Analysis of Laser Holographic Film Types

【China Packaging Network News】 Anti-counterfeit film is the product of the vicious competition in the market environment. Anti-counterfeit films divided into many kinds, the application of laser holographic film is more extensive, there are four types. 1 , laser holographic film Laser holographic film used in the film is mainly PVC , OPP , BOPP and other plastic film, a variety of laser holographic aluminum, laser holographic transparent polishing film, laser holographic bronzing film, the color of gold, silver, red, green, black Widely used in printing and packaging industry, can be used as a variety of purposes, such as paste paper, carton packaging, clothing, etc., but also for tobacco and alcohol, beverages, food packaging . In giving the packaging security features at the same time, improve the packaging grade. 2 , laser holographic aluminum film (hot stamping film) Integrating the laser holographic electro-deposited aluminum foil and the hot stamping technology, a brilliant laser holographic label and a three-dimensional pattern anti-counterfeit label can be formed on the surface of the printed product. These two kinds of signs can also increase the seal and the back of the anti-cracking, for documents, certificates, bills, trademarks and other security, if the product packaging with this anti-counterfeit labels, the anti-counterfeiting intensity is now a single laser holographic anti-counterfeiting Logo can not match, in addition, according to different user requirements for the production of special laser holographic aluminum film products. Because the special page pattern making includes the business specific requirements, and then into the continuous development of laser holographic technology, whether the special edition of the anti-counterfeiting supply and marketing methods, or its decorative effect is superior. 3 , laser holography plus fluorescent security packaging film Anti-counterfeiting technology of laser holographic and fluorescent anti-counterfeit packaging film combines fluorescent anti-counterfeiting technology and ordinary laser holographic technology organically, which is characterized by that the fluorescent layer is not on the surface of the film but in the interlayer, and the anti-counterfeit film has more security Large, not easy to be copied. And resistant to friction, solvent. Due to the extremely complex process of plate making and batch processing, the packaging film must have expensive lasers, lithography boards, molding machines, coating machines, slitting machines, coating machines and the like. The preparation of such packaging materials involves optical, chemical, Cryptography, physics and informatics and other multidisciplinary techniques, it is difficult to imitate. Laser holography plus fluorescent anti-counterfeiting includes two forms, one is anodized aluminum, the other is a thin film, the latter is based on user needs printed colorless fluorescent security text or pattern of transparent film, in natural light can not see traces , But in the UV light can see a clear fluorescent security text or graphics. 4 , flexible laser holographic anti-counterfeit film Flexible laser holographic anti-counterfeiting film, including organic film base, reflective layer, anti-counterfeit labels layer. The structure is characterized in that: the reflective layer is coated on the film layer, which is a layer of highly refractive index organic resin, and the anti-counterfeit label is printed on the organic resin reflective layer to form a laser holographic patterned grating. Film base material can choose BOPP , PET , PE . Organic resin reflective layer is the use of a single layer of high refractive index of polyurethane resin, polyphenylene resin and amino resin. A practical flexible transparent laser holographic anti-counterfeit film can be made by coating a layer of organic resin reflective layer on the film base layer and then printing a laser holographic image layer on the organic resin reflective layer.
