In the current digital anti-counterfeiting, ink anti-counterfeiting, optical anti-counterfeiting and other anti-counterfeiting technologies, the paper anti-counterfeiting method is relatively simple and applicable, and gradually favored by many manufacturers, providing a broad market for anti-counterfeiting paper products.
No film holographic dark anti-counterfeiting paper. The paper can be divided into 50-350g / m2, no film, easy degradation, anti-counterfeiting pattern using implicit design. The surface gloss of the paper is higher than that of aluminum foil paper, pet, polyester polyaluminum film mirror paper, good printing adaptability, acid and alkali resistance, gasoline resistance and alcohol resistance of coating and pattern, and the rejection rate and printing difficulty are much lower than that of aluminum foil paper and mirror paper.
Magnetic security paper. There are obvious magnetic patterns in the finished paper. Magnetic material powder is added into the pulp. When the pulp and magnetic powder are implanted into the magnetic anti-counterfeiting paper according to the shape of the magnetic plate pattern, the magnetic powder should pass through 200 mesh sieve and be dyed.
Super ion medium special paper. The paper is the fourth generation of anti-counterfeiting product, which integrates the ion micropore technology and papermaking technology by using the large heavy ion accelerator specially controlled by the state. Because the heavy ion accelerator is specially controlled by the state, and any other instrument and equipment can not meet its anti-counterfeiting technical index, so the counterfeiting is fundamentally eliminated.
Textured paper. The white pulp is sprinkled with colored fiber to make the texture paper visible to the naked eye with clear texture pattern, and then printed into an anti-counterfeiting label, and the texture image of the label is stored in a special computer anti-counterfeiting system database. After the product is pasted with the label, customers can enter the database through the telephone, fax machine or Internet to check the real texture of the label and identify the authenticity of the goods.
Add fluorescent fiber paper. The fluorescent material is dyed on the chemical fiber carrier, and the fluorescent fiber is made into fluorescent fiber paper according to a certain proportion. The surface of the paper is the same as that of ordinary paper, but as long as the purple light on the counterfeit identification lamp shines, the fluorescent fiber added into the paper immediately turns blue. This technology is widely used in the production of stamp paper.
Laser printing anti-counterfeiting special paper. It is endowed with anti-counterfeiting performance by coating with special color increasing adhesive. This kind of special coated paper decorated with color increasing pattern will dissolve in the paper after laser printing, and will not disappear due to friction, scratch, etc.
Thermal security paper. This kind of anti-counterfeiting paper can identify the authenticity only by finger touch without the help of special instruments and equipment. The main reason is that the anti-counterfeiting filament named "thermotext" is implanted in the paper. This filament uses thermochromic or thermal ink to mask the text or pattern. When the temperature is high, the masking failure will result in the text or pattern, and after cooling, it will recover as before.
Paper with a watermark. The non-aqueous liquid compound containing thermosetting resin and thermochemical agent is contacted with a certain glue solution and cured to make the watermark or pattern part of the paper more opaque than other parts. This is a common anti-counterfeiting technology in banknote paper. Color fiber security paper. This paper processing method is more convenient than the use of watermark roller, choose a variety of brightly colored fiber, color generally more than two kinds, fiber for cotton, hemp, natural fiber or polypropylene, acrylic and other chemical fiber, cut into 4 ~ 8cm, in the adjustment pulp box can be added. Because the production process is relatively simple, the technology is widely used at present, such as banknotes, famous brands, all kinds of cigarette packaging, etc.
