The invention belongs to the technical field of packaging materials and particularly relates to a multiple metal color anti-counterfeiting aluminum foil sealing gasket and a preparation method thereof. The multiple metal color anti-counterfeiting aluminum foil sealing gasket is formed by sequentially connecting a mold imaging layer, a color printing layer, a holographic information layer, an aluminizing layer, a medium layer, an induction layer, an EVA adhesive layer and a sealing layer from outside to inside. The preparation method comprises the steps of mold imaging layer coating, designing, gravure mold pressing, aluminizing, composite transferring and sealing layer compositing, so that the sealing gasket is obtained. A gravure and mold pressing integrated method is adopted so that a multiple metal color holographic graphic anti-counterfeiting technology is realized on a same layer, and the visual impact and the anti-counterfeiting intensity are enhanced; a consumer can check and distinguish the sealing gasket easily, all anti-counterfeiting characteristics can be implemented and checked, a site inspection function can be realized, and simultaneously the unfulfillable non-transferability of an anti-counterfeiting mark is realized; an environment-friendly material is composited for manufacturing the anti-counterfeiting aluminum foil sealing gasket, so that the environment protection function is improved.
