Cosmetic bottle refers to a kind of gas that can isolate the gas from the outside temperature. Container or a container to isolate external bacteria."

Beautiful things often attract people’s attention, especially for cosmetic bottles, because when we see cosmetics, the first thing we see is its packaging and bottles. So intuitively speaking, cosmetic containers also directly affect us. First impression of cosmetics. Because many times we don't understand cosmetics itself, maybe what attracts us is only the packaging that likes it. This is especially true for female friends. Therefore, the cost of cosmetic containers is also quite high. In order to make the cosmetic containers well, after the design drawings are released, the person in charge must continue to go to the container factories to participate in the production of the containers. The division of labor is meticulous to the manufacture and color spraying of the bottle body (when the container is first shipped from the factory, the basic color is white or transparent, which also involves spraying the color of the container. They are all produced in different factories, but such a detailed division of labor It did not affect the efficiency, but greatly improved the production efficiency. It only took a few days to determine the design drawings, to make samples, and then to mass production.

Glass bottles are traditional packaging products. 80%-90% of glass packaging containers are glass bottles and cans. Metal ion colorants are usually used to produce emerald green, dark green, light cyan, and amber glass.
