Coloring process

Frosting: A layer of frosted texture.

Outer spraying of the inner bottle: spraying on the outside of the inner bottle has a clear gap between the outer bottle and the outer bottle. From the side, the spray pattern is small. Inner spraying on the outer bottle: It is sprayed on the inner side of the outer bottle, which looks larger in appearance. The area is small when viewed from the vertical plane. And there is no gap with the inner bottle.


Printing process

1. Silkscreen: The effect after printing has obvious concavity and convexity. Because it is a layer of ink. The silk-screened regular bottles (cylindrical type) can be printed at one time. And it is divided into two types: self-drying ink and UV ink. The self-drying ink is easy to fall off for a long time and can be wiped off with alcohol. UV ink has obvious bumps to the touch and is difficult to wipe off.

2. Hot stamping: a thin layer of paper is stamped on it. So there is no bumpy feel of silkscreen. And hot-stamping is best not directly on the two materials of PE and PP.

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

4. Thermal transfer: Thermal transfer is mostly used for large-volume and complex printing products. It belongs to attaching a film on the surface. The price is too expensive.

5. Offset printing: widely used in the cosmetic tube.
