As one of the important fulcrums of cosmetics, color cosmetics have higher requirements on the visual effects and tactility of cosmetics. Compared with other packaging materials, color cosmetics have stricter requirements on the craftsmanship of cosmetic packaging materials.
The design process of cosmetic packaging materials is an important part of the cosmetics market, and cannot be omitted. At present, the main processes of cosmetic packaging materials on the market include: electroplating, silk screen printing, hot stamping, surface spraying, UV, thermal transfer, spraying sand. Then everyone follows Yusu Packaging to analyze the mainstream process of cosmetic packaging materials:
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:
1. There should be a good bonding force between the plating layer and the base metal, and between the plating layer and the plating layer.
2. The coating should be finely crystalline, smooth and uniform in thickness.
3. The coating should have a specified thickness and as few pores as possible.
4. The coating should have all the specified indexes, 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 pictures and texts. Screen printing consists of five major 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 position on the screen printing plate, and at the same time move toward the other end of the screen printing plate at a uniform speed, the ink is moved by the squeegee from the image and text Part of the mesh is squeezed onto the substrate.
