Aluminium Closure Sheet for Bottle Cap

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

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

Specifications of aluminum bottle cap material

Material requirements: The aluminum closure sheet is straight, without rolling marks, scratches and stains.

Alloys : 8011, 3003, 30105, 1060

Specification: General thickness 0.20mm-0.23mm, width 449mm-796mm.

Production process: Aluminum bottle cap materials are made of hot-rolled or continuous casting and rolling billets, and then cold-rolled.

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 personalization. Aluminum bottle caps are not only mechanized and scaled, but also low-cost, pollution-free, and recyclable. Therefore, we can foresee that aluminum bottle caps will still be the mainstream in the future wine bottle caps.

Aluminum-plastic caps

The main components of aluminum-plastic combination cap are aluminum alloy and plastic material, which are made into bottle caps through special processes.

Excellent performance is the basis of medical applications. The aluminum-plastic composite bottle cap is thin and easy to open. It is widely used in pharmaceutical oral liquid bottle caps. It also plays its advantages to seal bottled liquids such as antibiotics and infusions. At the same time, the aluminum-plastic composite cap has a simple structure, low cost, good sealing, and is more convenient to use. The simple and common method of producing these bottle caps is injection molding.

8011 aluminum foil

The main elements of 8011 aluminum for bottle cap are Al-Fe-Si, and the rest are trace impurity elements. Its performance is better than pure aluminum foil. 8011 aluminum foil is the main material for PP/ROPP bottle caps. 8011-H18 aluminum foil is mainly used for stamping shallow caps and 8011-H16 aluminum foil is hot rolled and is mainly used for aluminum anti-theft bottle caps.
