The development of new technologies for paper packaging and printing

In recent years, the global paper product packaging industry has developed rapidly, and the production capacity of cartons and cartons has increased significantly. In the world's packaging industry output value, paper packaging products exceed 32%, and in Europe, the consumption of paper and cardboard is as high as 41%. Per capita paper and cardboard consumption in 2000: 331.7 kg in the US, 249.9 kg in Japan, 229.4 kg in Taiwan, and 28.4 kg in mainland China.

In 2000, China imported 13.03 million tons of paper, paperboard and pulp (about 6 billion US dollars), accounting for about 66.7% of China's paper and paperboard consumption. In recent years, the growth rate of Hong Kong's packaging industry is about twice that of the printing industry. In 2000, the sales of packaging industry in Guangdong reached 50 billion yuan, of which 18 billion yuan was for paper packaging products and 14 billion yuan for packaging and printing.

As people's environmental awareness is further enhanced, packaging containers such as cartons, cartons, paper bags, paper cups, and paper tubes are more and more widely used in Europe. They are used in various juices, milk, cooked food, fast food, snacks and other beverages. Food cartons are everywhere. According to relevant information reported by the China Tobacco Department, the proportion of domestic hard-packed cigarettes has reached 56%.

With the continuous improvement of people's living standards and the degree of automation of commodity packaging, not only the demand for cartons / cartons has increased greatly, but also the higher quality requirements for the printing quality and processing accuracy of color folding cartons / multicolor cartons . To avoid rabbits producing waste products on the automatic folding and gluing machine, so that the folding carton can automatically complete the processes of opening, forming, filling, and sealing on the high-speed packaging machine. Not only the reasonable design of the carton structure but also the box must have sufficient mold Cutting accuracy and folding paste box accuracy. Multi-color printing, the increase of short-form jobs, improving printing quality and processing accuracy, and reducing processing costs are also market pressures and problems faced by carton packaging and printing companies. Therefore, only by applying modern processing methods and new technologies, the Shanghai printing plant continuously improves the degree of automation of equipment, reduces the adjustment time of equipment and the auxiliary preparation time of live parts during paper packaging printing and post-press processing, and constantly adapts to new changes in the market In order to meet the requirements of different users, we can improve the competitiveness of packaging and printing enterprises.

2. CAD technology of paper packaging container

In addition to the basic functions of commonly used interactive graphics software (high-quality, fast completion of graphics generation, editing, modification, dimensioning, etc.), the popular carton structure CAD software on the international market should also meet the carton design Special requirements, easily call the box graphics library and select a satisfactory box-shaped structure. After entering the box body size (length, width, height) and cardboard thickness, the box structure diagram can be displayed or printed immediately, and the material is automatically discharged, and Output box die cutting layout drawing, printing outline drawing and backing (bottom die) processing drawing; when the user designs or calls the required box sheet structural drawing, as long as the paper board size and discharge gap are input, the material can be discharged And compare different layout schemes, display optimized die cutting layout diagram and related parameters (such as the number of layout, cardboard utilization, etc.).

In addition to selecting the standard box shape and changing the shape of the carton, you can also arbitrarily design a special box shape, rotate the carton perspective, and display the opening and closing process of the carton; for different cutting edges, indentation lines, and slotted and broken parts, you should choose Corresponding line types, to control the production of carton samples, die-cutting plates, bottom mold (backing) plates and die-cutting tools to improve the processing accuracy of die-cutting plates and backing plates and the precision of carton production.
