Mainly used for decorative decals on cars and motorcycles, logo text on trademark windows, reflective films on highways, markings on containers, etc.

According to the scope of application, it is divided into basic tags and variable information tags. Self-adhesive labels are now widely used in the daily chemical industry. It is understood that at present, the proportion of domestic daily chemical products using self-adhesive labels as labels exceeds 30%, and according to statistics, the current self-adhesive labels on the domestic market are still maintaining a rapid growth momentum in the daily chemical industry, and are getting more With a wide range of applications, label materials will also develop in a high-level and diversified direction.

Daily chemical products have high added value, so there are many brands and competition is fierce. When consumers choose a product from a dazzling array of products, the outer packaging of the product is the key factor to attract consumers, and the most important thing in the outer packaging of daily chemical products is the label. It can be seen that the exquisiteness of the label plays a key role. Self-adhesive labels can perfectly reflect the requirements required for labels. The characteristics of self-adhesive labels meet the application conditions in the anti-counterfeiting industry. The earliest anti-counterfeiting labels in China appeared in the mid-1980s, and their application fields include alcohol, food, medicine, health products, cosmetics, children's products, toys, clothing tags, shoe labels, computer software and hardware products, sporting goods, auto parts, Agricultural supplies, etc. The use of self-adhesive anti-counterfeiting labels on goods has broad market development space in China.

In short, the application characteristics of self-adhesive labels can be used to regard self-adhesive labels as carriers of anti-counterfeiting information. In this way, their application scope will be wider, and labels with personalized information will have broad prospects. In particular, some current policies and regulations issued by the country (such as requiring imported products to bear Chinese descriptions, origin markings, etc.) have provided market space for the application of self-adhesive adhesives, and also provided business opportunities for self-adhesive printing.

The General Administration of Quality Supervision, Inspection and Quarantine stipulates that meat products, dairy products, beverages, condiments, frozen foods, instant noodles, biscuits, cans, quick-frozen rice noodles, puffed foods and other foods have begun to implement market access systems and must be Only after the QS mark is affixed can it leave the factory and enter the circulation field. In addition, the General Administration of Quality Supervision, Inspection and Quarantine also stipulated that from August 1 this year, 132 types of commodities in 19 categories across the country (involving electronics, home appliances, air conditioners and other products) must implement compulsory certification (i.e. 3C certification), stipulating that 6 types of Specifications of self-adhesive labels, any products without the 3C compulsory certification mark are not allowed to leave the factory, nor are they allowed to enter the circulation field for sale. This regulation also provides business opportunities and markets for self-adhesive companies.

Self-adhesive labels are very popular in this field, not only because they can be attached, printed, and designed, but more importantly, electronic products need to use labels to achieve certain effects. For example, the label has a strong texture and can work well with electrical appliances, or the label can resist corrosion and high temperature in the external environment. Several forms of label materials are often used in different parts of an electrical product. The huge development of the electronics industry, especially in South China and East China, has a relatively large proportion of exports, which has also driven the consumption of self-adhesive label materials. main areas. Like other fields, label materials used in the electronics industry generally have relatively high requirements. Many multinational companies have their own strict testing methods, such as measuring viscosity, scratch resistance, temperature resistance, etc. But generally speaking, many companies have put forward requirements for label materials to have UL certification.

At present, equipment that combines glue, soft, concave, convex, and screen printing has pushed traditional label and trademark products to new heights; while digital systems have opened up a new market for labels and trademarks. At present, the key to the further development of the domestic self-adhesive label printing market is not whether the industry copies the mainstream "flexo printing" in Europe and the United States, or imitates the mainstream "relief printing" in Japan, but how to combine national conditions and the product itself. nature. Characteristics to select or combine a cost-effective printing process route and corresponding equipment system. Because, under certain conditions, the quality of self-adhesive labels printed with various modern printing technologies is almost indistinguishable. The difference lies in the adaptability of the process route and the return on input and output.

Issues that need to be paid attention to when printing self-adhesive labels:

Small self-adhesive labels are often an important reflection of the company's image and brand. They play an important role in reflecting product quality and arousing consumers' desire to buy. effect. Then choose a label, or a self-adhesive label

How to avoid glue back shadow during the self-adhesive label printing process. For cylindrical bottles, especially those with a diameter less than 30MM, materials must be selected carefully. If the label size is too large or too small, care should be taken to conduct a practical test. If the object to be attached has an irregular surface or even a spherical surface, there are specific considerations for the type of label material, thickness and adhesive. Some rough surfaces such as corrugated boxes will affect labeling, and the varnish on the surface of corrugated boxes will also have an impact. Automatic labeling machine labels, labeling tests can be performed if necessary. Even if the label is affixed at room temperature, attention should be paid to whether it experiences high temperatures during export transportation and use. A watery or oily environment will affect the characteristics of the adhesive. Pay attention to the environment and temperature of labeling. Plasticizer sometimes oozes out from the surface of soft PVC, so special attention should be paid to selecting the appropriate adhesive. ⒈Anti-counterfeiting label screen printing anti-counterfeiting mainly refers to anti-counterfeiting for the coating part and part.

⒉ It is recommended that the coating part should not be laminated as much as possible, because the cost of lamination is high and it is difficult to cut and polish. Glazing oil is the best way.

⒊When making self-adhesive labels, try not to apply varnish on the whole, just apply it on part.

⒋The thickness of the screen printing mesh affects the thickness of the coating, and the thickness of the diluent affects the appearance of the coating.

⒌The screen printing anti-counterfeiting technology of self-adhesive labels uses water-based stencils for water-drip anti-counterfeiting, while others generally use oil-based stencils.

⒍The mesh number of the screen printing screen used is generally 250-350 mesh. Theoretically, the larger the mesh number of the screen printing screen, the stronger the effect and the thicker the coating.

⒎In actual use, we found that the thicker the ink, the more detailed the silk screen pattern will be. If the ink is not diluted enough, it may also become crusty.

8． Silk screen printing is related to typesetting and design. The larger the typesetting space, the better the position adjustment during screen printing. Silk screen printing is also related to the weather. Too humid or too high temperature will affect the effect of silk printing. Generally, when the temperature is high, slow drying water or extra slow 783 should be added, and when the temperature is low, the drying water should be accelerated.

9． Silk screen printing should pay attention to the customer's individual mark requirements and coding. It does not matter if the coating is thinner if the printing on the coating is thin; if there is no printing on the coating, the coating should be thicker; the other is the font when coding. Make the strokes as clear as possible but as thin as possible.

10． Silk screen printing is related to the order in which labels are placed: Pay attention to distinguish between those with serial numbers and those without serial numbers.

11. When printing, you should pay attention to the material. Different materials have different inks and methods.

12． When screen printing, you should pay attention to whether lamination is required for subsequent processing. If the screen printing part is easy to fall off or be erased, lamination is required.

13. When printing, you should pay attention to whether you need to register colors. Generally, offset printing with color registration is better, but often silk printing can be printed that offset printing cannot print. Therefore, it is often said that silk screen printing is omnipotent.

14. The screen printing technology of self-adhesive labels requires an understanding of the performance of the ink, as well as the screen, position, plate adjustment, plate repair, and plate washing.

15. When printing silk screen, pay attention to the surface not to be smeared or blistered;

16. It is worth reminding that when doing drip anti-counterfeiting, it is generally recommended to do it all at once, because this kind of screen often has a slight pause in the middle and may not be used.

17. Silk screen printing should be made according to the production order. If the temperature change is anti-counterfeiting, you should pay attention to whether the temperature change disappears or changes in color. Pay attention to whether the temperature change effect is reversible or irreversible.

18. The standard for measuring the performance of silver powder used on the screen printing surface is: it can be scratched with fingernails but cannot be wiped off with fingertips.
