In recent years, aluminum bottle caps have been used more and more in people's daily life, especially in the packaging of wine and beverages.
Aluminum bottle caps are simple in shape and finely crafted. Advanced printing technology can achieve consistent colors and exquisite patterns, bringing 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 a highly automated production line, so the requirements for the strength, elongation and dimensional deviation of the material are very strict, otherwise, they will break or crease during processing.
Material requirements: The bottle cap material board is straight, without rolling marks, scratches and stains.
Common alloy states: 8011-H14, 3003-H16, etc.
Material specifications: the general thickness is 0.20mm-0.23mm, and the width is 449mm-796mm.
Production process: The aluminum bottle cap material is made by hot rolling or continuous casting and rolling, and then cold rolling. Domestic manufacturers of anti-theft cover materials mostly use continuous casting and rolling billets, and their performance is better than that of casting and rolling billets.
Due to the continuous innovation of technology, the functions and production forms of aluminum bottle caps are also developing in the direction of diversification and individualization. Aluminum bottle caps are not only mechanized and large-scale, but also low in cost, pollution-free, and recyclable. Therefore, in the future wine bottle caps, we may foresee that aluminum bottle caps will still be the mainstream.
