Introduction Special Paper

Among the various anti-counterfeiting technologies currently used, such as digital anti-counterfeiting, ink anti-counterfeiting, and optical anti-counterfeiting, paper anti-counterfeiting methods are relatively simple and applicable, and are gradually favored by many manufacturers, providing a broad market for anti-counterfeit paper products.

No film holographic dark security paper. Quantitative can be divided into 50 ~ 350g/m2, no film, easy to degrade, anti-counterfeiting design using implicit design, the surface gloss of the paper exceeds aluminum foil, PET, polyester aluminum film mirror paper, printing adaptability, coating Layers and patterns of acid, alkali, gasoline, alcohol resistant wipe, scrap rate and printing is much less difficult than aluminum foil and mirror paper.

Magnetic security paper. There are obvious magnetic patterns in the paper, and the magnetic material powder is added into the pulp. When the pulp and magnetic powder are embedded in the magnetic security paper according to the shape of the magnetic plate pattern, the magnetic powder should pass through a 200 mesh screen and should be dyed.

Superionic media specialty paper. The paper is a fourth-generation anti-counterfeiting product that utilizes a large-scale heavy ion accelerator, a state-controlled nuclear physical equipment, and integrates the ion micropore technology with the papermaking process. Because the heavy ion accelerator is controlled by the state, all other equipment cannot To achieve its anti-counterfeiting technical indicators, so fundamentally eliminate the falsification.

Texture paper. The colored pulp is thrown into the white pulp, which causes the visible texture of the texture to be visible to the naked eye. The texture is then printed into a security label. The texture image of the label is stored in a special computer anti-counterfeiting system database. After the label, the customer can access the database through the telephone, fax machine or the Internet to check the physical texture of the label and identify the authenticity of the product.

Add fluorescent fiber paper. The fluorescent material is dyed on a chemical fiber carrier, and the fluorescent fiber is made into a fluorescent fiber paper according to a certain ratio. The surface is the same as plain paper, but as long as the ultraviolet lamp on the counterfeit lamp shines, the fluorescence added to the paper is increased. Fibers immediately appear blue, and this technique is used more often in the production of stamp paper.

Laser printing security special paper. Special anti-counterfeiting properties are provided by coating with a color-enhancing adhesive. This special coated paper ornament adds a color-enhancing pattern and is dissolved in paper after being printed by laser, and will not disappear due to friction, scratch, or the like.

Thermal security paper. This kind of anti-counterfeiting paper does not need to rely on special instruments and equipment. It can identify authenticity only by the way of finger touch, mainly in the paper is embedded with a security filament called “Thermotext”. This kind of filament uses thermal discoloration or thermal ink. Masking text or patterns, when the temperature is high, the text or pattern appears when the masking fails, and it recovers when it cools.

Watermarked paper. The non-aqueous liquid composition containing the thermosetting resin and the heating agent is contacted with a certain size solution and aged to make the watermark or pattern portion of the sheet less opaque than the other portions. This is a commonly used anti-counterfeiting technology in banknote paper.

Color fiber security paper. This kind of paper processing method is more convenient than the use of watermark roll, use a variety of colorful fiber filaments, generally two or more colors, fiber is cotton, hemp, natural fiber or polypropylene, acrylic and other chemical fiber, cut into 4 ~ 8cm, in the adjustment Add it in the box. Because the production process is relatively simple, the technology is currently used more, such as banknotes, brand-name cigarette packaging.
