Corrugated boxes upstream and downstream industries (below)

The third is the production line of corrugated paperboard, which is characterized by: combining various equipments to integrate the entire corrugated board production process and linking the entire corrugated board production process together to achieve automation and continuous production. The corrugated board produced is smooth, has low moisture content, has a good shape, good quality, and high speed. It provides good quality assurance for the carton forming process.
At present, the specific number of corrugated box enterprises in China cannot be estimated, and there are nearly ten thousand carton enterprises of a certain scale. With the development of the market economy, the competition is fierce, and the survival of the fittest has led to the rapid development of some carton enterprises, which have become large sales accounts of 100 million yuan. Such as Zhejiang Shengda, Shangfeng, Shanghai's Asia, United, Huali, Xinqing, Jifeng and Jiangsu Xiantai, Shanghai reached 100 million yuan in carton enterprises. The carton industry in Shanghai has undergone a restructuring of its internal structure. It has implemented a new pattern of “cooperative manufacturing and decentralized manufacturing” in the industry. Currently, most small carton companies purchase corrugated cardboard from large companies with corrugated board production lines, and the industry division has overcome The “small and complete” production model not only exerted the advantages of good quality of the large-scale production lines, improved the operating rate of advanced equipment, but also gave play to the advantages of quick turnaround, small-batch production, and multi-specification of small plants, greatly reducing the loss of raw paper and improving both parties. The economic benefits to achieve a win-win situation. The traditional stand-alone production and single-faced corrugated cardboard units were basically eliminated, and the entire industry generally improved productivity.
Since the 1980s, China has begun to introduce advanced equipment for carton boxes from Japan, Italy, and Taiwan. In the 1990s, it imported advanced international equipment from developed countries such as the United States, Germany, and France. It then copied and gradually developed, and now it can produce advanced products. Corrugated cardboard production line and water-based printing slotting machine, flat pressure die-cutting machine and other equipment. At present, the development of the carton market indicates the direction for carton equipment to further develop high-end, high-speed, high-efficiency, wide-format, high-tech carton equipment. At present, there is still a considerable gap between the domestic production of corrugated board production lines and the international level, and it is necessary to continuously improve the design structure, production speed, electrical appliances, steel materials and processing accuracy, and then spend 10 years to catch up with the international advanced level. It is possible.
Experts suggest carton machinery and equipment manufacturers: First, the corrugated board production line should research and develop high-speed adsorption type roller, improve the stability of equipment operation, reduce failures, and appropriately limit the manufacture of single-faced corrugating machines with low technological content and high efficiency and low efficiency. Second, faced with the rapid development of foreign mini-corrugated cardboard and the actual needs of China, carton machinery and equipment manufacturers need to increase the development and production of micro-corrugated roller efforts to promote the development of China's mini-corrugated carton; Third, equipment and machinery companies must Adjust the production structure, overcome the “big and full”, and adopt a specialized model to achieve concentration and excellence.
The printing quality of corrugated cartons still needs to be improved. As the society continues to develop and standard consumption levels increase, the printing of corrugated cartons must gradually develop in the direction of high-end, high-quality, multi-color, and strong visual effects. In the direction of multi-color printing of colored noodles, it is also based on commodity packaging instead of transport packaging. The use of whiteboard cattle card to replace the box board cattle card, to achieve bright colors, good gloss, beautiful and so on. To achieve the above standards, high demands are made on plate making and printing inks. In high-grade carton printing plates, flexible plates must be used instead of rubber plates, and high-quality aqueous inks must also be used to achieve luster, bright, fast drying and high-speed production.
In addition to plate making and printing ink, higher requirements have been put forward for water-based printing slotting machines, achieving high-speed, high-efficiency, and multi-color printing. Accuracy of color registration is plus or minus 0.5 mm. The printing slotting machine has made great progress and improvement in China. Shanghai Dinglong and Guangdong Oriental's production of water-based printing slotting machines have reached China's advanced level and are sold at home and abroad. The improvement of printing quality is an important condition for the quality of the entire carton. If the trimming, slotting, pressing, and cutting angle processes use a die-cutting process, it can be neat, smooth, and beautiful.
Corrugated box applications need to expand the general use of corrugated board is to make cartons, cartons, cushions and so on. According to industry insiders' prediction, as the whole society attaches importance to environmental protection, paper packaging belongs to green packaging, which not only has use value, but also has recycling and recycling value. In the future, a large number of goods will be packaged in cartons and cartons. The corrugated box industry should expand its services to cartons and cartons.
It is understood that the traditional service objects of corrugated box packaging are outer packaging and transportation packaging. Should actively develop new products, such as micro-small corrugated cartons, supermarket shelves, honeycomb cardboard, from the breadth and depth of development.
Corrugated carton packaging should also actively develop into sales packaging. With the development of commerce, the living standards of consumers have increased, and the demand for corrugated boxes with higher strength and good advertising functions has increased. The demand for fine printing has become higher and higher.
The kraft linerboard transport packaging will be gradually replaced by the whiteboard kraft color-printed cartons to realize the integration of internal and external packaging products.
Industry experts believe that the corrugated paper box packaging industry should speed up the transformation of technical equipment, so that China's corrugated paper box industry better based on the packaging field, in order to make our country from a packaging power to develop into a packaging power.
