With the continuous development of cosmetic industry, cosmetic packaging materials have become more and more important, especially the application of aluminium cosmetic containers in cosmetic packaging materials.
Because of its high strength/component ratio, easy forming and excellent physical and chemical functions, aluminium alloy materials have become the second largest category of metal materials used in industry, which is second only to iron and steel. Anodizing is the most basic and common method of surface treatment of aluminium alloy in modern times, which makes aluminium alloy materials more stable, more easy to use in the decorative and cosmetic packaging materials, especially in the high-end products packaging.
