Nano Packaging Technology Application Update

“Nano-packaging” is an emerging technology that has been available for more than 10 years. However, its development speed is very alarming, opening up a vast space for packaging new product development. The application of foreign "nano packaging" technology is mainly in four aspects: 1. Nano coating and tool materials have entered the market. The use of nanotechnology in high temperature, high strength, high toughness, good stability, transformation of traditional tools and workpieces. Finland and the United States cover nano-coatings on ordinary steel knives, and their hardness can be increased several times. Some developed countries in Europe and the United States have used nano-ceramic cutting tools as a target for the cross-century tool industry revolution and are now being converted from laboratory to industrial production. It is expected soon. This tool will become the main player in the market.

2. The combination of nanoparticles and resins has great appeal to the market. Several Japanese home appliance companies have done a lot of research in this area, and their results have been widely used in high-end appliances and packaging. 3. Nanomaterials are added as additives to other materials for modification, drawing the attention of the business community. 4. Nano-functional materials have a large potential market demand. Nano-materials have special optical and electrical properties, giant magnetoresistance, nonlinear resistance phenomena, etc., which have obvious characteristics that are not found in traditional materials, and have aroused widespread interest at home and abroad.

First, the application of nanotechnology in product identification

1. Trademark protection new technology. Currently, Israel’s Starboardechnologies develops a very cheap and reliable new technology for security marking. These images are invisible to the naked eye but can be seen through some special lenses. This image can be added using one of a variety of printing processes, including offset, gravure, and flexo. Prior to normal printing, the customer-supplied file is processed with special software. During this process, the pixels and line segments are subtly processed so that the information embedded in the image is not visible to the naked eye. These "hidden images Even if it can be copied or decoded, it is extremely difficult and costly, even if it is successfully copied and decoded. Because the scanner can only capture visible images, it can't get encoded data. One of the great advantages of this technique is that the required decoding lens is verified, neither power supply nor special chemistry. It is a uniquely configured image that is used for special conversion.

2. DNA markers and optical nano-stamps. German IdentifTe ChnoLogies has developed two other anti-counterfeiting processes. One type of molecular fingerprinting based on synthetic DNA is another type of “lock and key” that provides advanced protection. It can generate customers that are between 10th and 12th powers, 10th to 16th powers. The special code is printed directly on the folding cartons or other products; the second process uses advanced nano-coded anti-counterfeit labels, which are labeled with a tamper-resistant stamp with a label, and the stamp has a house A layer of separator and a metal layer containing nanoparticles. The process uses more than 15 parameters for encryption, and similar elements such as company logos can also be added.

3.DNA product barcode. In order to prevent product bar codes from being copied, not long ago, South Korean scientists invented a DNA commodity bar code, which could not be achieved with counterfeiters. The DNA product bar code uses a DNA serial number to form a DNA product bar code and then sprays it onto the product. In order to verify the barcode, a special reader must be used, which also makes the counterfeiters inexperienced. It is reported that during the development of the entire bar code for DNA products, four cutting-edge technologies were involved, but these technologies are absolutely not open, because counterfeiters are also very interested in these technologies. Scientists predict that once DNA product bar codes are promoted, they will greatly increase people’s trust in products.
