The invention belongs to the field of anti-counterfeiting techniques of materials, in particular to a digital holographic anti-counterfeiting bottle cap and a production method thereof. The digital holographic anti-counterfeiting bottle cap comprises a cap body and anodized aluminum. The anodized aluminum is composed of a base layer, a transfer layer and a gum layer. The transfer layer is composed of a release layer, an information layer and an aluminized layer. The anodized aluminum is printed on the side or top of the cap body by hot stamping. The production method includes: selecting materials, designing, making a plate and die-pressing, aluminizing, printing and partially aluminizing, coating with a printed layer, tagging, applying gum, and performing hot stamping. According to the production method, the holographic printed digital anti-counterfeiting stamping foil is printed to the top and side of the cap body by hot stamping, and holographic printing and digital anti-counterfeiting are integrated.
