Recent years, global Paper products Package Industry developed rapidly, Box , Carton Significant increase in production capacity. Industrial output in the world packaging, paper Packaging Products More than 32%, in Europe, paper and paperboard Consumption As high as 41%. 2000, per capita consumption of paper and board: United States 331.7 kg, 249.9 kg in Japan, Taiwan, 229.4 kg, 28.4 kg in China.
2000 China’s import of paper, cardboard and Pulp Up to 13.03 million tons (about 60 billion U.S. dollars), accounting for paper and paperboard consumption in China was 66.7%. In recent years, packaging industry growth rate of about Print Twice the industry. 2000 Guangdong Province Packaging industry sales of 50 billion yuan, of which Paper Packaging Products reached 18 billion yuan, packaging and printing 14 billion yuan.
With the further enhancement of environmental awareness among the people, boxes, cartons, paper bags, paper cups, paper tube packaging, etc. Container Widely applied in the world in Europe, for a variety of Juice , Milk, cooked food, fast food, snacks, etc. Beverages And Food The carton packaging everywhere. According to Tobacco Department the information reported, the domestic share of the hard boxes for packaging of cigarettes reached 56%.
As people Life Level and the degree of automation, the continuous improvement of packaging, not only on the box / carton substantial increase in demand, but also color folding cartons / multi-color printing carton quality and precision is also a higher demand. To avoid the automatic folding Folder gluer On the waste, so that high-speed folding carton Packaging Machine Automatically complete the open, forming, filling, sealing and other process, requires not only reasonable carton structural design but also to ensure adequate film box cutting accuracy and precision folded and glued boxes. Multi-color printing, short version of live cases to improve print quality and precision, lower processing costs, is also a carton packaging printing enterprises face market pressures and challenges. Therefore, only the application of modern processing methods and new technologies in printing and paper packaging Postpress Continuously improve processing automation equipment, reducing equipment adjustment time and the living conditions of the auxiliary preparation time, and constantly adapt to new market changes, to meet the requirements of different users in order to improve the competitiveness of packaging and printing companies. CAD technology
paper containers The international market, the more popular CAD carton structure Software , In addition to the interactive graphics software with commonly used basic functions (quality, and rapid completion of the generation graphics, edit, modify, label size, etc.), we must also meet the special requirements box design, convenient to call the box chip graphics library and select box-shaped structure of satisfaction, enter the box dimensions (length, width, height) and board thickness, it can immediately display or print box chip chart, automatic nesting and cutting out pieces nesting box plans, printing profile Figure and backing (the bottom mold) process map; when the user request or call the box chip chart, just enter the sizes of cardboard and marker clearance, marker and can compare different layout options to show optimization of cutting nesting and related parameters (such as the number of nesting, cardboard utilization, etc.).
Addition to selection criteria box type, change the box shape, it can also design any special box-type, three-dimensional rotating boxes, showing the process of opening and closing cartons; for different cutting edges, creasing and slotting broken line parts of the corresponding line types should be selected to control the sample box, die-and bottom-mode (backing) version and the model Cutter With the Make Increased die-and backing versions of the production of precision and accuracy of carton.
Paper packaging Printing Technology
In the field of packaging and printing paper, offset Offset printing , Toppan flexo, Gravure , Screen Printing The coexistence of a variety of print, its own characteristics. Most of the corrugated carton used in offset printing method, also using the platen and sheet-fed screen printing Gravure Approach; in web printing, gravure and flexo methods most used, there is also an offset and screen printing methods, also in a print Production Line At the same time using some combination of printing methods. Box color printing color is generally between 2-8 of them to use up to 4-6 colors. Folding cartons, particularly PCS more use spot color, the color class number of mostly 6-8 color. Sheet-fed offset press The color group number is usually 4-color, basically no more than 5-6 colors, and multicolor web press including gravure, flexo and screen printing) use has increased rapidly, and some color class numbers reached 8-10 color.
