The application provides an anti-fake film material and a manufacturing method thereof, and the manufacturing method comprises the following steps: selecting a base material, manufacturing a metal foil with a micro-nano diffraction grating structure on the base material, crushing the base material and the metal foil to form particles, high-temperature melting the particles formed by crushing the base material and the metal foil, forming free metal micro-foils after melting the metal foil, and forming the anti-fake film material after extruding and calendering the base material and the metal foil after high-temperature melting. The metal foil has the micro-nano diffraction grating structure, which helps to improve the anti-fake effect of the metal micro-foil, so that the anti-fake film material has a certain anti-fake effect, and the difficulty of imitation and forgery by illegal persons is increased. Meanwhile, the anti-fake film material with the metal foil can be applied to various fields and various types of anti-fake products, can be superimposed with other anti-fake technologies in the products, the anti-fake effect of the products is increased, and the anti-fake film material has the characteristics of wide application range and difficulty in forgery.
