Surface treatment process of cosmetic injection

When consumers buy products, they are often attracted by the beauty and color of the product packaging. Cosmetic packaging is no exception. If you want to highlight the novelty and bright spots of the product and improve its market competitiveness, you need to do a good job of the surface. Treatment processes, such as electroplating, screen printing, spraying, bronzing, thermal transfer, water transfer, etc., these processes will make the color, appearance, and feel of cosmetic injection packaging materials more textured and beautiful. The following Lisson cosmetic tube packaging will talk about the surface treatment process of cosmetic injection packaging materials.

The manufacturing process of cosmetic packaging materials is mainly divided into two processes: coloring and printing.

1. Coloring process

Anodized aluminum: aluminum exterior, wrapped with a layer of plastic on the inner layer.

Electroplating (UV): Compared with the spray image, the effect is brighter.

Spraying: Compared with electroplating, the color is dull.

Outer spraying of the inner bottle: spraying on the outside of the inner bottle, there is a clear gap between the outer bottle and the outer bottle, and the spraying area is small when viewed from the side.

Inner spraying on the outer bottle: It is sprayed on the inside of the outer bottle. The area looks larger from the appearance, and the area is smaller from the vertical plane, and there is no gap between the inner bottle and the inner bottle.

Brushed gold and silver: It is actually a film, and you can find the gaps in the bottle body by carefully observing it.

Secondary oxidation: the injection molding manufacturer performs secondary oxidation on the original oxide layer to achieve a pattern that is covered with a dull surface on a glossy surface or a pattern on a dull surface with a glossy surface, which is mostly used for logo production.

Injection color: Toner is added to the raw material when the product is injected. The process is relatively cheap, and bead powder can also be added. Adding Taibai fen will make the transparent color of PET become opaque.

2. Printing process

Silk screen: After printing, the effect has obvious concavity and convexity, because it is a layer of ink.

The regular bottle (cylindrical type) of silk screen printing can be finished at one time, and the other irregular one has a one-time cost, and the color is also a one-time cost, which is divided into two types: self-drying ink and UV ink.


Hot stamping: It is a thin layer of paper stamped on it, so there is no bumpy feeling of silk screen printing.

Hot stamping should not be directly applied to the two materials of PE and PP. You need to perform thermal transfer first and then hot stamping, or if you have good hot stamping paper, you can also directly hot stamp.

Water transfer printing: It is an irregular printing process carried out in water. The printed lines are inconsistent and the price is more expensive.

Thermal transfer: Thermal transfer is mostly used for large-volume, complex-printed products. It is a layer of film attached to the surface, and the price is relatively expensive.

Offset printing: It is mostly used for aluminum-plastic hoses and all-plastic hoses. If the offset printing is a colored hose, you must use silk screen printing. The offset printing will show the background color, and sometimes a bright film or sub-layer is attached to the surface of the hose. membrane.
