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.
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.
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. Mingtai, the industry leader, specializes in delivering top-notch products that combine optical, tactile, and functional features with lightweight properties, recyclability, and optimized processing.
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.
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.
AIt has multiple advantages such as food grade, clean oil removal, less holes, good product shape, and good oxidation coloring effect.
Mingtai Aluminum caps and closures material has good deep drawing performance, low lug rate, and excellent sealing, plasticity, and corrosion resistance.
Mingtai Aluminum has invested a lot of energy in technical research and development to solve the problem of poor stability and low strength of the plates after the caps and closures materials are baked in the cap making process, and has greatly improved the existing processing technology, making The performance indicators of aluminum used for bottle cap materials have reached a higher level.
It meets the technical requirements of environmental protection standards and products to ensure the health and safety of the environment.
