2023-02-08

Aluminum bottle caps are made of high quality clear lacquer aluminum coil and sheet for pilfer proof caps 3105 and 8011, which are mainly used for the packaging of wine, beverages (with or without steam) oral liquids and medical and health care products, and can meet special requirements such as high-temperature cooking and sterilization . Most of the wine packaging bottle caps are made of aluminum caps, which are characterized by simple appearance, fine production, and advanced printing technology to make them consistent in color and exquisite in design. Compared with plastic bottle caps, aluminum bottle caps not only have better performance, but also have low cost, no pollution, and can be recycled.

Aluminum bottle caps are mostly processed in a production line with a high degree of automation, so the requirements for the strength, elongation and dimensional deviation of the lacquer aluminum coil and sheet for pilfer proof caps are very strict, otherwise cracks or creases will occur during processing. In order to ensure the convenience of printing after the bottle cap is formed, the surface of the aluminum sheet for caps material is required to be flat, without rolling marks, scratches and stains. The alloys of lacquer aluminum for pilfer proof caps generally used are 8011-H14, 3105-H14, etc., and the thickness of the material specification is generally 0.20mm-0.23mm, allowable tolerance ±0.1%, width 449mm-796mm. The production of aluminum coil and sheet for bottle caps can be made by hot rolling or continuous casting and rolling, respectively, and then rolled by cold rolling. At present, lacquered aluminum coil and sheet for pp caps manufacturers use continuous casting and rolling billets for production, but according to reports from aluminum closure sheet manufacturers, hot-rolled billets are better than cast-rolled billets in terms of the use effect of anti-theft cover materials.

At present, the lacquer aluminum coil and sheet for pilfer proof caps are used for making bottle caps of many high end wines bottle seal, and the proportion of aluminum caps is very high. The reasons for this are as follows:

1. Compared with other bottle caps, it has more advantages in price. The production process of aluminum caps is simple, and the price of aluminum raw materials is low. the

2. Wine bottle aluminum cap packaging has marketing support, and is deeply loved by people because of its convenient use, promotion, improved packaging and diversification.

3. The sealing performance of aluminum caps is stronger than that of plastic caps, which is perfect for wine packaging. the

4. In terms of appearance, the aluminum caps can also be very beautiful, which makes the product more textured.

5. The wine bottle aluminum cap packaging has an anti-theft function, which can prevent unpacking and counterfeiting, and ensure the quality of the product.

The above five points are the main reasons why the wine packaging industry uses aluminum caps.
