Cosmetics, as one of the pillar industries of fast-moving consumer goods, consumers have become more aware and aware of it. Consumers no longer blindly follow the trend, and have higher requirements for cosmetics’ visual effects and touch. The craftsmanship of the material also has more stringent requirements.


The shape process of designing the packaging material is an important part before the launch of a cosmetic, and it cannot be omitted. The main cosmetic packaging process includes: electroplating, silk screen, bronzing, surface spraying, UV, thermal transfer, sandblasting.

1. Electroplating process


Electroplating process: Electroplating refers to a kind of plating that uses the base metal to be plated as the cathode in the salt solution containing the metal to be plated, and through electrolysis, the cations of the metal to be plated in the plating solution are deposited on the surface of the base metal to form a plating layer. 


Surface processing methods. The coating performance is different from the base metal and has new characteristics. According to the function of the coating, it is divided into protective coating, decorative coating and other functional coatings.


Electroplating process: generally includes three stages of pretreatment before electroplating, electroplating and post-plating treatment. Requirements for electroplating layer:


There should be good adhesion between the plating layer and the base metal, and between the plating layer and the plating layer.


The coating should be finely crystalline, smooth, and uniform in thickness.


The coating should have a specified thickness and as few pores as possible.


The plating layer should have various specifications, such as brightness, hardness, conductivity, etc.


2. Screen printing process


Screen printing refers to the use of silk screen as a plate base, and through the photosensitive plate making method, made into a screen printing plate with graphics and text. Screen printing is composed of five elements, screen printing plate, squeegee, ink, printing table and substrate. Use the basic principle that the mesh of the graphic part of the screen printing plate can penetrate the ink, and the mesh of the non-graphic part cannot penetrate the ink for printing. 


When printing, pour ink on one end of the screen printing plate, use a squeegee to apply a certain pressure to the ink part on the screen printing plate, and at the same time move to the other end of the screen printing plate at a uniform speed, the ink is moved by the squeegee from the graphic Part of the mesh is squeezed onto the substrate.

3. Hot stamping process


Hot stamping is a special printing process that does not use ink. The so-called hot stamping refers to the process of hot stamping the electrochemical aluminum foil onto the surface of the substrate under a certain temperature and pressure.
