Aluminum plated films are usually used on packages with barrier or light shielding requirements. Therefore, the thickness, surface condition and adhesion fastness of the aluminum plated layer will directly affect the above properties.

Aluminum vapor deposition equipmentAt present, the vacuum aluminum plating equipment used for plastic film in the market mainly has two types: winding type and suspension type.

Aluminum coated substrateDue to the particularity of the vacuum evaporation process, it has the following requirements for the film substrate to be plated.

Vacuum evaporation of metal thin film is a process of forming composite thin film by melting and vaporizing metal under high vacuum (above 10-4mba) by resistance, high frequency or electron beam heating, and adhering to the surface of thin film substrate.

According to the data released by China's National Bureau of statistics, China's aluminum production fell for the third consecutive month in July, and the average daily production hit the lowest level since October 2020.

1. Anodic oxidation: on the surface of aluminum, a layer of alumina would be produced through electrochemical principle. This oxide film has special properties such as protection, decoration, insulation and wear resistanceTechnical features:1. Strength of the lift,2. All colors are available, excep
