The anti-counterfeiting technology of medicine bottle caps Currently, there are a lot of counterfeit products of medicine bottle caps in the market, which seriously affects the normal development of the medicine bottle cap industry. Therefore, strengthening the anti-counterfeiting marks of medicine bottle caps is increasingly concerned by people. As an interdisciplinary subject, the anti-counterfeiting technology of medicine bottle caps involves many fields. Among them, the ink anti-counterfeiting technology is currently the most widely used anti-counterfeiting technology in the pharmaceutical packaging industry. Its characteristics are: simple implementation, low cost, good concealment, bright color, and convenient inspection. At present, the main anti-counterfeiting inks include ultraviolet-excited fluorescent anti-counterfeiting ink, magnetic anti-counterfeiting ink, thermochromic anti-counterfeiting ink, and sunlight-excited color-changing anti-counterfeiting ink. Meanwhile, after experiments, people found that the fluorescent anti-counterfeiting ink with added fluorescent pigments has good water resistance, acid resistance, and alcohol resistance, and is currently widely used in pharmaceutical packaging, especially in blister packaging. It is also often used in other pharmaceutical packaging such as pharmaceutical flexible packaging and pharmaceutical labels. It can be said that fluorescent anti-counterfeiting ink is currently the most widely used type of anti-counterfeiting ink in pharmaceutical packaging ink anti-counterfeiting. The anti-counterfeiting feature of fluorescent ink is: under visible light and ultraviolet light, the printed matter can emit sparkling fluorescence. This greatly enhances the anti-counterfeiting mark of the medicine bottle cap. Strengthening the anti-counterfeiting mark of medicine bottle caps plays an important role in improving product reputation and customer satisfaction, and is an important guarantee for the sustainable development of enterprises.
