In the field of packaging and printing, the application of nanotechnology to the development of nano-packaging technology and nano-packaging materials is gradually being paid attention to by people. Now there are some mature nano-technologies that can be used in packaging and printing fields.
Nano-scale transparent iron oxide series pigments have been successfully developed and have been rated as national key new products by the Ministry of Science and Technology. Its successful development has a major impact on the upgrading of traditional pigments in China. It can be applied to nano inks and nano water-based coating materials. Wait.
Nano-calcium carbonate preparation technology and technology have been successfully developed nano-scale light calcium carbonate, is an important inorganic filler, mainly used in high-grade ink, high-grade plastic, paper, special paper and rubber products.
MOD series nano high-performance inorganic antibacterial agent solves the worldwide problem of discoloration of inorganic antibacterial agents in applications. The 0.5%-2% added amount of packaging products has an antibacterial rate of 99.9% and can be applied to milk, Antibacterial beverage packaging, plastic products, functional coatings and special paper.
Polyamide 6 nano plastics are high-grade packaging film materials that can be used in food packaging.
Polyester PET and PBT nanoplastics have flame-retardant properties and relatively pure barrier properties, replacing the expensive polybutylene terephthalate (PBT) resin. Meet the food packaging requirements, can be directly used to blow beer, cosmetics bottles.
Vapor-phase silica is the only nanomaterial in the world that can be mass-produced industrially in the world, with its superior stability, reinforcement, viscosity and thixotropy in papermaking, plastics, advanced coatings, adhesives and seals. Agents, special inks, cosmetics, food preservation functions, copy paper and many other industrial fields are widely used. Especially in the application of plastics, adding polyester resin, epoxy resin, vinyl resin, can significantly improve product quality, facilitate molding operations, improve the molding process efficiency.
Scientists in our country have developed nano-micro magnetic switches and sensors, which have been widely used in the machinery industry and the automotive industry to improve the product's automatic control system to a new level. Many sensors are used on modern offset presses, such as automatic lift control of Feida paper stacks, gas pump air supply time detection, pressure-compression time detection, air gap detection, and ink volume control. There are several offset Printing Machine manufacturers in China that use nano-magnetic switches and sensors. Compared with the reed sensor and Hall sensor used in the past, it has many advantages.
Machinery for the quantitative packaging of nanomaterials has been successfully developed. This product is for nano-ultrafine powder materials in the packaging process is easy to agglomerate, bridging, low bulk density and other characteristics, covering the two utility model patents of the Packaging Machine to solve the nano-materials can not accurately and smoothly automatic quantitative packaging problems. The machine also has a unique feeding function from the bottom of the bag, which can prevent dust from flying in the packaging process. Due to the use of open-pocket packaging, the pouches are inexpensive and not easily damaged. Already put into use in nanomaterial manufacturers.
The above-listed scientific research results that can be applied to nano-packaging have been developed into commodities or semi-finished products, and some have completed pilot tests. The development of nano-technology will greatly change the traditional industries, as long as packaging and printing companies actively participate in the adoption of Solid, this effective application and promotion can form large-scale production and realize industrialization.
