Interpretation of the development status and trend

Interpretation of the development status and trend of self-adhesive label printing (II)

the development trend of label industry

the development of packaging industry provides great demand for label production, and more and more enterprises enter the label industry. In the self-adhesive label printing industry, there are signs of overheating. In fact, there are too many manufacturers involved in the self-adhesive printing industry, and their production and processing capacity is too large. Although the market space is large, it is only a potential space, which cannot be greatly expanded due to the constraints of various factors

judging from the market reaction, the increase in label usage is obvious. By 2006, the global label consumption increased by 6. 2%, which will increase to 33 billion M2 compared with 2.04 billion m2 in 2OO1. The label market under development will grow at a double-digit rate. The growth rate of the developed market is 3 ~ 5%, but the growth rate is uneven. Among them, China has an annual growth rate of 15%, Eastern Europe has an annual growth rate of 12%, Latin America has an annual growth rate of 10%, and Europe and Japan have a growth rate of 3% - 5%

since low-quality labels cannot meet the decoration needs of containers such as plastic bottles, film labels will grow rapidly in the past 10 years; The paper labels used on bottles and cans will gradually decrease, and the labels in the mold will increase moderately; The application of light-weight glass bottles continues to increase the amount of shrink film labels; The consumption of PET bottle plastic labels will increase rapidly; The value-added and applicability of self-adhesive labels for glass and plastic containers will be further expanded; The rapid increase of printing equipment for variable information (such as text, bar code, data, batch, price and weight, etc.) will promote the development of variable residence labels; RFID (radio frequency identification) tags will grow at a rate of 10 ~ 12% per year

on the other hand, the domestic label market shows a polarized development trend. The products processed by the United States and Japan in China have high requirements for labels, and some require UL certification in the United States, which puts forward higher requirements for high-end labels. Some international famous brands such as P & G have higher requirements for labels. In China, some well-known brands even require more labels than Taiwan and Japan. While ordinary labels are low-grade and cheap. Wenzhou Cangnan and Longgang are the production bases of such labels, and their products are concentrated in paper labels, electronic labels, advertising printing labels, etc. Some labels, such as beer labels, have a large demand for beer labels in summer because of their large sales, which also drives the development of low-end labels

in general, the domestic label printing industry is gradually maturing, and label printing products are changing from medium and low-grade to medium and high-grade. With the development of market economy, the improvement of printing level and product quality, and the continuous expansion of application fields, China's self-adhesive label printing has a huge market development space. The domestic self-adhesive label printing market will maintain a rapid growth momentum for a long time

technical viewpoint

the label market shows diversity with the needs of consumers. The increasingly fierce industry competition has prompted the label industry to continuously add new technologies, such as radio frequency identification (RFID) for flexible packaging labels. From the development trend of global labels in recent years, we can see that digital labels and RFID labels have become new highlights in the industry, and they are also the development trend of pursuing security. At present, people's pursuit of convenience and efficiency makes the development of labels show a diversified trend. The existence of a variety of label types, each has its own advantages and needs, and it is impossible to replace each other. Which is better or worse remains to be discussed

full contact of label types

1. Shrink labels

in the field of labels, shrink labels occupy an important position and are often used to promote new products, including beverages, dairy products, powdered food and fast food. It is mainly used for shrink sleeve, full seal label, bottle cap and cap sealing, anti-theft tape and cluster packaging, etc. The shrink label has the characteristics of good gloss and good fit, which can redefine the beverage brand when used. Its gloss and shrinkage can make the packaging pattern on bottled drinks more vivid. By using shrinkage film, packaging bottles with novel shapes can be designed, and eye-catching colors can be used to realize 360 label design, highlighting the image on supermarket shelves

the demand for shrink labels is growing at an annual rate of about 20%

at present, PVC shrink film is mainly used for shrink labels. From the perspective of environmental protection, it is urgent to develop shrink film based on OPS and PETG as a substitute for PVC. Due to its light specific gravity, high shrinkage and excellent printing performance, OPS is widely used in the labeling and full sealing of polyester bottled soft drinks and the shrink packaging of optical discs. It has two-level limit protection of program control and machinery; PETG shrink labels can be used for label covers of daily necessities, edible oil packaging containers and other industrial shrink packages

due to the gradual prohibition of PVC labels in Japan, South Korea, Taiwan and European countries, environmental friendly shrink labels will be greatly developed in recent years. As new biaxial tensile films, OPS and PETG shrink films are basically blank in China at present, and their development and application have broad market prospects

2. In mold label

in mold label has been popular in Europe and the United States for many years because of its beautiful appearance, good anti-counterfeiting effect, recyclable environmental protection, and low mass production price compared with ordinary labels, and has entered a stable development period in nylon 6 reinforced 30% glass fiber. In the domestic label market, as an innovative labeling method, in mold labels have attracted the attention of many enterprises, and a small number of end users in China have begun to use in mold labels. However, due to the development of in mold labels, they are widely used in metrology and quality inspection compared with tensile testing machines; Rubber plastic; Metallurgical steel; Machinery manufacturing; Electronic appliances; Automobile production; Textile chemical fiber; Wires and cables; Packaging materials and food; Instruments and Apparatuses; medical apparatus and instruments; Civil nuclear energy; Civil aviation; Colleges and universities; Institute of scientific research and experiment; Commodity inspection, arbitration and technical supervision departments; Building materials ceramics; Petrochemical industry; There are a wide range of other industries, including raw material suppliers, hard packaging equipment suppliers, hard packaging production enterprises, label printing enterprises, end users and the whole industrial chain. Only the whole production chain has a certain foundation can it develop rapidly. Therefore, it is still in the late stage of wait-and-see in China, but its development is inevitable. After about five years of market cultivation, it will become a rapidly developing industry

the emergence of in mold labels is the result of the development and progress of materials, printing, ink and other technologies. In mold labels first appeared in China more than two years ago. With the development of labeling technology and the decline of label material prices, in mold labels have developed to a certain extent in recent years

in mold labels are made of plastic or paper coated with special hot-melt adhesives and can be used in blow molding, injection molding and thermoforming processes. The manufacturing process is: the manipulator sucks up the printed in mold label, places it in the mold, and melts the hot melt adhesive on the back of the in mold label with the help of the high temperature when the plastic melt adhesive melts, so as to integrate the in mold label and the container. The biggest difference between the in mold label and the traditional label is the different labeling method. The in mold label is not labeled after the plastic container is fully formed, but completed at one time with the container. As a new type of label, in mold label has many advantages

3. Novel appearance

in mold labels are mainly used in cosmetics, daily chemical products, pharmaceutical industry and lubricating oil industry. Because the label in the mold is naturally integrated with the bottle body, and deforms with the deformation of the bottle body, there will be no blistering, wrinkling and other phenomena. In addition, in mold labels use film and paper materials abroad, and film materials are mostly used in China. The film surface does not absorb ink, so the label has bright color, strong three-dimensional sense, and the color effect is significantly better than paper materials, and it can perfectly reflect exquisite patterns and small words. Relevant experts use a very vivid metaphor to illustrate this problem: the label in the mold is like embedding a painting in the wall, so that the painting and the wall become a whole, achieving the effect of natural harmony

4. Potential cost reduction space

at present, the price of in mold labels is twice that of self-adhesive labels, which greatly hinders the promotion of in mold labels. There are three reasons why it is expensive. First, monopoly. This technology has not been popularized in China at present. Only a few enterprises master the technology of in mold label, and monopoly causes high prices; Second, the manufacturing process is relatively complex and the technical content is high; Third, the loss is relatively large. If you use ordinary sheet fed offset printing machine or flexographic printing machine, it may cause a high scrap rate. It is better to use a special label machine

5, anti-counterfeiting function

the anti-counterfeiting function of in mold label is one of the important reasons why many manufacturers choose it. Self adhesive label technology has been developed very mature in China, so it is quite easy to copy. The in mold label is produced together with the bottle body, and it can only be counterfeited unless it is copied together with the bottle body. This technology is mastered by only a few enterprises in China, and the use of in mold labels requires special molds, and the production cost of molds is higher. A set of molds costs hundreds of thousands of yuan, which increases the difficulty and cost of counterfeiting. Therefore, the anti-counterfeiting function is most favored by customers. At present, in mold labels have many customers in China, such as Piao Rou, unified lubricants, Wang Zhihe seasoning series, Xi'an kaimi washing products, etc., which are largely aimed at its anti-counterfeiting function. At present, the end users of in mold labels are concentrated in the lubricant, cosmetics, daily chemical and pharmaceutical industries. The environmental protection of in mold labels is the reason favored by many manufacturers, because the in mold labels are integrated with the bottle body, the chemical composition is also the same, and the recycling rate is very high; In addition, the anti-counterfeiting of in mold labels is also an important reason for manufacturers' investment. The cost of label molds is relatively high (hundreds of thousands of yuan per set of molds), which virtually increases the difficulty of factory counterfeiting. Therefore, many domestic customers choose it to increase the anti-counterfeiting function

6. RFID tag

rfid tag is developed on the basis of electronic technology. It stores a huge amount of information, has flexible and fast non-contact reading and writing, and has strong environmental adaptability. According to the analysis and prediction of FS company on the global RFID tag application market, the global RFID market will soar from US $2billion in 2003 to US $10billion by 2009

the application field of RFID tags continues to expand and quickly infiltrates into various fields. The experiments and practical applications of RFID tags in logistics storage, manufacturing, commercial retail, commodity anti-counterfeiting, transportation, national defense and military and other fields are gradually unfolding. For example, Wal Mart, a global retailer, requires its suppliers to affix RFID tags to their products

China started late in this regard, and the RFID tag market is still in its infancy. There is a considerable gap between China and the world in the application of RFID. For example, the frequency of RFID tags
