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-counterfeiting paper products.
Non-film holographic dark anti-counterfeiting paper. The basis weight can be divided into 50-350g/m2, no film, easily degraded, and the anti-counterfeiting pattern adopts implicit design. The surface gloss of the paper exceeds that of aluminum foil paper, PET, polyester polyaluminum film mirror paper, good printing adaptability, and coating And the pattern is resistant to acid and alkali, gasoline and alcohol, and the waste rate and printing difficulty are much lower than that of aluminum foil paper and mirror paper.
Magnetic anti-counterfeiting paper. There are obvious magnetic patterns in the finished paper, and magnetic material powder is added to the pulp. When the pulp and magnetic powder are implanted in the magnetic anti-counterfeiting paper in the shape of the magnetic plate pattern, the magnetic powder should pass through a 200-mesh sieve and should be dyed.
Super-ion medium special paper. The paper is a fourth-generation anti-counterfeiting product that uses a large-scale heavy ion accelerator for nuclear physics equipment that is exclusively controlled by the state, and integrates ion microporous technology with papermaking technology. Because the heavy ion accelerator is exclusively controlled by the state, no other instruments and equipment can It reaches its anti-counterfeiting technical indicators, so fraud is fundamentally eliminated.

Basic knowledge of paper industry 2021.01.11
1. What are the raw materials of modern papermaking? Answer: The raw materials of modern papermaking include plant fibers (wood, bamboo, grass, etc.), mineral fibers (asbestos, glass fiber, etc.), other fibers (nylon, metal wire, etc.), and polymer materials obtained by cracking petroleum. At present, the paper used for writing, printing and packaging is still mainly made of plant fibers. 2. What are the types of plant fiber raw materials for papermaking? Answer: At present, the plant fiber raw materials used in the paper industry can be divided into two categories: Wood fiber raw materials: plant fibers obtained directly from trees. Non-wood fiber raw materials: divided into grass fiber raw materials, bast fiber materials and seed hair fiber materials. 3. What are the composition and functions of commonly used auxiliary materials for paper? Answer: Auxiliary materials refer to various additives added to paper to meet the different performance of paper. The auxiliary materials are composed of fillers, rubber materials, pigments and other chemical additives. Fillers can improve the smoothness and opacity of paper; sizing materials can make paper have water resistance; pigments can increase the whiteness of paper; dyes can color paper; other chemical additives can change the properties of paper to provide Some special uses of paper. 4. What is the role of rubber? Answer: Paper produced from plant fibers can absorb water or other liquids because of the large number of pores between the fibers themselves and the fibers, and the cellulose and hemicellulose that make up the fibers contain a large amount of hydrophilic hydroxyl groups. In order to prevent the paper from being infiltrated by water or other liquids, it is necessary to add liquid-resistant colloidal substances or film-forming substances, that is, sizing materials, to the paper to provide the paper with resistance to liquid penetration and diffusion. The process of applying size in the paper industry is called sizing. 5. What are the methods of sizing? Answer: According to different sizing effects, sizing methods are divided into internal sizing and surface sizing. Internal sizing is to add sizing material into paper pulp, and then make it into liquid-repellent paper and cardboard. Commonly used rubbers include rosin rubber and synthetic rubber. Surface sizing is to coat a thin layer of sizing material on the surface of the paper to make the paper hydrophobic. Commonly used rubbers include starch, animal glue, and synthetic rubber. Surface sizing is mainly used for offset paper, writing paper, and packaging paper and cardboard that require liquid repellency. 6. What are the effects of surface sizing on the performance of printing paper? Answer: ①Increase the water resistance and surface strength of the paper, which can reduce the lint of the paper in offset printing; ②Improve the printability. If the surface sizing material is too small, the paper will absorb too much binder in the ink during printing, resulting in The blot is dull. On the contrary, if the surface sizing material is too much, it will slow down the drying rate of the ink, resulting in smearing and bright stains; ③Increase the erasability of the paper, surface sizing can reduce the penetration of ink, so it is easy to wipe off the ink and increase The abrasion resistance of the paper surface; ④Increase the strength of the paper, such as bursting resistance, folding resistance and tensile strength; ⑤Reduce the difference and deformation of the paper. 7. What is the role of filler? Answer: The filler is used to make the paper obtain specific properties, such as whiteness, opacity, smoothness, etc. At the same time, the addition of fillers makes the internal voids of the paper smaller and finer, thereby increasing the ink absorption of the paper and making the ink absorption change uniform. Usually added to the water-insoluble or slightly water-soluble minerals in the slurry, the content in the printing paper is about 10%-25%, and the amount of addition of different papers is different, and may vary greatly 8. What are the characteristics of printing paper fillers? Answer: The filler for printing paper should have high whiteness, high refractive index, fine particles, low water solubility, low density and good chemical stability. In addition, it is best to have abundant resources and low price. 9. What are the commonly used fillers for printing paper? Answer: The most commonly used inorganic fillers are talc, clay, titanium dioxide and calcium carbonate. Among them, titanium dioxide is an expensive and high-quality filler; organic synthetic fillers are some polymer substances. 10. What are the effects of fillers on the performance of printing paper? Answer: Adding fillers to printing paper can improve the printability of the paper, such as increasing the whiteness, smoothness, opacity and stiffness of the paper. Improve the affinity, softness and stability of paper to ink, thereby contribu
