occur during the processing.

Generally, the alloys used for aluminum alloy bottle cap materials include 8011 alloy, 3003 alloy and 3004 alloy. 1050 and 1060 alloys are also used. Which alloy aluminum sheet is selected according to the stretch length of different products.

Material requirements: The bottle cap material sheet should be straight and free of rolling marks, scratches and stains.

Common alloy states: 8011-H14, 3003-H16, etc.

Material specifications: general thickness 0.20mm-0.23mm, width 449mm-796mm.

Production process: Aluminum bottle cap materials are supplied by hot rolling or continuous casting and rolling, and then cold rolled. Domestic manufacturers that produce anti-theft cover materials mostly use continuous casting and rolling billets, whose performance is better than that of cast and rolled billets.

Due to the continuous innovation of technology, the functions and production forms of aluminum bottle caps are also developing in a diversified and personalized direction. Aluminum bottle caps are not only mechanized and large-scale, but also low-cost, pollution-free, and can be recycled. Therefore, in future wine bottle caps, we may foresee that aluminum bottle caps will still be the mainstream.
