At present, laser holographic film image materials mainly have the following types: The most common laser holographic films are polyester film (PET), polypropylene film (OPP), polyvinyl chloride film (PVC) and washed film. Manufacturers can choose different materials according to the application requirements. Different materials have different application scopes.
(1) PET laser holographic film
Because the material is stable, printability is good and meets the requirements of environmental protection, PET laser holographic film is currently the most widely used and most used material. It can be attached to paperboard, printed into various types of packaging, Bags, etc., can also be used in various flexible packaging markets, such as food flexible packaging or hose packaging. Transparent PET laser holographic film can be made into a package. At the same time, PET laser holographic film is often used to print self-adhesive labels, or as a gold thread, powder and so on.
(2) OPP laser holographic film
In general, the printability of OPP is not as good as PET and PVC materials, which makes it very limited in the application of packaging printing. However, by improving the surface treatment technology of OPP materials, the printability of OPP laser holographic film has made great progress, and customers can easily print beautifully. The transparent OPP laser holographic film is also a very good glazing material, which can bring completely different feelings to the print. In addition, OPP laser holographic film is also an ideal material for making flexible packaging.
(3) PVC laser holographic film
Although the use of PVC is limited in environmentally-conscious countries such as Europe and the United States, due to its excellent printability, there are still many applications for printed materials. PVC laser holographic film is often made into various Christmas ornaments, Spring Festival couples, greeting cards, etc. The passionate Latin American people also use a lot at the carnival. The shiny and dazzling laser holographic gloss can also add festive atmosphere to the festival, so it is also Very popular with consumers. Goss International
(4) Laser holographic film
The laser holographic water wash film is made of PET laser holographic film, OPP laser holographic film and PVC laser holographic film. The so-called washed film is the use of sodium hydroxide to remove the electro-aluminum part of the film surface, so that the film surface in addition to laser holographic gloss, while presenting a unique pattern or specific logo, graphics, etc., can be directly used as a wrapping paper, or pasted After being made into a paper box, a bag, a book cover, etc., it is not only beautiful, but also has the effect of anti-counterfeiting. It is mainly applied to brand packaging.
(5) Atomic nuclear confidential laser holographic film
As an anti-counterfeiting technology with high hi-tech content, nuclear track anti-counterfeiting is called “two nuclear weapons†in the field of anti-counterfeiting together with “heavy ion micropore anti-counterfeitingâ€. Nuclear track anti-counterfeiting technology is the use of nuclear reactors and other nuclear materials on the plastic film splinter irradiation, the formation of trace damage in the plastic film, and then through the imaging technology to form a fine logo of the nuclear track micropore anti-counterfeiting patterns required. Finally, after the late commodity processing, a nuclear track micropore anti-counterfeiting label or other forms of nuclear track micropore anti-counterfeiting technology products are obtained. It has the advantages of high technology content, difficult to imitate, easy to identify, low production cost, good communicability with other technologies, etc. It can be said to be a trend to guide today's and future security development. Nuclear track anti-counterfeiting technology products can carry out multiple identification and improve the reliability of ordinary identification. And have first-line, second-line anti-counterfeiting features. Such as the superior performance of the first-line anti-counterfeit identification of polymer nanomaterials VCC - nuclear track anti-counterfeiting, as long as a drop of water or pen, ordinary consumers can easily check the authenticity of goods. At present, it has been widely used in the packaging of famous brands of cigarettes, wines, audio-visual products, books and magazines, and high-end branded products. It is also widely used in passport, card, and ticket security. Combining the nuclear track with laser holography technology, ie, the nuclear track anti-forgery-encrypted image formed on the laser interfering film, can greatly improve the anti-counterfeiting effect of the laser holographic film.
In addition to the laser holographic film, there are currently other laser holographic materials.
