Cigarette bag anti-counterfeiting profile Compared with the anti-counterfeiting technology applied in general products, cigarette packs have higher requirements for anti-counterfeiting technology. From the application perspective, cigarette manufacturing companies, on the one hand, incorporate substances with anti-counterfeiting properties in the production process of packaging materials, and on the other hand use anti-counterfeiting printing technology during the printing process. Laser holography and ink security are the most commonly used anti-counterfeiting technologies. The holographic products used for cigarette packets mainly include laser holographic anti-counterfeit labels, laser holographic packaging materials, and laser holographic hot stamping materials.
The use of holograms not only enhances brand awareness and customer reputation, but also creates an attractive, eye-catching package. At present, the main types of laser holograms used in cigarette packaging are: disposable holographic anti-counterfeit labels, holographic anti-counterfeit cable, holographic hot stamping, transparent holographic film, holographic anti-counterfeiting heat shrinkable film, holographic transfer paper, and the like. In addition, the integrated design of three-dimensional holographic technology and two-dimensional printing technology for cigarette packaging and printing will also be a trend in the development of cigarette packaging.
Laser holographic anti-counterfeit labels China's laser holographic anti-counterfeit labels are mostly based on laser holograms, incorporating dynamic holographic technology, multi-channel (isotopic) technology, 2D/3D technology, dot matrix holographic technology, actinic relief technology, and micro encryption Various anti-counterfeiting technologies, such as technology and machine identification technologies, and comprehensive anti-counterfeit labels have passed the results appraisal hosted by the State Administration of Tobacco Control in 1997. In recent years, China has made new achievements in the aspects of encryption of hidden information, anti-copy technology, transparent laser holography, laser holographic hot stamping, laser holography and digital anti-counterfeiting technology.
Special emphasis should be placed on the use of laser holographic anti-counterfeit labels on cigarette packages (including bags and packets) must have a "one-time use" feature, that is, holographic anti-counterfeit labels stuck on cigarette packaging, tear off You should not be able to use it repeatedly (named tamper-evedent abroad). As the cigarette packaging material is a non-polar polymer film, the general holographic anti-counterfeiting label material and commonly used adhesives may meet the "one-time use" requirement. Must use a one-time holographic anti-counterfeiting label that is specially designed for cigarette packaging and contains a special "anti-glare" to meet "one-time use requirements."
Laser holographic packaging material Laser holographic packaging material has a strong visual impact effect, can make the product packaging colorful, and has a strong anti-counterfeiting effect, has become a much respected packaging materials for businesses, is rapidly being applied to a variety of commodity packaging on. Laser holographic packaging materials for cigarette packs usually include laser holographic aluminum film, laser holographic packaging machine, 'target=_blank', transparent film, laser holographic paper, laser hologram wire, and the like.
1. Laser holographic aluminized film Laser holographic aluminized film is a kind of laser holographic reflecting film. Laser holographic aluminized film manufactured by high-resolution dot matrix lithography technology has a dynamic combination effect of changing magic. At the same time, integrated encryption and anti-counterfeiting technology (such as photo-relief technology) can also be adopted on it to make it have an excellent anti-counterfeit function. The actinic relief technology is a fusion of non-holographic technology and holographic technology. The technology can make any pattern or text on the background of holograms. Its color does not change with the observation color, and the unique information contained therein is identified by a laser pen or special instruments.
2, laser holographic packaging machine 'target = _blank> transparent film laser holographic packaging machine' target = _blank> transparent film often uses two methods to produce. 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 “meshâ€. "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.
The new highlight of cigarette packaging security packaging printing - the combination of three-dimensional hologram and color printing combines the rich color effects and printing flexibility of inks with the powerful visual appeal of holograms, and integrates holographic technology and printing technology. The control of the colors produced will produce some very peculiar effects. It is incomparable to a single hologram and becomes an extremely effective means in marketing, security, and product promotion. The combination of holography and printing is used on the packaging box of cigarettes. It is an imaginative and attractive development project. It is also a development trend in the modern packaging and printing industry.
There are three ways to add ink to a hologram. The simplest method is to print on a stencil hologram. Alignment between the hologram and the ink image is not required, and the production cost is the lowest. This method is used on Colgate toothpaste boxes and domestic "Diamond" toothpaste boxes. Another method is that the printing has a certain spatial relationship with the hologram, and the effect is compensated by using ink on the hologram or around the hologram; although it is more difficult than the printing on a stenciled background hologram, the effect is produced. it is good. The third method is that printing and holograms need strict alignment. This technology is the most difficult, but it can provide designers with the greatest creative space and a high degree of flexibility, and the strongest artistic charm.
The relevant enterprises in China have carried out a series of research and development work on the combination of holography and printing for tobacco package security, including:
1) Technical measures for packaging design and prepress processing;
2) In the proofing test, the design effect is controlled by adding ink;
3) For different printing technologies, how to give full play to the characteristics of holographic and avoid some of the problems that occur;
4) Solve the difficulties in the alignment of printing and holograms, transparency processing during printing, holographic effect protection in the printing process and other technical and technological difficulties.
The cigarette packaging printing technology, which can prevent counterfeiting and attract customers' attention, has a very strong competitiveness. The use of printed holograms for the overall design of cigarette packaging should be a very perfect solution. As long as holographic manufacturers work closely with cigarette production and packaging printers, this solution can be realized in the holographic packaging and printing of cigarette packets, which will add brilliance to China's thriving tobacco packaging and printing industry.
