Aluminum is a common material for caps and closures
Aluminum bottle caps are made of high-quality special aluminum alloy materials and are mainly used for the packaging of wine, beverages (with or without steam) and medical and health care products, and can meet special requirements such as high-temperature cooking and sterilization. It is characterized by simple shape, fine production, consistent color and exquisite pattern by advanced printing technology. Compared with plastic bottle caps, it not only has better performance, but also has low cost, no pollution, and can be recycled.

Applications and Demands
Materials on caps and closures
Aluminum bottle caps are generally made of 8011, 1060, 1235, 3004, 3105 and other alloys. The material specifications generally have a thickness of 0.20-0.23mm, an allowable tolerance of ±0.01%, and a width of 449-796mm. Aluminum bottle caps are generally processed on a highly automated production line, so the requirements for the strength, elongation and dimensional deviation of the material are very strict, otherwise cracks or creases will occur during deep drawing. In order to ensure that the caps and closures are easy to print after forming, it is required that the caps and closures have a flat surface without rolling marks, scratches and stains.

1070 1080 5005 5657 aluminum coil sheet for cosmetic packaging
Creativity and elegance are projected as crucial attributes in cosmetics packaging, necessitating the use of high-quality coils and sheets with excellent surface characteristics and finishing properties. Haomei aluminium, the industry leader, specializes in delivering top-notch products that combine optical, tactile, and functional features with lightweight properties, recyclability, and optimized processing.

8011 Aluminum Foil for Milk Yogurt Cup Lid and Milk Powder Lid
The yogurt cover film is primarily composed of composite materials, featuring a polyester/aluminum foil/heat seal (PET/AL/PE, EVA) structure.

The 8011-O-temper aluminum foil possesses excellent qualities including minimal perforations, effective barrier and heat sealing capabilities, as well as a pristine surface. This food-grade product ensures safety and hygiene even when subjected to high temperatures during cooking.

Currently, the most ideal packaging material for food, in terms of moisture resistance and barrier performance, is the tearable cover made of aluminum foil. It surpasses traditional metal covers due to its convenience in opening without posing any risk of injury. The raw material for this easy-to-tear aluminum foil cover is the 8011-O alloy, which finds extensive application in various fields, including milk powder and canned food packaging, owing to its outstanding qualities.

8011 H14 H16 Aluminum for Wine Bottle Cap
Approximately half of the anti-theft covers used for wine bottles are composed of aluminum. These aluminum caps not only ensure an airtight seal for the product inside the bottle but also serve the purposes of anti-theft opening and security.

The 8011-H14 and 8011-16 aluminum foils serve as the primary materials for manufacturing the aluminum wine covers.
