To understand what quality the product is in the tube, some consumers look at the color of a small square on the tube spike. There is an opinion that the color of this object indicates the composition of the toothpaste. To understand what the strip on the tube means, you should familiarize yourself with the facts and theories.
Theory of the relationship between labeling and the chemical composition of the paste
One of the most famous theories that exists today is the theory of the relationship of the strip on the tube of paste and its chemical composition.
This statement reveals the meaning of color marking. A black mark at the bottom of the package means (according to the theory presented) that inside it is a mixture of chemical, harmful elements. This paste does not contain any natural ingredients. A blue bar indicates that the hygiene product contains 20% natural ingredients. The remaining elements of the composition are classified as chemical and, accordingly, harmful.
There are other colors of the stripes on the tubes. What do the red squares on the spike mean? Adherents of this theory are ready to reveal the secret. The paste inside such a package, in their opinion, has in its composition half of the natural components.
The highest quality oral hygiene product has a green strip on the tube. According to the theory presented, the product contains only natural components.
Theory of labeling versus use
There is a hypothesis that relates labeling to the duration of use of this product. What does the strip on the tube mean? This theory presents 4 possible answers.
Adherents of this theory believe that a paste with a blue mark on the commissure is suitable for daily hygienic brushing. Marking in red means that the contents provide a healing effect. But the use of such a product is allowed no longer than seven days.
According to the theory, paste with a green label on the package has a strengthening property. She is allowed to brush her teeth for exactly 30 days.
A black strip on the tube informs about the whitening type of paste, which adversely affects tooth enamel.
Theory of Consumer Income
Some theorists insist that the value of the strip on the tubes is explained by the financial situation of consumers who purchase this type of product. According to the hypothesis presented, a black strip is applied to the tubes of an economy-class product. This is explained by the fact that the composition of the content includes the cheapest components.
The strip on the tube of blue paste indicates the better ingredients of the product. Elite means are indicated by red markings. Also, such a tool, according to the theory presented, has the most sparing composition for tooth enamel and can be used daily.
The hypothesis is silent about the meaning of the stripes on the green tubes.
Theory of toothpaste causing periodontal disease
The multi-colored stripes on the tubes are explained by many assumptions of marketers, consumers and even some dentists.
This assumption from its position explains the strips on the tubes. What do these labels mean? Adherents of the theory explain the following. The black bar exposes the product that causes periodontal disease. In the market for oral care products, these pastes are the majority. What can not but scare.
A red mark indicates the presence of synthetic substances permitted by GOST.
But the green box on the edge of the tube indicates that such a product is the most environmentally friendly. According to theorists who consider this theory correct, this type of paste is most useful for human health.
Abrasive Theory
Colored stripes on the tubes, according to this assumption, indicate the frequency of use of the product due to the presence of abrasive components in their composition. Small particles, whitening and polishing teeth, spoil the enamel over time. According to the hypothesis put forward, products with the highest abrasive particles are marked with dark colors (blue, black, brown, etc.). Such funds can be used no more than once every 7 days.
Paste with a strip of red can be used up to 3 times a week, as they have less abrasive. It is permissible to brush your teeth daily with green stripe on the packaging.
Theories on the territorial purpose and content of petroleum products in the paste
Among the many assumptions and guesses about what the strip on the tube means, we should also note the hypothesis that the color of the label depends on the territorial purpose of the product. According to the presented statement, the black bar indicates the production of pasta for the countries of Asia, as well as the third world.
For Europeans, they make pasta with green or red squares on the packaging. But for the US, manufacturers mark the packaging of hygiene products in blue.
Another “geopolitical” theory is the oil version. According to her, a black bar on the tube indicates the presence of a large number of oil products. In a package with a blue strip, there are fewer such components. Almost they can not be found in the paste marked red. Green indicates an environmentally friendly product.
Theory of Dyes and the Conspiracy of Marketers
There is an assumption about the dependence of labeling on the presence of dyes in the composition of the product. A green strip on the tube is assigned to a paste of natural ingredients that do not contain synthetic dyes. But in a package marked with dark shades there are many harmful chemicals that give color to the paste. According to the hypothesis presented, such markings may be black, brown or blue.
There are also suggestions that packaging was not marked by a green stripe for a reason. Marketers, knowing that such a color correlates with nature and the benefits for humans, began to mark toothpaste with them. A tube with a green label should contribute to greater product sales.
Printing process
Whatever theories are put forward, the fact about the technology of the production process cannot be overlooked. According to it, a color mark is needed in the production process to indicate the place of packaging trimming. The high-tech optical device reads the optical marker and seals the tube.
The mark is made in the same color as the barcode. Sometimes it is performed in accordance with the packaging design. The darker the color of the markings, the more contrast it looks on a white background. This allows the machine not to miss in the process.
Packing and dyes
To understand what the stripes on the tubes mean, you should also familiarize yourself with the packaging design principle. There are 4 primary colors used when printing on equipment. They cannot always fulfill design ideas. Therefore, there is a prepress technology. Extra shades are removed, they are replaced by mixed ones. Color division occurs in accordance with the number of sections of the printing equipment.
Having assigned the primary color at the preparation stage, the printing feature of the barcode and readable elements is taken into account. They cannot be created by superimposing two colors. Otherwise, with a slight offset, the text and marks become unreadable. Therefore, one more is added to the main four - the main shade. The mark at the end of the tube, and the barcode, and the font on the package will be just such an additional color .
This helps optimize producer costs. And the equipment is much easier to catch one color of all elements. The very meaning of the technology of applying the design elements and information on the packaging by the printing method is to correlate the color of the tag with the primary color of the print. Its selection should be contrasting. And the best contrast is a white background with black or blue elements.
When wondering what a strip on a tube means, you should not listen to assumptions and hypotheses passed from mouth to mouth of people who are far from the production technology of such a product as toothpaste. Theories among consumers, marketers, and even dentists are, in fact, far from the truth. The facts provided by the technology of production and printing on the packaging of the product indicate a completely different sense of the label in question. Everything is very simple. The marking on the soldering of the tube is just a part of the technological process, which depends on the main color of the package design.
