[China Packaging Network News] Anti-counterfeit film is a product that breeds in a vicious market environment. There are many kinds of anti-counterfeiting films. The application range of laser holographic film is more extensive. There are four types of laser holographic film.
1, laser holographic film
The film materials used in laser holographic film are mainly PVC, OPP, BOPP and other plastic films. There are laser holographic aluminized films, laser holographic transparent glazing films, laser holographic bronzing films, etc. The colors are gold, silver, red, green and black. Such as widely used in the printing and packaging industry, can be used for a variety of purposes paste paper, carton packaging, clothing, etc., but also for tobacco and alcohol, beverages, food packaging. In addition to providing anti-counterfeiting features for packaging, the packaging quality has been improved.
2, laser holographic aluminum film (hot stamping film)
Combining the laser holographic aluminum foil with hot stamping technology, it can form colorful laser hologram logos and anti-counterfeit logos on the surface of prints. The two kinds of logos can also be added with seals and back tamper-evident layers for security against documents, cards, tickets, trademarks, etc. If the product is packaged with such a security logo, its anti-counterfeiting efforts are now a single laser holographic anti-counterfeiting. The logo can not be compared, in addition, according to the requirements of different users for the product to create a special version of the laser holographic aluminum film. Because the special pattern design contains the specific requirements of the business, and then integrate into the ever-evolving laser holographic technology, whether it is a special version of the anti-counterfeiting supply and marketing methods, or its decorative effects are superior.
3, laser holographic fluorescent anti-counterfeiting packaging film
The anti-counterfeit technology of the laser hologram plus fluorescent anti-counterfeit packaging film combines the fluorescence anti-counterfeiting technology with the ordinary laser holography technology. The feature is that the fluorescent layer is not on the surface of the film, but in the sandwich layer, and the anti-counterfeiting film has more anti-counterfeiting strength. Large, not easily imitated. And it is resistant to friction and solvents. Due to the plate making of this packaging film, the batch processing process is extremely complicated, and expensive lasers, lithographic plates, mold presses, coaters, slitters, coating machines, etc. must be available, and the preparation of the material involves optics, chemistry, Multidisciplinary techniques such as cryptography, physics, and informatics make it difficult to copy. Laser hologram plus fluorescent anti-counterfeiting includes two forms, one is an electro-aluminum film, and the other is a thin film. The latter is a transparent film that prints colorless fluorescent anti-counterfeiting characters or patterns according to user needs, and does not show traces under natural light. , but clear fluorescent anti-counterfeit text or patterns can be seen under UV light.
4, flexible laser holographic anti-counterfeiting film
The flexible laser holographic security film includes an organic film base layer, a reflective layer, and an anti-counterfeiting label layer. Its structural features are: the reflective layer is coated on the thin film layer, it is a layer of highly difficult refractive index organic resin, anti-counterfeiting mark is printed on the organic resin reflective layer to form a laser holographic grating. Film base material can choose BOPP, PET, PE. The organic resin reflective layer is a polyurethane resin, a polyphenylene resin, and an amino resin that can serve as a single-layer high refractive index. A practical and flexible transparent laser holographic anti-counterfeiting film can be made by coating a layer of organic resin reflective layer on a film base layer and printing a laser holographic image layer on the organic resin reflective layer.
