Packaging anti-counterfeiting material use

Packaging Anti-counterfeit printing materials vary, but mainly paper and ink, and they have special requirements.
Anti-counterfeiting paper uses various anti-counterfeiting technologies to make various anti-counterfeiting papers in the papermaking process. It is used to print packaging labels or packaging papers to achieve anti-counterfeiting. At present, there are mainly the following paper anti-counterfeiting technologies.
1. Laser holographic technology uses laser holography technology to directly make laser holographic patterns on paper to make laser hologram security paper.
2, watermark technology This technology is in the process of paper web forming, when the paper sheet just interweave still contains a certain amount of water, the use of a watermark with an engraved texture rolling embossed paper surface, making the wet paper page part of the organization formed a shift Different fiber densities, a variety of graphics, digital or text watermarks with light and dark textures.
Some companies also filed their own special watermark patterns with specific management departments. At the same time, papermaking companies no longer manufacture the same special-purpose paper for other users. Although this has increased the cost of paper, it has also greatly increased the cost of the paper. Its anti-counterfeiting effect is ideal.
3, special additives technology (1) add color fiber filaments. Color fiber filaments are colored fibers that are distributed on the paper surface and have different colors from the paper. The color, length, thickness, degree of exposure and distribution of the fibers are somewhat different.
(2) Adding Security Lines Security lines refer to embedding, in whole or in part, opaque strips of metal or plastic tape in paper, often with transparent or holographic microtext information, magnetic information, etc. The production of security lines requires high papermaking technologies and complicated processes, especially the security of open windows (intermittently exposed). This kind of security thread is buried in the paper for a period of time, and is exposed on the surface of the paper. Forging is quite difficult. In recent years, it has also introduced a heat-sensitive security cord that is pink at room temperature and opaque. As long as the temperature is raised to 37~C with a finger, localized microtext will appear.
(3) Adding fluorescent fibers A colorless fluorescent fiber strip was added to the pulp in a ratio during the papermaking process. The paper can display fluorescent fiber strips under ultraviolet excitation, which can serve as a public identification function.
(4) Adding Trace Additives Using the principle that organisms have an anti-body-specific response, a very small amount of anti-elements is added to a certain part of pulp or paper. When detecting, it is combined with the corresponding specific antibody, and the presence or absence of the reaction of the marker, fluorescence, etc. is used to distinguish the authenticity from the others.
4, chemical technology In the pulp or in the paper surface sizing add special compounds, made of chemical encryption paper, this paper when coated with specific chemical reagents can develop color or show fluorescence.
5, special equipment technology Use of special equipment when papermaking, such as special anti-counterfeit paper ion media, rely on the state-controlled large-scale heavy ion accelerator, the ion micro-hole technology and papermaking technology into a system of special ionochemical media security paper. Also for example, the use of laser anti-counterfeiting technology and special equipment combined with paper can be made of laser anti-counterfeiting paper.
