Tissue products open up a Xintiandi of flexographic printing

flexographic printing, as a printing method that meets the future environmental protection needs, has been more and more widely used in packaging in recent years, such as labels, folding cartons, flexible packaging, cartons and other fields. However, when it comes to the application of flexographic printing in tissue series products, it is still little known in China, mainly for two reasons: first, the domestic flexographic printing process started later than foreign countries, and there is still a big gap in market promotion and equipment use; The second is the difference of consumer culture. Tissue is a design theme with wide content and artistic interest in the West. Beautifully printed napkins can be used in different occasions, such as the fairy tale series launched on Christmas and children's day. At the same time, it is also a kind of affordable personalized advertising form, which is common in restaurants or hotels. With the increasingly personalized and fashionable development of people's lifestyle, personalized tissue has become a trend nowadays. For example, specially designed tissue products are often used on special anniversaries such as weddings, banquets or company annual meetings. Therefore, tissue printing has developed rapidly in the past few years

at present, the monochrome printing paper towels used by McDonald's and KFC are mainly seen in the Chinese market, and the patterns are relatively simple. However, we have also noticed that large fashionable supermarkets like IKEA have also begun to prominently display colored napkins imported from Europe, which are much more expensive than pure white products. Obviously, printing has brought high added value to napkin products. For printing, this also means a new profit growth point, which deserves everyone's attention

printing equipment

tissue flexographic printing machine adopts cascade or satellite structure design, and the whole machine includes uncoiling, printing and wiring processing parts. From unwinding, through printing, folding, embossing, fragrance addition, counting to the finished tissue, the whole processing process is fully automatic. Flexographic printing equipment adopts a combined design, which is quite flexible in configuration. The number of all units, including printing units, can be increased or decreased, and the printing factory can customize it according to the needs of its own business

tissue flexographic printing machine is characterized by high speed and high output. Taking the tissue flexographic printing machine produced by omite company as an example, the format is 500~2740mm, and the printing speed can reach 600~700 meters/minute; The printing unit can be configured to 8 color decks at most; In the paper output part, according to the size of the output, there are several paper receiving methods such as single paper path, double paper path and even 8 paper path to choose from. Figure 1 shows a sample of tissue printed by the omite tissue flexographic press

in the process of tissue printing, due to the particularity of tissue materials, the control of printing tension is one of the key factors affecting the quality of prints. Many high-end flexographic printing equipment have adopted shaftless drive technology. Independent DC motor control is adopted in each unit of unwinding, printing, embossing, folding, etc., and equipped with multiple floating rollers and paper clamping rollers under digital control, which greatly improves the tension control and registration control effect of the equipment. Secondly, the drying performance of the equipment is also very important. Tissue flexographic printing machines mostly adopt infrared, hot air or a combination of both drying methods, and are equipped with a water-cooled roller scheme, so they can achieve better drying effect and meet the requirements of products

however, there is still such a problem in tissue printing. Because the tissue material itself has many paper hairs and poor surface strength, it is easy to lose powder and hair, adhere to the printing plate and gradually accumulate, which will cause dirty and blocked plates, and must be stopped for cleaning. To solve this annoying problem, many manufacturers install vacuum cleaners in the printing unit to solve it, or cooperate with special doctor blades to reduce the incidence of such problems. The company adopts a wheel pressing device, closed double knives and vacuum cleaner, which basically eliminates this phenomenon. At the same time, the company also provides a device for cleaning printing plates without stopping the machine, which can reduce downtime and improve production efficiency

post process is a very important part of tissue flexographic printing. Taking folding tissue as an example, tissue folding is very particular, requiring four sides to be square and edges to be clear in the development process of more than 40 years. In this process, tension control is particularly critical. The folding methods of paper towels are flexible and diverse. Figure 2 lists some folding methods of omite paper towel flexographic printing machine

embossing is also a very important link in the production process of paper towels. Embossing can improve the softness and hygroscopicity of paper towels. At the same time, the concave convex patterns of different patterns also add beautiful effects. There are many ways of embossing, such as point-to-point, steel to steel, steel to paper, steel to rubber, said Jin Yong, an academician of the Chinese Academy of Engineering in an interview recently, which can also be divided into partial embossing and full embossing

the strong development momentum of tissue flexographic printing has attracted people's attention. The U.S. FTA report proposed that although the data about the tissue business of flexographic printing has not been included in the official statistics of the North American flexographic printing market in 2002, from the perspective of the tissue printing manufacturers that account for 5% to 8% of its membership, tissue printing represents a new and powerful profit growth space, This has been in the downturn in the North American flexographic printing industry. Many tissue flexographic printing enterprises are full of confidence in the current and future tissue printing market. Statistical data show that: from now to 2, visual inspection of the sample gauge will lead to a certain deviation; In 2005, the printing business of tissue and napkin will grow steadily by 3% to 5% per year

these market trends can be used as a reference for domestic manufacturers engaged in flexographic printing industry and those who intend to invest in flexographic printing, so as to jointly expand and strengthen the flexographic printing market and win a broader development space
