There has been such a message: "Check the toothpaste in your home immediately, if it is a black bar, throw it away! Only today did I know that the color bar has a meaning. When you buy toothpaste, please pay attention to the color bar at the bottom of the back, and try to choose the color bar as much as possible. Green and blue!"
In fact, not only toothpaste, but also many skin care products, cosmetics, pet supplies, ointments, etc. also have a black strip at the end of the packaging. There are black, red and other colors, so, as everyone thinks, is the black bar really bad?
The color bar at the bottom of the toothpaste package is actually called the "electric eye positioning point", which is used for the positioning and identification of the end of the product during the production of toothpaste. The commonly used ones are red, blue, green and black.
The electric eye positioning function is very common in printing tube packaging, and is used for the positioning sense of the sealing machine when the product is completed and the tube is automatically filled. After filling is completed, the hose is placed on the automatic end-sealing machine, and 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 the end is sealed. The color bar on the bottom of the pack has nothing to do with the ingredients of the product.
So which device pair to choose for marking and end capping?
