Aluminum foil for bottle cap is becoming more and more popular. It is mainly used for packaging of wine, food and beverages, cosmetics, etc. The bottle cap has the ability to keep the contents of the product tightly closed, and also has the function of anti-theft opeing, so the selection of aluminum foil for bottle cap is very important.
In order to ensure the convenience of printing after the bottle cap is formed, the surface of the aluminum foil roll is required to be flat, without rolling marks, scratches and stains. The alloy are 8011, 1060, 3105, 3003,etc. The allowable tolerance is ±0.1%, and the width is 449-796mm.
8011 aluminum foil has the advantages of clean surface degreasing, low ear rate, high cup convex value, high strength and good sealing performance, which is widely used in the fields of bottle cap packaging such as wine, beverages, medicine caps, cosmetics, etc.
8011 aluminum foil is the main material to make pilfer proof caps. In addition to the good deep drawing performance and low ear rate, the 8011 bottle cap material has a certain strength after work hardening. Its main alloying elements are Fe and Si, and the rest are trace impurity elements.
1060 aluminum alloy is used to make lid by combining with the plastic. Because the aluminum-plastic combined part will come into contact with the liquid in the bottle, most of them are used in the cosmetics industry, and some are used in the pharmaceutical industry.
When the bottle cap is used to package carbonated beverages, 3105 alloy must be used. The main metal element of 3105 aluminum alloy is Al-Mn. On the basis of 3003 aluminum alloy, Cu and Mg are added to increase the mechanical properties of the finished product. The alloy has higher strength than 3003.
