Many people may don’t know much about the use of color mark at the end of cosmetic tube, so today I would like to tell you what kind of use cosmetic tube color mark have?
The color bar at the end of the tube is actually called "eye fixation point", which is used for positioning and identification of the end sealing of products in the production process of cosmetic tube. The commonly used color strips include red, blue, green and black. The electric eye positioning function is very common in printing tube-type packaging, which is used for sealing the tail machine positioning application after the production is completed and the tube is filled automatically. After charging, the tube is placed in the automatic sealing machine. The machine senses relevant color mark and begins to seal the tube automatically, so as to ensure that the packing is in the correct position when sealing the end. The color mark on the end of cosmetic tube is mainly used for positioning and identification of the end sealing of toothpaste filling, which is called electric eye fixation point in the industry. Electrical eye fixation point is very common in tube packing, and it is widely used in tube packing products, such as cosmetics, food, etc. It is used for positioning induction of the sealing machine after automatic filling of the product to ensure that the packing is in the correct position when sealing the end.
For many pseudo-experts, the color mark of the end of the cosmetic tube corresponds to the difference of the internal products, which is completely wrong. The color mark of the end of the tube simply seals the end of the tube with a mark.
