Fluorescent anti-counterfeiting labels are usually made of organic chemical fluorescent materials or inorganic fluorescent materials. Among them, the anti-counterfeiting label made of organic chemical fluorescent raw materials can keep the actual fluorescent effect for more than 3 years; The anti-counterfeiting label made of inorganic fluorescent materials can keep the actual fluorescent effect for more than 10 years.

Under ultraviolet irradiation, the fluorescent anti-counterfeiting label can indicate or emit all kinds of fluorescence or fading. Organic chemical fluorescent materials are selected, and the actual fluorescent effect of the anti-counterfeiting label can be maintained for at least 3 years or more, while inorganic fluorescent materials are selected, and the actual fluorescent effect of the anti-counterfeiting label can be maintained for 10 years or more.
