aluminum strip for Cosmetic cap

The aluminum bottle cap is a new type of packaging material that is popular in the domestic and international markets. Compared with the traditional plastic or tinplate cap, the aluminum cap has good sealing performance, high pressure resistance, corrosion resistance, beautiful appearance and environmental protection. At present, the domestic aluminum cosmetic caps mainly use aluminum and aluminum alloys such as 1060, 1050, 1070，5005, etc., and there are generally shortcomings such as darkening effect, high ear-making rate and easy-breaking of the base cover after anodizing. The quality of aluminum cosmetic caps is at the low-end level and cannot meet the requirements of quality.
In order to solve the above problems, the aluminum material provided by Henan Signi Aluminum Co., Ltd. can make the caps of cosmetics with smooth surface, stable performance and easy stamping, and is used for manufacturing high-grade cosmetic caps.
1070 aluminum strip for cosmetic cap t he milling process is different from the conventional process, which increases the amount of milling surface and increases the amount of milling surface by 10~15mm/side. Vacuum annealing is different from previous annealing processes. After optimization of process parameters of several key processes such as milling, hot milk, intermediate annealing and cold concentrate, an aluminum strip with a thickness of 0.2-1.2_ is obtained, after mechanical properties test, cupping test, anodizing and other tests. The elongation of the material, the punching performance, the earing rate, and the anodizing effect are obvious.
1070 aluminum strip for cosmetic cap has excellent characteristics such as smooth surface, bright mechanical properties, accurate dimensional tolerance, easy stamping, small ear production after punching into a bottle cap, and good anodizing effect. It is suitable for manufacturing high-grade cosmetic bottle caps.
