Update time : 2023-06-02 15:32:43

Many people are not very familiar with the purpose of the color code at the end of the cosmetic tube, so today I will tell you what the purpose of the color code of the cosmetic tube is.

The color bar at the bottom of the package is actually called "electric eye positioning point", which is used for positioning and identification when the product is sealed during the production of cosmetic tubes. Commonly used are red, blue, green and black. The electric eye positioning function is very common in printing tube packaging. It is used for positioning sensing of the sealing machine after the product is completed and the tube is automatically filled. After the filling is completed, the tube is placed on the automatic sealing machine. The machine senses the relevant color point and starts to automatically seal the tube to ensure that the package is in the correct position when sealing. The color code on the bottom of the cosmetic tube is mainly used for positioning and identification when filling and sealing toothpaste, which is called the electric eye positioning point in the industry. The electric eye positioning point is very common in tube packaging, and is widely used in tube packaging products, such as cosmetics and food. It is used for position sensing of the sealing machine after the product is automatically filled to ensure that the package is in the correct position when sealing.

For many pseudo-experts who say that the color of the color code at the end of the cosmetic tube corresponds to the difference in the internal material, it is completely wrong to tell everyone here that the color code at the end of the tube is only a mark for the end of the tube.
