What does the color of the "toothpaste tail" mean?

The color bar at the bottom of the toothpaste package is used for positioning and identification of product sealing during the toothpaste production process.

The China Oral Cleansing and Care Products Industry Association issued a statement on its website stating that the color bar at the bottom of the toothpaste package is used for positioning and identification of the product during the toothpaste production process, and is called the electric eye positioning point. Commonly used ones include red, blue, green and black. The electric eye positioning function is very common when the printed hose packaging is fake. It is used to position the sealing machine when the hose is automatically filled after the product is made. After the filling is completed, the hose is placed on the Automatic tail sealing machine, the machine senses the relevant color points and starts to automatically seal the hose to ensure that the packaging is in the correct position when sealing, and has nothing to do with the ingredients of the product.
