Overview of Packaging and Printing Equipment (I)

Packaging and printing of newspapers and the printing of newspapers have driven the rapid development of the printing industry. Today, the printing of daily newspapers has entered a relatively stable period of development driven by the advertising industry. The development momentum of packaging printing is still very strong. It is mainly manifested in the expansion of the packaging of corrugated paper packaging products to large-scale household appliances, assembled furniture, mechanical and electrical products, fruits and vegetables, and fresh seafood, not only in volume, but also in black and white printing. Developed to color printing. Because of the poor strength of corrugated packaging products, the introduction of honeycomb paper packaging products in recent years has expanded the application market for such packaging materials. Another type of multi-layer composite paper and white paperboard packaging materials are used more widely and have been used for internal and external packaging of mechanical and electrical products, foods, medicines, clothing, shoes and hats, household goods, tobacco and alcohol. Another is the widely used plastic film packaging materials, mainly used in the soft packaging of food, medicine, household items. These packaging products are everywhere and go deep into every corner of life and production. Of course, the printing and packaging machinery equipment and manufacturers that produce these printing and packaging products are also growing at the same pace. The development of printing and packaging machinery can be seen from the following three printing materials processing equipment and surface decoration equipment.
Corrugated paper printing equipment Corrugated paper printing equipment is mainly represented by corrugated paper printing slot machines. The corrugated paper printing slotting machines include Shanxi Beiren Printing Machine Co., Ltd., Shanghai Electric Group Printing and Packaging Machinery Co., Ltd. Carton Branch, Xianyang Hefeng Printing and Packaging Machinery Co., Ltd., Lake Beijing Light Industry Machinery Co., Ltd. and more than 30 companies. Home business. The corrugated printing slotting machine has a printing width of 1600-3150 mm, a printing thickness of 2-11 mm, and a printing speed of 90 shots/minute-180 shots/minute. In a printing process can be completed 1-4 color printing, indentation, grooving, playing clasp hands, air hole, cut angle, slitting and other processes. The level of corrugated paper printing slot machines in foreign countries is higher than that in China, such as the maximum printing width of Korea DY Machinery (strain) 4500mm and the printing speed up to 250 sheets/minute. Corrugated paper post-printing equipment: Flat-press automatic die-cutting machine, die-cutting creasing machine, round press die-cutting machine, round-pressing die-cutting machine, separator, paper cutter, cross cutting machine, laminator, automatic packaging machine , jet printers, automatic folding and sticking box machines, etc. These major equipment manufacturers include Shanghai Yahua Printing Machinery Co., Ltd., Hebei Yutian Machinery Co., Ltd., Beiren Group Co., Ltd., Xianyang Hefeng Printing and Packaging Machinery Co., Ltd., and Shanghai Shenweida Machinery Co., Ltd. Company, Changchun Printing Machinery Co., Ltd., Sichuan Zhongjiang Litong Machinery Co., Ltd., Qingdao Meiguang Machinery Co., Ltd., etc. According to the statistics of sales volume of 44 corrugated equipment manufacturers in the industry in 2001, 18 corrugated printing slotting machines, 127 automatic die cutting machines, 277 automatic hot stamping die cutting machines, 689 flat pressure creasing machines, and paper cutting With 2,703 units, the comprehensive growth rate by sales amounted to about 8%, and the enterprises with better exports were Shanghai Yahua and Shaanxi Printing Machinery.
Second, the status of flexographic printing presses The situation of flexographic printing presses has been described in detail in the article “Development of Flexo Printing Press Manufacturing Industry” in the “Printing Materials Business in China” in the 11th issue of 2002, which is not repeated here.
There are about 10 domestic manufacturers of web flexographic printing presses: Beiren Fuji, Shanghai Ziguang, Shaanxi Yinji, Shaanxi Black Bull, Shanxi Taihang, Rui Andonghai, Jiangsu Baonan, Wenzhou Shenli, Guangdong Samsung, Shandong Qingzhou and so on. The sheet-fed four-page flexographic printing machine was also launched in Xianyang Hefeng in 2001, making it an option for printing shorter editions.
The flexographic press import had a climax and has maintained a relatively high growth in recent years. At present, only 240 narrow-format flexographic printing machines have been installed in China. Exports of flexographic printing presses are also growing, mainly corrugated paper printing equipment.
Third, gravure printing equipment For the broad market of flexible packaging, there are many kinds of gravure rotary printing presses of various specifications and grades. According to incomplete statistics of four companies, in 2001, a total of 55 gravure printing machines were produced and sold. The main products include slitting machines, coating machines, sealing machines, and heat sealing machines. In 2001, the company produced 117 slitters and 40 coaters. The import and export of gravure printing machines from 1998 to 2001 (see Table 1). (To be continued)
