Anti-counterfeiting packaging commonly method
Seven kinds of anti-counterfeiting packaging commonly used method.
Hologram is the role of two coherent light beam interference pattern resulting from the record results. In which a beam of light through the interference pattern or interferogram reflection, and therefore can not record. This technology can record the human visual or other optical instruments all the necessary information, that information can be generated by the three-dimensional objects in real images, is the most common relief hologram hologram. The future as we are familiar with the three-dimensional art form, and other valuable information on the product label or the safety of anti-counterfeit labels.
2 Other optical instruments
Other anti-counterfeiting technology, including variable optical variable optical diffraction techniques, thin film, retroreflective materials and quantization coding images. Optical film is characterized by variable, variable film is tilted, the color change with it. The use of semi-transparent retroreflective material film layers, which have security identification code. Security code is only visible under light in character. Quantization coding image printing, to use a unique program of electronic camera, quantization coding, deformation, overlay images, printed on the image so that only be interpreted by a special decoder.
3 smart card
"Smart card" is a series can be readers in general. There is a small silicon chip on the card and a set of electrical contact points, can read the stored data. The size and shape of the smart card and quite general, but you can access a smaller format. The technology allows the storage and retrieval or drill text, images, digital sound, etc., similar to Chi to read the floppy data.
4 magnetic
Magnetic bar codes are widely used in plastic card and paper cards, such as tickets and is a simple and easy to carry pocket-sized data storage methods. Magnetic stripe data is stored in a set of encoded magnetic particles, a large amount of information storage, information can be read by touch scanner.
In contact with the memory card, magnetic stripe card to be replaced once every 2-3 years. The main problem is to use their card more easily replicated, so the anti-counterfeiting technology in the field of product safety in the application of certain limits.
5 bio-coding
Breakthroughs in biotechnology to promote people's awareness of the uniqueness of biological proteins such as antibodies, enzymes and DNA (DNA). Protein-specific biological characteristics of the chemical structure and reactivity of identification, making anti-counterfeiting technology in the biotechnology becomes an increasingly important area.
Antibody is extremely sensitive, is to provide product information specific method. Antibodies are the immune system of biological macromolecules, to identify and capture the micro-chemical characteristics.
6 ink
Inks and surface coatings is a white liquid body particles and liquid resin binder blend, and the Senate combined with additives to control the flow of ink and surface coating and other relevant characteristics. When someone attempts to change or eliminate print, the ink will react to it as a security tool for instrument testing, in order to determine the authenticity of the printing.
7 micro-card
Initially identified as a micro card in order to trace explosives in development or production. Explosives within the micro card to join, can be determined.
Micro card in the form of irregular and random, some micro-level of the small plastic particles, and are not easily broken. Card on behalf of their particular color sequence encoding card, micro card number may encode as many as 45 million. Micro-cards can be used on products and packaging, and use diverse, such as micro-smooth surface of the card is placed in one of the methods.
