First, the choice of self-adhesive printing raw materials When selecting raw materials, we must choose high-quality self-adhesive materials with qualified physical and chemical indexes, rather than products with expired or unstable physical and chemical indexes. Although the latter price is low, but due to the unstable quality of such materials, large consumption in each process, and even lead to the normal processing of equipment, waste of raw materials at the same time also waste a lot of manpower and material resources, the processing cost of the finished product label is not necessarily low, more serious is that there may be customer returns, and even lose customers. The selection of raw materials should be considered from the following two aspects 1.Self-adhesive printing and self-adhesive printing processing characteristics ①The surface gloss and color consistency of the self-adhesive printing surface material and the uniformity of the density determine the uniformity of the ink absorption of the self-adhesive material, and also determine the color difference of the same batch of label printing. The coating strength of the surface material determines whether a large amount of paper powder will be produced when printing, and is also an important indicator to determine the quality of printing. ②The thickness uniformity and strength indication of self-adhesive printing base paper and surface material These indicators are not only related to printing performance, but also an important indicator to determine the uniformity of die cutting and the speed of waste discharge and paper edge breakage. If these indicators are too low, the label machine can not be produced at high speed ③ Flatness or uniformity of rewinding tension of self-adhesive printing materials Whether it is single sheet printing or web printing, the flatness of the material determines whether the printing can be correctly fed, run and register, and receive paper. For the reel material, the rewinding tension will play an important role in the flatness of the end face of the reel material, whether there is infiltration and whether it can be correctly registered. ④ The uniformity and correct coating amount of self-adhesive printing adhesive and silicone oil coating These indicators directly affect the stripping force (release force) between the label and the bottom paper, and the size of the stripping force directly affects the die cutting waste and the speed of the machine, and the stripping force also determines the label marking condition, that is, the application situation. In addition, the size of the amount of glue will also affect the cementing condition of the end surface of the material. Therefore, the purchase of self-adhesive materials should be carefully tested, and those materials with the appropriate amount of glue and silicon coating should be selected.

Non-stick coating refers to the coating formed after coating with low surface energy, easy to clean and other characteristics of the coating, which is widely used in all kinds of food contact, hardware products, mechanical parts, chemical equipment, electrical equipment. Non-stick pans are also the most widely recognized non-stick paint application scenarios. 1, non-stick coating has fluorine resin system, silicone system, ceramic system three mainstream products. At present, the non-stick coatings on the market are mainly divided into fluorine resin non-stick coatings, silicone non-stick coatings and ceramic non-stick coatings, among which fluorine resin non-stick coatings are the mainstream, fluorine resin non-stick coatings can be divided into polyimide binders and polyaryl ether binders according to the differences in binders. In the future, polyaryl ether binders will be the direction of technological evolution. According to the type of solvent, it is divided into water-based non-stick coating, oily non-stick coating, powder non-stick coating, and water-based non-stick coating is the mainstream at present. 2, fluorine resin non-stick coating: performance "unique", generally need special engineering plastics as adhesive use. Fluorine resin non-stick coating is usually PTFE based PTFE, PFA, FEP three mixture of the form exists, binder to polyimide, polyaryl ether two types of special resin based, coating performance to composite multi-coating is best, fluorine resin non-stick coating has the best non-stick and comprehensive protection effect, in addition to the field of kitchenware and home appliances has a better application, Fluorine resin non-stick coatings can also be widely used in harsh acid, alkali, salt, high temperature protection, lubrication requirements, such as chemical reactors, large industrial nuts and bolts. However, due to the high melting point of fluorine resin and adhesive resin, the coating film baking temperature is high and the energy consumption is large, the adhesive resin is difficult to water-based processing and high energy consumption, and it is difficult to avoid the use of high temperature solvent when baking film, which limits the further improvement of fluorine resin non-stick coating in environmental protection. Fluorine resin PTFE, PFA, FEP are perfluoroppolymer, molecular chain structure due to C-F bond, its bond energy of 485kJ/mol, in all chemical bonds can be called the first, long-term use temperature 220℃, almost with all substances are not bonded, with excellent chemical stability, heat resistance, acid and alkali resistance, flame retardant, aging resistance and self-lubrication. Applied to non-stick coatings, in the range of cooking oil smoke temperature 180℃, fluorine resin structure is stable, safe and reliable, its low surface energy properties can effectively prevent food oil, protein and other materials adhesion and penetration, so it becomes the ideal choice for manufacturing non-stick coating...

Color printing packaging is light in weight, easy to carry, and the source of raw materials is wide, and it is widely used in food, traditional Chinese medicine, daily necessities and other industries. Do you know what are the common production processes of packaging? First, the film Laminating process is a kind of surface processing process, after printing is completed, this process is also called "plastic", "laminating", "laminating", through hot pressing on the surface of paper products with a layer of transparent plastic film, so that the surface of the printed matter more shiny, on the other hand, the printed matter also played a protective role, this is laminating, at present, The film coating process is often used for book covers, picture albums, postcards and maps. Two, hot stamping Hot stamping is to first make the pattern or text that needs to be hot stamped into a convex plate, and with the help of hot pressing method, a variety of aluminum foil sheets are printed on the substrate, showing a strong metallic light, so that the product has a good texture. It is often used for decoration of household appliances and electronic products. Three, die cutting indentation Die-cutting indentation is a process of post-printing processing, which will no longer limit the edge shape to right angles according to its own desired graphic specifications. The indentation process is to use a wire cutter or a wire die to press out line marks on the sheet material through the action of pressure, or use a rolling wheel to roll out line marks on the sheet material, so that the sheet material can be bent and formed according to a predetermined position. With the improvement of people's exquisite degree of product printing and environmental protection requirements, there are more and more production methods of printing and packaging, as long as one of the above processes is mastered, it will be able to better speed up the production process.
