Some say that the color bar at the bottom of the skin care tube represents different ingredients. Green means all natural.Blue represents part natural, part medicinal;Red means half natural, half chemical;Black 5% chemical, 95% natural base, this is a false statement, color is often used for positioning purposes only.
The positioning function of the electric eye is used in the printing of hose packaging. It is used for the positioning sense of the end sealing machine when the hose is automatically filled after the product is made.After filling, the hose is placed in the automatic 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 the tail, which has nothing to do with the composition of the product.
