Trend of Chinese flexographic printing technology vector paper cup

2017/11/15

Times are developing and society is progressing. With the development of social information and economic globalization, printing is also undergoing tremendous changes. In the "flat, convex, concave, soft," the four major printing processes, derived from the flexographic printing flexo, after decades of twists and turns, finally dawn, flexo market from small to large, from weak to strong The trend has caused widespread concern in the market. --- Vector paper cups

According to Japan's "Printing Information" magazine statistics: the 20th century, the late 90s, global flexo printing every year at an alarming rate of 70% growth, flexo printing in 2000 accounted for 18 to 19% of the global printing market. Experts predict that by 2005, Flexo is expected to rank second in the "Big Four" print layout. However, at the same time, the growth of global gravure was flat, while offset printing showed a slight decline. So why flexo from the "flexographic printing" ugly duckling transformed into a beautiful "white swan"? The main reason for the analysis is that in recent years, flexo has been greatly improved due to the application of a large number of new technologies such as ceramic anilox rollers, sleeve rollers, water-based ink, UV ink, laser engraving technology and computer technology Its printing quality, coupled with the environmental advantages of water-based inks in Europe and the United States market has been a huge development.

Development Status of Flexographic Printing Technology in China

China in the mid-1990s there have been introduced flexo equipment heat, forming a strong "flexo wind." By the end of 2003, more than 270 flexo printing equipment had been introduced nationwide, of which 90% were narrow-format unit flexo machines and stacked flexo machines, and about 10% of wide-band satellite flexo machines. It is estimated that the introduction of domestic flexo machines is increasing by about 30 units per year. At present, there are about 350 flexo printing production lines in China, of which about 80 are narrow flexo printing production lines independently developed and produced in China about.

In 2001, Shandong Quanlin Paper Co., Ltd. introduced a world-leading technology of shaftless transmission, width 1300mm, 8-color high-speed satellite flexographic printing production line and cross-cutting machine and related equipment from German F & K Company. The machine speed is basically stable at 200m / min, more than double the speed of the domestic unit flexo machine. Printed solid color field consistent, network clear, high precision overprinting, quality upper. Now mainly used in milk, fruit juice carton packaging and high-grade packaging printing.

2002 Shanghai International Paper Co., Ltd. from Germany BHS printing machinery company introduced two 8-color, 820mm width satellite flexo production line, speed 250mm / min. Now three classes of production, for the larger dairy enterprises such as "Mengniu", "Yili", "Bright" roofs and other beverages, fruit juice to provide packaging products.

In addition, in 2003 Guangxi Guilin Aoqun Co., Ltd., Shenzhen Jinjia Color Printing Co., Ltd. and Lanzhou New Century Color Packaging and Printing Co., Ltd. and other units in order to meet the environmental protection, new security, new printing materials and other tobacco, medicine, cosmetics packaging, ticket printing Need to have introduced a number of Czechoslovakia EM410 8-color, 9-color, and 10-color flexo machines.

Due to the rapid development of flexographic printing technology in our country, the development and production of domestically produced flexographic printing machines, anilox rollers, plate materials, printing inks and plate making technologies are strongly promoted. There have been more than 10 manufacturers (such as Xi'an Black Cattle, Shaanxi printing, Beiren Fuji, Shanghai Purple, Qingzhou Italian high of God, Wenzhou, etc.) successfully developed a wide range of specifications, narrow-format unit flexo machine. Zhejiang Ryan Machinery Factory also produced a laminated four-color trademark flexo machine. Domestic flexo printing quality can completely meet the requirements of packaging and printing, on the whole, the equivalent of imported products in the upper level. The domestic 8-color unit flexo machine general price is about more than 100 million yuan, while the same specifications of the imported equipment is required more than 500,000 US dollars, actually several times higher than the domestic equipment. Therefore, due to the improvement of processing and manufacturing of domestic flexo machines, coupled with the price advantage, Beiren Fuji and Qingzhou Yigao Fat Packaging Machinery Co., Ltd. have also exported to Japan and Vietnam.

The key component of flexo printing machine is anilox roller, Shanghai Institute of Printing Technology took the lead in the successful development of electronic engraving metal anilox roller. Then ceramic anilox roller, laser engraved rubber seamless roller, rubber seamless sleeve, also have come out. In the flexo plate making, due to the Dalian Foley Flexo Plate Co., Ltd., Shanghai Renshi plate today good company introduced a number of units such as the United States, the Netherlands and other foreign set of flexo plate making equipment, technology and technology software, so that domestic Flexible platemaking technology soon with the international level at the same level. In addition, the flexo ink used to start also need to import from abroad, and later Shanghai Institute of Printing Technology, Shaanxi New Century Institute of Printing Materials and other units co-operation, the successful development of the water-based ink, water-based Varnish, water-based additives and UV Inks, UV varnishes, UV auxiliaries, etc., make flexo a solid foundation for "green printing".

After nearly 10 years of production practice, flexo printing in China's packaging and printing market has initially formed a scale. Printing range, types continue to expand, flexo market share also gradually increased. However, compared with foreign advanced countries, we still have a long way to go. For example, North America, Europe and other packaging and printing markets more mature countries and regions, flexo market share has accounted for 70% of the packaging and printing market, while our situation is unsatisfactory, much lower than 10%, and most of them are medium and low-grade printing product.

At present, China's flexo printing has been fully able to meet the requirements of cigarette packs, pharmaceutical packaging, food packaging, trademark labels, stickers printing and other packaging and printing, and can be completed online printing glue, die-cutting and other processing can be enhanced Work efficiency, reduce costs, improve production efficiency. According to statistics, now the domestic flexo printing machine for cigarette packaging accounted for 30%; used for label printing accounted for 15%; used for adhesive printing accounted for 35%; other printing accounted for only 22%.

In addition, domestic production of cutlery, paper cups, beverage packaging, 80% are using flexographic printing. Food industry packaging paper and packaging printing, but also the gradual adoption of flexographic printing. For example, hamburger wrapping paper, McDonald's food packaging, Erie ice cream boxes and so on have adopted the flexo method. Long its is the current flexo application of the best, and the largest proportion of the corrugated box printing, annual sales of about 70% of flexible plate are in the carton industry. In addition, some international multinational companies in Shanghai and Beijing consider that "flexo printing is green printing" because they consider the use of water-based inks as flexo printing. Pollution of printed products is not harmful to health and environmental protection. The "green packaging" Will certainly greatly win the customer's approval, therefore, these brand-name products are used flexo packaging. Seen in this light, flexo printing in packaging and printing industry has shown its superiority, not only its wide range of carrier printing, and print quality has gradually and offset printing, gravure move closer, with broad application prospects.

Trend of Flexographic Printing Technology in China - Vector Paper Cup

China's packaging and printing industry has been the original offset printing, lead printing two hegemony situation, is gradually transition to offset printing, gravure, flexo three pillars of the pattern. And in the next few years, the market share of the three will be further balanced. Now its development trend is briefly summarized as follows:

1, Judging from the status quo and history of flexo printing in our country, great progress and development have indeed been made in the past ten years. On the one hand, the domestic flexo printing machine and its supporting equipment research and development work has been firmly rooted in the field of China's printing and manufacturing industry, is currently to the middle and high-end products to enter; the other hand, flexo printing in China's packaging and printing market The initial formation of the positioning phase, printing range, types continue to expand, flexo market share increased rapidly, flexo product quality improved significantly. Trademark labels, plastic flexible packaging, folding carton is the current flexo production in the packaging and printing market in the three "highlight." To be sure, printing high-precision products is definitely a trend of flexo printing in the future.

2, China's current introduction and self-developed flexo machine organic group, stacked and satellite three, crew and satellite are the two most important models. Compared with the unit type, satellite flexo machine has a higher overprint accuracy. Because the tape is tightly wrapped in the center of the impression cylinder, so the tension is very stable; In addition the machine structure is simple, good rigidity, short distance between the embossing points, but also easy to register control, the use of more stable performance. In the European and American markets, satellite flexo machines account for about 70% of the total flexo printing machine market, most of which are used in flexo printing, trademark labels and corrugated pre-printing. Satellite flexo machine technology in foreign countries is quite mature, but only in its infancy in China, but revealed a strong vitality. It can be expected that satellite flexographic printing presses will surely occupy a very important market in the field of packaging and printing as the domestic market pays more and more attention to the development of flexo printing technology as well as the perfect technology of flexo printing equipment, inks, plates and plates. Share. In the next few years, the satellite flexo printing machine will be our country flexo machine development and production of "top priority."

3, flexo plate making is also a very important issue, not only its plate making fees much higher than the offset, but also a headache is its printing durability is low. Especially as the medium and high-end products, the network cable version is even more prominent outlets easily expanded, paste the phenomenon of piling ink often occur, relative to 175 lines / inch or higher number of lines will not be able to achieve normal mass production. And reach the number of network lines close, medium and high-end products, fine, delicate degree is difficult to reflect. At present, there have been several domestic use of laser engraving flexible version of the new production process, this process on the number of high-speed network and durability have significantly improved. Therefore, many professionals predict: take too long, there will be a new breakthrough in flexo printing high-precision products, the use of laser engraving plate will be an inevitable trend.

4, shaftless drive technology is the world's most advanced printing press drive system, it is the use of electronic gear instead of the traditional mechanical gear, remove the drive shaft. That is, in each printing unit, AC vector variable frequency motor is used to drive independently, and the controller performs frequency conversion speed regulation to ensure the synchronous operation of each printing unit. At present, more than 50% of the advanced high-speed high-speed gravure presses in Europe adopt the shaftless transmission system. Only 30% of the high-end products in Japan representing Asian technology adopt the shaftless transmission system. The use of high-end shaftless gravure printing machine in China has just started. In 2003, Zhongshan Songde Packaging Machinery Co., Ltd. and Shaanxi Beiren Printing Machinery Co., Ltd. successively developed the shaftless high-speed gravure printing machine.

In addition, Valmet machining machinery entered the field of shaftless development of flexo two years ago and has developed several 8-color, non-shaft-driven Rotomec flexo machines. Today the company extends the development of a shaftless flexo machine to the 10-color field and successfully developed a new RotomecEG500-3 10-color shaftless flexo machine. Therefore, experts believe that: Shaftless drive technology is not only a trend of today's gravure printing machine, the same high-end flexo printing machine is also an inevitable trend of development.

In short, as China's flexo technology further develops in depth, we should sit down calmly and think about it: a careful analysis of past major experiences and lessons, and a clear understanding of the prosperity and prosperity behind Many defects and deficiencies (such as blindly introduced, equipment selection is not complete, resulting in waste; lack of flexo auxiliary materials, poor supply channels; technical training can not keep up, low level of worker operation, etc.), the experience of the car can "repeat the mistakes ". We have every reason to believe that with the concerted efforts of all our colleagues in the industry, we will actively explore the key points and overcome all the unfavorable factors. We will absorb and absorb new foreign technologies and technologies in a timely manner. Just around the corner, let us soon usher in the development of flexo printing another spring.
