Laser holographic transfer paper technology and market

Laser holographic transfer paper, also known as laser cardboard. It transfers the traditional laser holographic characters and patterns that can only be recorded on plastic films, transferring them to the paper required for printing without reservation, changing the original laser holographic carrier, and becoming a new source of anti-counterfeiting packaging materials. There are two types of laser jam production methods. One is the direct coating method. The so-called direct coating method is a method of directly applying a laser hologram to a paper. The production process is relatively simple, but the product has great limitations, namely, it is only suitable for the lighter weight, and there are special requirements for paper quality; the second is the transfer method, the so-called transfer method is the first laser Holographic coating on the PET film, and then through the composite, peeling process, the holographic layer to the user's paper production methods. Its advantages are: 1 can be transferred to about any thickness of the concrete; 2 can make full use of the flatness of the PET film, so that the paper surface holographic gloss more bright. The disadvantage is that the process is relatively complicated. Laser paper sheets made by transfer methods are generally called laser hologram transfer papers. The following describes the technology, features and market of laser holographic transfer paper.
First, the laser holographic transfer paper technology Laser holographic transfer paper is a comprehensive use of laser holographic molding, computer lithography, special plate making, precision electroforming, fine chemicals, high-precision peeling and other science and technology of a variety of science and technology products. Among them, the most critical technologies are laser holographic plate making, laser holographic layer fabrication, and the preparation of a release layer.
1. The basic process flow of laser holographic transfer paper production. PET film → peeling layer → coating holographic layer → holographic stamping → vacuum aluminum plating → composite with paper → PET film and paper peeling → roll opening → inspection packaging 2. Laser hologram plate making. Laser hologram plate making mainly consists of three parts. The first is that holographic photographing uses the interference principle of a laser beam to form an embossed holographic image on a recording medium. This is followed by computer lithography. The already designed pattern is processed by computer-specific software and then lithographically processed by a laser under the control of a computer. Once again electroforming, the pattern of relief text remaining on the photoresist plate after holographic photographing and computer lithography was passed through precision electroforming to make a nickel plate with high diffraction efficiency, good resolution, and a large viewing angle.
3. Laser holographic layer production. The requirements for the holographic layer of the laser hologram transfer paper are uniform, flat, and high in transparency. At the same time, it is required that the holographic layer and the peeling layer can be firmly combined, otherwise the mechanical strength of the transfer paper will tear the peeling layer and the holographic layer during the stretching process. The holographic layer is also suitable for vacuum aluminum plating to avoid the problem of loss of holographic information during the aluminum plating process. Therefore, the above factors should be fully taken into consideration when selecting the formula, and the mixture ratio of several maple trees is used.
4. Preparation of peeling layer. The peeling layer is also called release layer. Before the holographic transfer paper is used as a packaging product, it is generally printed. Therefore, it is required that the peeling layer should not only be completely peelable with the substrate, but also be combined with the printing ink, and the coating should be very thin, and has a rather superior Transparency and a certain degree of mechanical strength, generally should use organic resin to prepare the peeling layer.
Second, the characteristics of laser holographic paper and the market 1. Laser holographic transfer features. 1 security features. Laser holographic transfer paper as a packaging paper, the entire surface of the paper with holographic anti-counterfeit text and patterns, this advantage is the use of logo anti-counterfeiting and security line security can not be compared. At the same time, it must not be involved in the field of science and technology, the process is complex, and the technical content is high, which greatly increases the difficulty of counterfeiting. Under normal circumstances, few counterfeiters can copy it; Laser holographic transfer paper does not affect the printing of its surface, and it can be perfectly combined with printing inks to contrast each other and improve the overall decorative effect of packaging; 3 environmental protection function. The barrier property of laser holographic transfer paper is similar to that of aluminum foil paper, but it is different from ordinary laminated paperboard paper of aluminum foil composite paper. It can pollute the environment because it cannot be degraded. Its physical properties are exactly the same as ordinary paper, and it can be recycled and degraded without polluting the environment. This is in line with EU requirements for packaging materials. If China's cigarettes want to enter the European market, we must first solve the problem of packaging materials; 4 identification is simple. The laser holographic text pattern of laser holographic transfer paper is dazzling. Clear and readable under point light source, easy for ordinary consumers to identify and identify; 5 Reasonable price. The current price positioning of laser holographic transfer paper is slightly higher than that of ordinary aluminum-sprayed aluminum and aluminum paperboard, which is much lower than that of imported similar products. Businesses can accept.
2. The market for laser holographic transfer paper. Laser holographic transfer paper is mainly used for anti-counterfeit packaging of various famous wines, medium and high-grade drugs and foods. In cigarette products, it is mainly used for lining paper and outer packaging boxes. In alcoholic products, it is mainly used for bottle labeling wine and wine packaging boxes, and the use of laser holographic transfer paper as packaging will gradually become the preferred choice of packaging materials for famous brands.
Shenzhen Jinwei Special Beer has been using imported laser holographic transfer paper as a wine label for several years and has not been found to have been counterfeited. Liqun new long-shouldered cigarettes use laser holographic transfer paper as a packaging box. Since the brand was put on the market, its overall decorative effect and anti-counterfeit effect like the elegant and precious brocade stencil have been praised by consumers.
Shaoxing Jinghua Laser Products Co., Ltd. was the first company in China to successfully develop laser holographic transfer papers. Its products passed the provincial and ministerial level appraisal not long ago. Experts from the anti-counterfeit packaging industry agreed that laser holographic transfer paper integrates anti-counterfeiting, environmental protection and decoration into one, and has opened up new sources of materials for the anti-counterfeit packaging printing industry. The key technologies of the product, such as holographic layer and peeling layer, are original and the integrated technology of the product has reached the domestic leading level, filling the domestic gap. The product was used by users such as Hangzhou Cigarette Factory and reflected it well. (Wen Shaobo)
