Corrugated carton is a very good packaging material. It can be made of paper, wood, paper, plastic, and paper materials can be recycled. It is a green packaging material. Therefore, it is favored by the modern society that attaches importance to environmental protection and has a good development prospect. The development of the carton industry will inevitably lead to the development of the paper and machinery manufacturing and auxiliary materials industries. From this perspective, corrugated paper and machinery manufacturing need to accelerate the pace and closely follow the rolling development.
1. The gap in the corrugated paper base was seriously affected by rapid economic growth, further development of the retail market, and improvement in consumption levels. It is estimated that by 2005, the annual consumption of paper and paperboard in China will reach 50 million tons, of which the corrugated paper market will consume 15 million tons, compared with foreign countries. Referred to, the corrugated paper used in China is generally high-quantitative, and there are few high-strength corrugated base papers. Due to the lack of wood pulp and value-added paper, many paper mills are reluctant to produce high-strength corrugated base papers and generally produce low- and medium-strength corrugated base papers. And the scale is not large, so the high-strength corrugated base paper can only rely on imports. There are not many corrugated paper projects planned for expansion in China. It is reported that in addition to two new high-strength corrugated paper projects in Guangdong Xiaolong and Zhejiang Jingxing, there will be a gap of at least 1 million tons by 2005. Currently, the import volume of high-strength corrugated paper is still growing.
At present, the supply of high-strength corrugated base paper in China is insufficient, and the demand is large. The current corrugated paper supply system based on middle- and low-grade products cannot meet the increasing demands of users for product quality, so only a large amount of high-strength corrugated base paper is available. Rely on imports. There are three main reasons for this situation: First, due to the low value-added value of corrugated paper for a long time, paper mills that produce packaging paperboard generally favor kraftlinerboard, whiteboard paper and other products with high added value and large demand. There are not many corrugated paper projects planned for expansion. Second, the rapid development and improvement of domestic paper product packaging has boosted the demand for domestic high-strength corrugated base paper and kraft linerboard. Third, the recent weakness in the international market for corrugated base paper exceeds supply, while the supply of high-strength corrugated base paper in China is in short supply.
From the perspective of market demand, it is a major trend for domestic development of high-strength corrugated base papers to develop in the direction of low quantification, high speed, and full specifications. The demand for medium and high-strength corrugated base papers will increase, and the price of corrugated base papers will increase. Currently, reducing the cost and reducing the basis for the production of corrugated base papers are two major themes.
Second, the development direction of corrugated board Corrugated board is from the paper, paper, paper and corrugated core paper processed into a wave of corrugated paper through the formation of corrugated cardboard, according to the requirements of commodity packaging, corrugated board can be processed into a single layer, three Layers, five layers, seven layers, nine layers, and other corrugated cardboard, after the printing, grooving or die cutting to form a carton. In the past decade or so, according to the needs of environmental protection and the requirements of relevant state policies, there has been a tendency for corrugated boxes to gradually replace wooden boxes and plastic boxes.
Based on environmental considerations and cost considerations, the quantitative basis of corrugated board, including boardboard paper and corrugated medium, must be reduced. Traditional corrugated type A, B, C, D and E are mainly used in cartons with high strength requirements. In recent years, F, N, and G corrugated corrugated media have been produced on the market. Their strength is much lower than that of conventional corrugated media. , suitable for the use of low volume corrugated paper. It is now able to produce 90-115 g/m2 of corrugated paper. It is expected that 60-90 g/m2 of corrugated paper will be produced in the future. As a result, the ration of corrugated board is reduced from the original 1000-1100 g/m2 to the present. At 600 g/m2, corrugated board in some countries is only 500 g/m2. However, corrugated paperboard in China is currently highly quantified. Therefore, a considerable amount of high-strength corrugated paper must be imported each year, wasting a lot of resources.
Third, corrugated board machinery manufacturing At present, China's corrugated board and corrugated box production equipment generally has three categories. First, the traditional single machine is a single production process. It must be formed through dozens of processes such as batching, cutting, splicing, printing, tamping, gluing, slitting, grooving, chamfering, nail packing, and packing. Carton, this process was basically eliminated in developed regions such as Guangdong, Jiangsu, Zhejiang, Shanghai, Beijing and Tianjin.
The second is the single-faced corrugating unit, which was developed in the late 1980s in China. It is a major advancement to replace the traditional single-machine corrugated board production. It is adapted to small and medium-sized carton enterprises, and the production efficiency and product quality are improved one step better than stand-alone. Strong. With the development of corrugated board production lines, the production efficiency and product quality of corrugated single-sided units have fallen behind.
The third is the production line of corrugated board, which is characterized by: combining various equipment to integrate the entire corrugated board production process, linking the entire corrugated board production process together, and achieving 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 cartons in China cannot be estimated. There are nearly 10,000 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 for hundreds of millions of yuan, such as Shengda of Zhejiang, Shangfeng, Asia of Shanghai, United, Huali, Xinqing and Jifeng. , Jiangsu Xiantai, etc., Shanghai has reached nearly ten 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 realize double profit. The traditional stand-alone production and single-sided corrugated board units were basically eliminated, and the entire industry formed advanced productivity.
Since the 1980s, China began to introduce advanced equipment for carton boxes from Japan, Italy, and Taiwan. In the 1990s, advanced equipment from the United States, Germany, France, and other developed countries was introduced, and then it was copied and gradually developed. Now it can produce more. Advanced corrugated cardboard production line, water-based printing slotting machine, flat pressing die-cutting machine and other equipment. At present, the development of the carton market has pointed out the direction for carton equipment to further develop high-end, high-speed, high-efficiency, wide-format, high-tech cartons. 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.
It is recommended that manufacturers of carton machinery and equipment: First, the corrugated paperboard production line should research and develop high-speed adsorption-type tile rollers, improve the stability of equipment operation, reduce failures, and appropriately limit the manufacture of single-faced corrugating machines with low technological content and high consumption and low efficiency. Second, in the face of the rapid development of foreign micro-corrugated cardboard and the actual needs of China, manufacturers of carton machinery and equipment need to increase the efforts to develop and produce miniature corrugated rollers in order to promote the development of mini-corrugated cardboard boxes in China. Third, equipment and machinery enterprises must adjust their production structure, overcome the “big and total†equipment, and adopt specialized models to achieve the business concepts of concentration, excellence, continuous improvement, continuous improvement, constant innovation, and continuous development.
Fourth, the development of corrugated carton printing With the continuous development of society, the improvement of standard consumption levels, the printing of corrugated boxes must gradually develop in the direction of high-end, high-quality, multi-color, and strong visual effects. , It is to replace the transport packaging of goods packaging, to replace the board cow cattle white card 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 inks, higher requirements have been put forward for aquatic printing slot machines, achieving high-speed, high-efficiency, multi-color, and accurate color registration error of 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 aspect of the quality of the entire carton. If the trimming, slotting, crimping and cutting angle processes use a die-cutting process, it can be neat, smooth and beautiful.
Fifth, the development of corrugated carton The general purpose of improving corrugated board is to make cartons, cartons, cushions, etc. According to industry estimates, as the whole society attaches importance to environmental protection and paper packaging belongs to green packaging, it not only has value in use, but also has recycling and recycling value. In the future, large quantities of goods will be packed in cartons and cartons, and the corrugated box industry should expand the cartons and paper. Box service object.
1. The traditional service objects of corrugated box packaging are outer packaging and transportation packaging. Actively develop new products, such as micro-fine corrugated cartons, supermarket shelves, and honeycomb paperboard, and develop in both breadth and depth.
2. Corrugated carton packaging should also actively develop into sales packaging. With the development of commerce and the improvement of the living standards of consumers, the demand for corrugated boxes with higher intensity and good advertising functions is increasing in the market, and the demand for fine printing is getting higher and higher.
3. The transportation and packaging of kraft linerboard will be gradually replaced by the cartons printed by the whiteboard kilocalorie to achieve the integration of internal and external packaging products.
Therefore, the corrugated paper box packaging industry should make technical equipment transformation as soon as possible, so that China's corrugated paper box industry based on the packaging of large countries, for the development of packaging from a large country into a packaging power and efforts.
