4. Trends in the US market
The US market is different from the EU, and the flexographic printing system has a very high ratio, which is differentiated according to the purpose and introduces the trend of the US flexo market.
(i) Flexographic printing for shrink-wrapped bags
Thirty years ago, this business was mainly undertaken by gravure printing. At that time, it faced three kinds of shrinking materials of PVC, PET and OPS. Today, 70% of shrink film is PVC. At the time of shrinkage, there is about 75% shrinkage, and the ink is required to comply with this shrinkage.
(ii) Flexographic printing for standing pouch
Open bag is a unique packaging form in recent years, and the market demand has increased. It has been growing at a rate of 17% since 2006. Its sales are expected to reach US$1 billion, most of which are needed for medical diagnosis. The rest is that the food market is dominated by confectionery products, and the demand for distillation cans will increase.
(iii) Secure printing for the field of sealing trademarks
In 2004, a new wave of R EID was added to corrugated paper. Although the cost has increased, the demand for it has been identified.
(iv) Flexographic printing for the field of thick cardboard
In recent years, many types of printing machines capable of printing from cardboard to plastic film have been produced. This has no obstacles to the thick paper printing that relies on online production for final processing. Therefore, the effectiveness of the flexographic system has been shifted from small batch to medium batch, which can be reduced by 40 compared with the previous printing and processing separation methods. % of the above works.
(v) Flexographic printing for thin fabrics and nonwovens
In the market for thin fabrics and nonwovens for lightweight paper, the opportunity market and new use areas that use these unique materials to create added value are growing. The printing of non-woven fabrics is different from the printing of thin fabrics, and it is not the same as the printing of paper and fibers. This has increased as a demand for household products, bathroom applications, etc. since 2004. There are two trends in the development of non-woven products for flexographic printing companies. One is to expand the demand for similar thin fabrics and paper towels, and the other is for the medical field, especially for the color of the hospital blue. Non-woven fabrics for hospital use are promising.
(vi) UV/EB flexographic printing
The remarkable growth of UV/EB technology has penetrated into food packaging applications. Under the supervision of solvent-free, relying on thermal drying to reduce energy consumption, and thus superior adhesion to plastics and metal substrates, food packaging has become UV/EB technology. The biggest use.
Third, the latest technology trends in flexographic printing
At present, as a new technology trend of flexographic printing, in recent years, there has not been any innovative technology in printing presses, peripheral equipment, linkage processing machines, plates, etc., but it is suitable for high quality, high productivity, high added value, and environmental protection. Printing systems are constantly being introduced. Here are just some of the new technologies that have been marketed.
1. Flexographic printing machine
Flexographic printing corresponds to high-quality requirements and relies on the large components of the printing press. Each printer manufacturer has painstakingly developed the conversion from the shared press (CI) type to the wide-format machine using an electronic control mechanism system to change the original gear transmission. It is a gearless transmission using a servo motor.
Listed below are six utilities
‧No scallops
‧No need to replace gears when encountering specification changes
‧Can be steplessly repeated control because there is no tooth pitch
‧Because no gear removes the gap, eliminating noise and vibration
‧The inventory gear is no longer needed
‧Elimination of gear wear accidents caused by friction
2. Automation around the press
Manually operated operations on the periphery of the press have been converted to mechanization and automation to achieve high efficiency. The new device is described below.
‧Automatic ink washing device
‧Automatic control of ink viscosity device
‧With automatic unloading function that can quickly replace plate roll and anilox roll
‧Automatic cleaning plate roll and anilox roller device
‧Roll paper lifting device
‧Automatic inspection of shortage devices
‧Automatic control of press device
‧Automatic detection of color devices
