This invention provides an anti-lifting and anti-counterfeiting tape and its manufacturing method. From top to bottom, it comprises a substrate layer, an anti-counterfeiting pattern layer, and a pressure-sensitive adhesive layer with a functional gradient structure. The pressure-sensitive adhesive layer is an integrally molded single-layer structure, and in the thickness direction perpendicular to the plane of the substrate layer, the cohesive strength of the pressure-sensitive adhesive layer exhibits an asymmetric gradient distribution. The pressure-sensitive adhesive layer includes a high-cohesion region: near the anti-counterfeiting pattern layer, the chemical cross-linking density of which keeps the elastic modulus of this region within a preset range, thereby suppressing elastic stringing deformation of the adhesive under peeling force. This invention achieves effective interception and dissipation of the substrate's rebound stress by setting a low-modulus "high-wetting region" on the adhesive side and introducing an "internal stress self-adaptive layer" under the substrate. While ensuring long-lasting adhesion without lifting on curved surfaces, it avoids damage to the cardboard fibers caused by strong peeling, achieving a balance of "strong adhesion without fiber breakage."
