Do you know what crafts can be done in glass bottles of skin care products?

The process of packaging materials can be simply divided into two categories: coloring process and printing process.

First, the coloring process of glass bottles of skin care products

1. Anodized aluminum: The aluminum exterior is wrapped in the inner plastic layer.

2. Electroplating (UV): Compared with spraying, the effect is bright.

3. Spraying: Compared with electroplating, the color that comes out is dull and matte.

4. Frosting: A layer of frosted texture.

5. Inner bottle and outer spray: It is sprayed on the outside of the inner bottle. There is a clear gap between the outer bottle and the outer bottle. The spraying area is small when viewed from the side.

6. Spraying inside the outer bottle: It is spraying on the inner side of the outer bottle, which looks large in appearance and small in vertical plane, and has no gap with the inner bottle.

7. Brushed gold and silver: It is actually a film. If you observe carefully, you can find the connection gap on the bottle.

8. Secondary oxidation: secondary oxidation is carried out on the basis of the original oxide layer, so as to achieve a pattern with a matte surface covered on a smooth surface or a pattern with a smooth surface on the matte surface, which is mostly used for the production of logos.

9. Injection molding color: Toner is added to the raw material when the product is injection molded, and the process is relatively cheap. You can also add pearl powder, or add too white powder to make the PET transparent color become opaque (add some toner to color). The generation of water ripples is related to the amount of bead powder added.

Second, packaging material printing process

1. Silk screen printing: The effect after printing has obvious bumps because it is a layer of ink. Regular bottles (cylindrical) for silk screen printing can be printed at one time; other irregular bottles are charged at one time. Color is also a one-time fee, and it is divided into self-drying ink and UV ink. Self-drying ink is easy to fall off for a long time. It can be wiped off with alcohol. UV ink has obvious bumps and it is difficult to wipe off.

2. Hot stamping: It is hot stamped with a thin layer of paper, so there is no concave and convex feeling of silk screen printing, and hot stamping is best not directly on PE and PP materials, it needs to be hot stamped first. Then hot stamping, or good hot stamping paper can also be hot stamped directly. Hot stamping cannot be done on aluminum plastic, but hot stamping can be done on all plastic.

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

4. Thermal transfer printing: Thermal transfer printing is mostly used for products with large quantities and complex printing, which belong to attaching a layer of film to the surface. Expensive.

5. Offset printing: mostly used for aluminum-plastic hoses and all-plastic hoses. If the offset printing is a white color hose, you must use silk screen printing, the offset printing will have the background color showing through. And sometimes a layer of bright film or sub-film is attached to the surface of the hose.
