Heat-shrink label is an element of a product,which is attached to the shell, and then cooled, which allows to take the shape of the surface. They are simply irreplaceable in those cases when the goods have a complex curved surface of the shell.
The label performs several useful functions,when they put it on. It significantly increases the strength of the packaging on which it is worn. In addition, the shrink label perfectly copes with the protection of goods from moisture, ultraviolet. Another important function of this element is the allocation of products from possible counterfeits. The original labels often have a variety of signs that confirm that the goods are original, not fake. Well, and, of course, it is worth saying that the appearance of the packaging on which such a wrap is applied has an excellent appearance that attracts the attention of potential customers.
Heat-shrink label is the best choice inif you want to cover the product with a curved surface, any bends, etc. It should be noted that applying this element can help to cope with such a problem as a defect in packaging. With the help of a label, you can easily close all unsuccessful places on the container.
The most common shrinkthe label has received in such an industry as the chemical. It is also very often used in the pharmaceutical and cosmetic industries. The reasons for which the label became the most successful, in these industries, is that it helps to distinguish between original products and counterfeit, and also helps to determine whether an unauthorized opening of the package was performed. Since the resistance of the label to moisture is quite high, it is used with great success in the manufacture of hygiene products. To such means it is possible to carry shampoos, balsams, etc.
Another important point of using thiscoating. Many large producers of aluminum cans have recently abandoned the costly printing operation for such containers. They prefer to apply a shrink label on a bottle, can or other container of aluminum, since it is cheaper, and the wrapper covers 100% of the shape of the package.
It is worth noting that to maintain highcompetitiveness, it is necessary to constantly improve your product, make it either cheaper, or tastier, etc. Changes affect both the appearance of the container and its composition. However, what remains unchanged is the label. More often than not, drastic changes can alienate the buyer. But the changes in the heat-shrinkable details of packaging design can be so original that they will give something new to the product, without making too many changes. In other words, the life of the label is very, very large.
The first important advantage thatapplying a shrink label is the ability to take a shape that is 100% consistent with the surface of the container. This quality makes it possible to use this element as the main package for storing several types of goods. It is also worth mentioning here that this part is characterized by great rigidity, which allows you to prevent any damage during transportation.
The second advantage lies in the waydrawing an image on the label. Shrink equipment, with which the process of application is carried out, displays the image on the inside of the film. This method allows you to greatly increase the duration of the image on the label. The outer layer of the film reliably protects the inner from all unfavorable environmental influences. Another of the advantages is the saving of the stored goods from direct exposure to ultraviolet rays.
What to pay special attention to?The main material is shrink PVC film. The thickness of the original raw material is from 35 to 70 microns. The production technology of this element is such that the application of images, letters and other things is carried out on the inside, which allows to leave the outer layer unchanged. Thanks to this method of application, it is possible to keep the appearance of the entire label in its original form for a fairly long period of time.
There are several ways of printing on the label.The most common are offset printing, gravure printing, and a combination of these two types. It is worth noting that if you use the second method of printing, it opens up such possibilities as applying thermoactive glue, the possibility of selective varnishing, as well as printing with different types of paints.
After the printing process is completed, it is takenA piece of roll material, from which a cylindrical sleeve is formed. After that, the shrink PVC-label, which has the form of a sleeve, is put on the container. And then, under the influence of pressure and temperature, tightly adheres to the container.
Here it is important to note that the application technologyThis element may differ depending on the performance requirements of the process. Also, the type of container and the material of the label will be strongly affected.
The simplest application technology is divided intoseveral stages. At the first stage, the roll material is taken, on which all the necessary images have already been printed, and cut into the required copies. Next is the process of placing the label on the container itself. The final stage of applying this element is shrinkage in a thermal tunnel.
It is worth adding that you can apply the label ason the packaged product, or on an empty container. The price of a shrink label on a bottle varies from 50 to 700 rubles per roll. It is very important. Labels are not sold for one, two, three pieces, and so on. Direct sales of rolls, the cost of which varies depending on the length.
To date, there are three most common types of labels.
The first type is a semi-hose label.The peculiarity of this variety lies in the fact that it allows to provide a modern and progressive form of capacity. This is the simplest type of this element, which allows you to improve the appearance of products in order to attract more attention to it.
The second type is label-sleeves.This type is considered to be more qualitative, as it is able to withstand mechanical loads, and also tolerates the negative impact that the environment can create. Plus, it's worth adding that this kind provides a long and high-quality image display, which is applied to the label.
The last kind is polyethylene shrinkfilms. This type is the easiest to determine, since they are most often transparent, which allows a good review of the content. However, this category of labels also well resists all negative influences.
The advantages of this type of packaging include the following:
Use the film can be on a variety ofmaterials - metal, glass, plastic, polyethylene. Most often this category of labels interests producers of alcoholic beverages, since the shape of the bottles is rather complicated - a narrow throat and a wide bottom.
In everyday life these films are almost always boughtfor egg wrapping for Easter. The network has a lot of reviews about this product, but if you combine them all into one, then all buyers consider the advantages that they are pretty beautiful, and putting them on is very simple. Out of the shortcomings, everything is highlighted by the fact that after the eggs dry out, removing this film from the shell is quite problematic.
