Carton printing process and materials
Art paper gravure composite carton process, when the production of large quantities, without film, and requires good printing effect, low cost, you can use this process. This process is to use paper gravure printing machine printing thin coated paper, and then the printed coated paper and ordinary slag paper board or cardboard composite as a whole, carton paper, and then mounted on the carton forming normal.The process is characterized by:(1) the cost of making cartons is low. The main reason for the cost reduction is that the white board is changed into low weight coated paper, which is combined with cheap carton paper to reduce material cost.(2) beautifully printed. The gravure printing effect of paper is very exquisite.(3) gravure printing process is more complicated, and the cost is high, it is not suitable for printing, often revised carton products.(4) the operation and control methods of the printing process, such as paper compounding and box making, should be carefully explored and continuously accumulated and reasonably implemented. Otherwise, the waste rate will be easily increased.
Direct offset corrugated carton process, corrugated box direct offset printing technology has been relatively mature in foreign countries, it is corrugated cardboard directly in a special offset printing press. The utility model is suitable for processing thin corrugated boxes.This process can ensure the formability of the carton, and can complete the fine printing paper printing machine, but the price is more expensive, and the requirement of our country standard is not suitable, not suitable for carton industry to adopt in the near future, but in the next few years, the process may become China's high-end a new direction for the development of carton printing.
Flexo printing and gravure printing of corrugated carton processThese two processes are the first to roll paper printing paper, and then in the automatic corrugated cardboard production line to complete the production of corrugated cardboard. Carton printing quality and molding quality are relatively high, but the investment is relatively large, it is also not suitable for small batch production.In the domestic carton industry, three conventional corrugated carton printing methods are more common, and become the mainstream of corrugated box printing. And the new printing box system, due to equipment, materials, processes, operations and other technical hot spots have not yet been fully mastered, the investment is relatively large, the promotion of the difficulty is still relatively large. But in order to improve the quality of carton enterprises, reduce the total cost of cartons, to maximize profits and increase the competitive advantage in the market, it is imperative to adopt the new printing process.
Single-sided corrugated production line adopts plastic gravure printing process composite paper carton packaging, paper printing also need to be completed if the light coating film, and large volume production, can be printed on the paper, and the way for gravure printing gravure printing on plastic film, and with white plastic film and paper and then the first printed composite, and then complete the box according to the conventional carton forming process.The process is characterized by:(1) the cost of making cartons is low. When the production batch is large, the printing cost and the material cost of the facial tissue can be greatly reduced by the process. Because the paper does not need to be printed, the uncoated white board paper can be used so as to greatly reduce the cost of the facial tissue.(2) beautifully printed. Because the plastic gravure printing is adopted, the printing effect can be compared with the offset printing effect. The process requires special attention. In the process of printing, it is necessary to take full account of the plastic film size changes and deformation; otherwise, the carton paper will be inconsistent with the lower paperboard.
