Which one is best to have blue, black, or green at the end of the toothpaste?

The color bar at the bottom of the toothpaste is used for positioning and identification of the product in the production process of toothpaste, also known as the electric eye positioning point, commonly used red, blue, green and black, etc., the function is to ensure that the printing layout is centered during the closure, and there is no special significance.

Toothpaste is produced into a roll of material, the whole roll of material needs to be processed into a single piece of hose, the latest processing equipment is fully automatic cutting, in the cutting process, the machine equipment is relying on the automatic tracking of the electric eye, every time a cursor is tracked, it will be automatically cut, the existing equipment cuts 120 200 tubes per minute, if there is no cursor, the machine will be cut without standard, resulting in the problem of different lengths (this cursor will be cut off after the toothpaste body is sealed, and some will be left in a part).

The so-called color bar at the bottom of the toothpaste tube represents the different ingredients, and the green color indicates all-natural; Blue indicates a part of natural and part of a medicinal ingredient; Red indicates half natural ingredients and half chemical ingredients; Black means it's all chemical and it's a rumor.

The tail of the toothpaste has blue, black and green, of which green represents pure natural, blue represents natural + medicine, and red represents natural plus chemical ingredients. Therefore, when choosing a toothpaste, you should try to choose a toothpaste with a green mark, which means that the toothpaste ingredients are from pure natural sources and have a better protective effect on teeth and oral health.

Truth: The color bar at the bottom of the toothpaste tube is commonly known as the electric eye positioning point, which is used when the hose is automatically filled after the product is made and the positioning induction of the tail sealing machine is used. After the toothpaste hose is filled with toothpaste, the hose is placed on the automatic tail sealing machine, and the machine will automatically seal the hose after sensing the relevant color points to ensure that the packaging is in the correct position during the tail sealing, and has nothing to do with the composition of the product.

Tips: There is no classification of toothpaste such as pure natural and pure chemistry, and the raw materials used can be used as long as they meet the "Specification for Raw Materials for Toothpaste".

On the official website of the China Oral Cleaning and Care Products Industry Association, you can find a "description of the background color code of toothpaste tubes". It is pointed out in the "Instructions" that the color code at the bottom of the toothpaste hose is mainly used for positioning and identification when filling and sealing the toothpaste, which is called the electric eye positioning point in the industry. Electric eye positioning points are very common in hose packaging, and are widely used in hose packaging products, such as cosmetics, food, etc.

It is used for the positioning sensing of the tail sealing machine after the product is automatically filled to ensure that the package is in the correct position when the tail is sealed. The color of the color code at the end of the toothpaste hose depends on the packaging design of the toothpaste hose, and the color that is already available on the hose, which is clearly different from the base color and easy to be sensed by the device, is generally selected, and has nothing to do with the composition of the product. Toothpaste is made up of a variety of ingredients, and consumers can learn about the specific added ingredients of toothpaste through the ingredient list on the toothpaste package.

The meaning of the green-blue-black bar in toothpaste.

The blue, black and green at the end of the toothpaste are the positioning identification marks when the machine seals, which is called the electric eye positioning point, which is used to ensure that the printing layout is centered during the sealing and is used for the positioning sensing of the sealing machine, so as to automatically seal the tail.

Don't blindly believe in the efficacy, the toothpaste does not stay in the mouth for a long time when brushing your teeth, and its effect is difficult to exert in a short period of time.
