Development and Application of Nano Packaging and Nanomaterials

The application and development of nanotechnology and nanomaterials have provided a good opportunity for development for the packaging industry in China. We now introduce some preliminary concepts of nanopacking for reference by our colleagues.

1. The definition of nano packaging: Although there is no accurate definition of nano packaging, but from the perspective of nano science, nano packaging reflects the use of nano-materials, nano-technology for packaging products nano synthesis, nano addition, nano modification, make it available The general name for the new packaging features of nanostructures, scales, and specific functions.

2. Nano packaging has four elements: nano packaging material elements; nano packaging container elements; nano packaging technology elements; nano packaging information elements.

3. The object and task of nano packaging research: study the movement state and law of nano packaging materials in the process of logistics, the law of the physical properties of nano packaging materials and the preparation technology; study the relationship between nano packaging and multi disciplines, and propose a new packaging concept , Improve and create new packaging technology and decoration technology, shorten the process of engineering, industrialization and commercialization of existing packaging companies and nano-packaging.

Fifth, nano-coating materials: Binary synergistic nano-interface material is to promote the binary synergistic promotion to the nano-interface, discuss the new interface properties, super-dual interface characteristics of the material, so that the material on the macroscopic surface is the same in a layer of stable gas film The oil or water can not be in direct contact with the surface of the material, so that the surface of the material exhibits an extraordinary double hydrophobicity. At this time, the contact angle between the droplet or oil droplet and the interface tends to be maximum. In the area of ​​packaging materials, paper products, cartons, films, etc. have also achieved surprisingly super-hydrophobic effects.

Six, nano-luminescent materials and anti-counterfeit printing: a new type of nano-luminescent materials, can be self-luminous in the dark for more than 12-24 hours after a few minutes of light, its luminous intensity and maintenance time is more than 30 times that of traditional fluorescent materials, and materials It is non-toxic, harmless and does not contain any radioactive elements. Its stability and weather resistance are excellent. Can be used endlessly.

Utilizing the new wide-area laser holographic anti-counterfeiting and packaging film materials and manufacturing technology, R&D and industrial production of high-performance anti-counterfeiting and packaging film products suitable for the Chinese market have great market potential, and the equipment cost and investment are moderate.

VII. Nano Packaging Machinery Parts and Devices

(1) Carbon nanotubes have high mechanical strength and high thermal conductivity. Due to their extremely large length-to-diameter ratio, they can produce any part with a complex shape. At present, printing and packaging machinery parts, such as gears, ceramic bearings, nano ceramic rollers, and electric engraving rollers, which are made of inexpensive nano plastics, have begun to replace metal materials.

(2) Many sensors are used on offset presses. There are several offset press manufacturers in China that use nano-magnetic switches and sensors. Compared with the Hallo sensors and Hall-effect sensors used in the past, they have many advantages.

8. Nano-Typography: At present, the semiconductor industry cannot produce parts smaller than 100 nanometers, and nanotechnology must be used to break this boundary. Will work on the 93nm lithography technology in the future:

(1) Improve the technology for carrying out external line printing;

(2) Near X-ray lithography;

(3) Electron beam printing.

The application of nanotechnology in packaging and printing is far more than mentioned. The development of nanotechnology will greatly change the traditional industries, and it can be predicted that in the near future, nanotechnology will bring tremendous changes to the packaging and printing industry.
