Anti-counterfeiting technology on medical packaging

by:Leadtech Coding     2021-07-29
Ink anti-counterfeiting technology is currently a widely used anti-counterfeiting technology in the pharmaceutical packaging industry. This kind of anti-counterfeiting technology is mainly used to add special substances to ordinary ink binders, which are processed into special printing inks through special processes. This type of anti-counterfeiting technology is characterized by simple implementation, low cost, good concealment, bright colors, and convenient inspection. At present, anti-counterfeiting inks mainly include ultraviolet-activated fluorescent anti-counterfeiting inks, magnetic anti-counterfeiting inks, heat-sensitive color-changing anti-counterfeiting inks, daylight-induced color-changing anti-counterfeiting inks, optically variable anti-counterfeiting inks, pressure-sensitive anti-counterfeiting inks, infrared anti-counterfeiting inks, anti-modification anti-counterfeiting inks, anti-counterfeiting inks, etc. . Ink printing anti-counterfeiting is an important part of medical packaging anti-counterfeiting technology. Experiments show that the fluorescent anti-counterfeiting ink with fluorescent pigments has good water resistance, acid resistance, and alcohol resistance. At present, it is widely used in medical packaging, especially blister packaging. It is also often used in other pharmaceutical packaging, such as flexible pharmaceutical packaging and pharmaceutical labeling. It can be said that fluorescent anti-counterfeiting ink is currently the most widely used anti-counterfeiting ink in the anti-counterfeiting of medical packaging inks. The fluorescent ink is made by adding the corresponding visible fluorescent compound to the ink. Its anti-counterfeiting feature is that the printed matter can emit glittering fluorescence under the action of visible light and ultraviolet light. Different formulations can get different fluorescent inks. For example, by adding ultraviolet-excited visible fluorescent compounds (such as tristyrene derivatives, stilbene derivatives, tetrastyrene derivatives, etc.) into the ink to obtain ultraviolet fluorescent inks, which can emit red, yellow, green, Visible light such as blue. The infrared fluorescent ink can be obtained by adding visible fluorescent compound with infrared excitation to the ink, which can emit green visible light under the irradiation of the far-infrared lamp.
