What do those colored bars at the bottom of skin care products mean, black, blue, white and green?

The red, blue, green and black color bars at the bottom of skin care products are electric eye positioning points, which are used to locate and identify the products when they are closed in the production process of skin care products.

green represents pure nature, blue represents natural and medicinal ingredients, black represents pure chemical ingredients, and white represents semi-natural ingredients.

the electric eye positioning function is used in printed hose packaging, and it is used for the positioning sense of the sealing machine after the product is manufactured and the hose is automatically filled. After the filling is completed, the hose is placed in the automatic sealing machine, and the machine senses the relevant color points and starts to automatically seal the hose, so as to ensure that the packaging is in the correct position when the hose is sealed, which has nothing to do with the composition of the product.
