Brief analysis of the development prospect and space of flexographic printing technology in sales packaging core tip: as a representative of the world trend of packaging and printing, flexographic printing technology is one of the most important printing techniques in the 21st century. Flexographic printing technology has developed rapidly abroad, especially its obvious advantages in improving the environment, especially in the printing of packaging materials. Now, domestic enterprises use e-corrugated more, such as Siemens and other large enterprises have put forward the requirement of using g-corrugated and other smaller corrugated

(1) micro corrugated packaging has many advantages

in the United States, the consumption of digital and small household appliances for micro corrugated packaging is increasing at a rate of 2% per year; In Europe, the consumption of micro corrugated packaging was estimated to account for 12% of the total packaging in 2004. According to statistics, the current output of micro corrugated board in the world market accounts for 8% of the total output of corrugated board. It is expected that it will continue to grow in the next five years, with an annual growth rate of about 20%. In terms of ridge type, it is developing towards g-ridge and n-ridge. Because micro corrugated packaging has the advantages of high compressive strength, exquisite printing and so on, it has been recognized by users, and the consumption is increasing steadily. At present, domestic enterprises apply e-corrugated more. For example, large enterprises such as Siemens have put forward the requirement of using smaller corrugated such as g-corrugated. Small digital household appliances of enterprises such as BenQ, Motorola, Haier, Philips and Sony all use micro corrugated packaging

1. Micro corrugated packaging saves 20% of the cost. Compared with solid cardboard, low gram weight, high-strength micro corrugated cartons have better cost performance, so the packaging cost is more economical and reasonable. Under the same use conditions, it is mainly for aerospace, automobile, public transportation, oil and natural gas and other industrial end markets with harsh environment. Due to its low gram weight, micro corrugated packaging is in line with the current development trend of lightweight packaging

2. The compression resistance and bursting resistance are more prominent. While reducing the cost, micro corrugated packaging also ensures the superior performance of cartons in other aspects. Compared with large corrugated packaging such as b-corrugated, micro corrugated packaging has lower corrugated height, more corrugated number per unit area, denser corrugated types, and stronger structure. Therefore, when using the same base paper and the same pressure, it has more obvious advantages in terms of pressure bearing strength and buffer capacity against parallel pressure. For example, the rupture strength of e-corrugated packaging box can reach 11kg/cm2. Generally, the pressure bearing capacity of the outer packaging of paper products is at least times greater than the weight of the packaging. In terms of the choice of base paper, both stiffness and bursting resistance are adopted. To a large extent, grey white board with good performance is used as the face paper of micro corrugated packaging box. This 350 gram base paper makes the protective performance of the box more prominent and effectively ensures the quality of products during transportation

3. Ink and UV varnish ensure fine printing. Fine corrugated packaging has a good degree of pressure, so it has a very strong color expressiveness. Coupled with the high stability of gray background whiteboard, it can well ensure the printing adaptability. It adopts five-color printing with four, no refutation, rust and other scenes. The pattern is exquisite, the color is gorgeous, and has a strong visual effect, and the excellent printing effect well highlights the quality of the content. In order to ensure the printing quality, water-based ink with good wear-resistant effect is selected and coated with UV varnish to protect the printing

(II). The development prospect and space of flexographic printing technology in sales packaging

some European and American countries have recently repeatedly reiterated that according to the safety of raw materials and packaging or the use of recyclable packaging materials, tax-free and low tax preferences are given to encourage the use of green packaging. Some countries require that if this standard cannot be met, they refuse to import

as a representative of the world trend of packaging printing, flexographic printing technology is one of the most important printing techniques in the 21st century. Flexographic printing technology has developed rapidly abroad, especially its obvious advantages in improving the environment. Especially in the printing of packaging materials, flexographic printing accounts for 70% of the packaging market in the United States, 35% of the total printed matter in Europe, and continues to develop. Flexographic printing has a trend of surpassing lithography and gravure printing in the printing market share of the packaging industry. Therefore, in the United States, this printing technology is called packaging printing. In developed countries in Europe and the United States, it is considered to be the best and most promising printing method on the earth. According to the latest estimates, more than 90% of corrugated cardboard in foreign countries is printed on flexographic machines. Flexographic printing represents about US $90billion of the packaging and printing industry in the United States, and the total market share of packaging hot spots in Canada is estimated to account for 2.5% of its GOP, about US $20billion

flexographic printing is in the middle and high-end market in terms of film production, supply mode and printing method before printing. It integrates the characteristics of three printing processes: flat, concave and convex printing. It is very suitable for printing 150 lines, colors or more high-quality color prints

the ink layer thickness of printed matter makes the product have the characteristics of rich layers and bright colors, which is especially suitable for the requirements of packaging and printing. In particular, flexographic post printing is a low-cost high-quality carton printing scheme; It has: 1. Lasting and consistent precision overprint accuracy; 2. Be able to flexibly accept orders in various batches; 3. Low scrap rate and low cost; 4. No matter the size of the carton, the thickness is uniform; 5. Fast and low-cost order replacement; 6. Simple process flow and operation mode; 7. Large output, fast speed and high return; 8. It is an environmentally friendly and energy-saving printing method, providing technical support for the upgrading of carton packaging

at present, the plate making cost of a set of packaging cartons is generally between 4000 yuan and 8000 yuan. Flexographic printing plate adopts flexographic laser digital resin format to improve the accuracy, dot, resolution and printing volume of overprint, prevent color difference and achieve a beautiful three-dimensional feeling. If a resin plate with a thickness of 3.94mm is used for printing, the production cost of the flexible plate per square centimeter is about 0.093 yuan and 0.16 yuan. If the printing plate is made by ourselves, the cost can be saved%
