In the field of printing, nano metal powder has shown good results in the paper. Paper is most commonly used in printing and packaging materials. Merits of its quality reflect the quality of printed matter. Fibers of traditional trees, bamboo and hemp are thicker. Particles of coating (such as calcium carbonate), fillers (kaolin) is larger. Some plastic ingredients have bad performance. So traditional paper has some drawbacks. It does not have the characteristics of waterproof and moisture proof. Although plain paper, offset paper and electrostatic copy paper have function of waterproof and moisture proof, the writing is not convenient and there are some special properties which can not be implemented. It affects quality of the print. With the rapid development of nano-materials science in recent years, nanotechnology applications in the paper industry become wider and wider. The new results continue to emerge. The nano-chemistry and nano-materials science relate to the paper manufactures. It might be the breakthrough in development of paper industry. It may result in improvement of print matter’s quality.

According to the current level of technology and paper’s e practical application, the metal powder can only be processed to the micron level. Because the diameter is relatively coarse, nanotechnology can change the metal structure, and you can change the characteristics of the metal powder. For the vast majority of metal if the metal processing to nanoscale metal powder structure will be destroyed during processing using mechanical methods of separation, so that you can greatly improve utilization and reduce manufacturing paper industry on the environment pollution.

In addition, the rapid development in science and technology today, the paper performance, quality, etc. will have higher requirements, in addition to conventional printing, writing paper, paper with special features have continued to increase demand. Nano metal powder material as a specialty paper manufacturing special additives, it is more and more attention has been paid. At present, in the paper industry, nano-materials is mainly used for water-resistant, anti-bacterial, anti-static, anti-aging and the development of flavored, flame retardant, color and other functions of paper, and there are some products to market. Nano metal powders used in the field of packaging and printing, it will completely change the face of the field of packaging and printing, packaging and printing has opened a new path.

Although nano silicon powder materials and nanocomposites has a good performance and a wide range of application in the paper sector, research and development of nano-metal powder is not mature and perfect. There are a number of issues need further study and solve, such as crushing, agglomeration and dispersion technology. They are still not ideal. The performance testing of nano-products and product standards should be further improved. But it can be predicted that with the lower cost of production of nanoparticles and species of functional nanoparticles increase, nanotechnology will play a greater role in the field of printing and paper industry. It will bring unlimited vigor and vitality for printing and related industries.
