Bags, etc., can also provide various types of flexible packaging market, such as food flexible packaging or hose packaging. Transparent PET laser holographic films can be made into molded packages. At the same time, PET laser holographic film is also often used for printing into self-adhesive labeling, or into silver, silver, powder, etc.

OPP laser holographic film

Generally speaking, 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 printing suitability of OPP laser holographic films has made great progress, and customers can easily achieve exquisite printing. The transparent OPP laser holographic film is also a good glazing material, which can bring a completely different feeling to the printed matter. In addition, OPP laser holographic film is also an ideal material for flexible packaging.

PVC laser holographic film

Although the use of PVC is limited in European and American countries with strong environmental awareness, but because of its ideal printability, there are still quite a few applications in printed matter. PVC laser holographic film is more often made into various Christmas ornaments, spring couplets, greeting cards, etc. Passionate Latin American nations also use a lot at carnivals. The dazzling laser holographic gloss can add a festive atmosphere, so it also Very popular with consumers.

Laser holographic washing film

Laser holographic washing film is made of PET laser holographic film, OPP laser holographic film and PVC laser holographic film. The so-called water-washed film is the use of sodium hydroxide to remove the anodized aluminum on the surface of the film, so that in addition to the laser holographic gloss, the film surface also displays a unique through-air pattern or specific trademarks, graphics and so on. After being made into cartons, bags, book covers, etc., it is not only beautiful, but also has anti-counterfeiting effects. It is mainly suitable for brand packaging.

In addition to laser holographic films, there are currently other laser holographic materials.

Laser holographic paper.

Can be divided into two kinds of film stickers and pure paper. Film stickers are made of laser holographic PET or OPP films bonded to different types of paper. The bonded cardboard is not only more stiff, not easy to tear, but also waterproof. Laser holographic pure paper directly prints the laser hologram on the paper through advanced embossing technology.
