As a part of packaging, the anti-counterfeiting function and production form of wine bottle caps are also developing towards diversification, and multiple anti-counterfeiting wine bottle caps are widely used by manufacturers. Although the functions of wine bottle caps on the market are constantly changing, there are two main types of materials used, namely aluminum and plastic. In recent years, due to the media exposure of plasticizers, aluminum caps have become the mainstream. Internationally, most alcohol packaging bottle caps also use aluminum caps. Due to the simple shape, fine production and scientific printing technology, aluminum caps can meet the requirements of uniform color, exquisite patterns and other effects, bringing consumers an elegant visual experience. Therefore, it has superior performance and wide application.
The aluminum cover is made of high-quality special aluminum alloy materials, which is mainly used for the packaging of alcohol, beverages (containing gas, not containing gas) and medical and health products, and can meet the special requirements of high-temperature cooking and sterilization.
Most aluminum covers are processed on production lines with high degree of automation, so the requirements for strength, elongation and dimensional deviation of materials are very strict, otherwise cracks or creases will occur during processing. In order to ensure that the aluminum cap is easy to print after forming, it is required that the sheet surface of the cap material should be flat and free of rolling marks, scratches and stains. Due to the high requirements for aluminum bottle caps, there are few mature aluminum processing manufacturers in the domestic market at present. As far as the current market distribution is concerned, the market share of aluminum caps is relatively large, accounting for more than half of the market share of wine bottle caps, and there is a significant growth trend. The market share of medical aluminum bottle caps is more than 85%, winning the favor of cap manufacturers with significant advantages and good market reputation.
The aluminum cover can not only be manufactured mechanically and on a large scale, but also has low cost, no pollution and can be recycled. Therefore, it is widely believed in the industry that aluminum caps will still be the mainstream of wine bottle caps in the future.
