Cigarette packaging laser holographic transparent film

Laser holographic packaging machine 'target=_blank> transparent film is often made using two methods. One is to use the “demetallization technology” to etch the aluminized layer on the back of the laser holographic aluminizing film into high-resolution metal dots (similar to the screen dots in modern printing platemaking), also known as “mesh”. "Tune" or "screen method." After the metallization treatment, the metal holograms still function as reflection holograms, and where no metal dot is transparent, the line of sight can be seen through the holographic film below the graphics. Therefore, this technology is English translation for "see through". A typical example of a holographic packaging machine using a demetallization technology'target=_blank>transparent film is a holographic packaging machine'target=_blank>transparent film for a Chinese resident identity card.

Another method for making a holographic packaging machine'target=_blank>transparent film is to successively evaporate a higher refractive index transparent medium film on one side of the plastic film molded hologram, and make the hologram reproduction angle equal to exactly two kinds of media. The total reflection angle. Since the plastic film and the dielectric film are all transparent, this is a truly "transparent" laser holographic film. In addition, the reproduction of the hologram skillfully uses the total reflection generated when the light enters the photoclear medium from the optically dense medium, and thus the reproduced hologram is still brilliant and bright.

Laser holographic packaging machine' target = _blank> transparent film can be used directly as cigarette packaging material, can also be made into holographic cable. At present, shrinking packaging tends to be popular on the market, accounting for more than 50% of external packaging. The shrink wrap and the material of the laser holographic package are the same, and the heat shrinkable plastic film can be combined with a special macromolecule imaging material to form a transparent holographic heat shrinkable packaging material.

Ordinary laser holographic packaging materials need to be composited with whiteboard paper before being color printed thereon. Due to the relatively high cost, cigarette packs generally used for high-end cigarettes, according to rough statistics, domestic 10% of high-end cigarettes have used such packaging materials. Such as Nanjing's "Stone", Yunnan's "Red River" and so on.

The laser holographic aluminized film or laser holographic packaging machine'target=_blank>transparent film is made of transfer type material, which can transfer the coating with holographic pattern to other materials, for example, transfer to paper base material to obtain holographic paper. . Because it is more difficult to directly fabricate a holographic coating on paper, many process difficulties have not yet been solved, so the transfer method is still the main method for manufacturing holographic paper.
