The invention discloses a method for manufacturing a shape memory anti-counterfeiting mark, which is characterized by comprising the following steps of: manufacturing a polymer material having a shape memory function into boards of which the surfaces are provided with uneven patterns, wherein appropriate distances should be reserved among the patterns on the board to ensure that the patterns are not superposed with one another in the subsequent calendering process; irradiating and cross-linking the boards; heating the boards of which the surfaces are provided with the uneven patterns after irradiating and cross-linking, and calendering the boards into thin films by using a three-roll calender to ensure that the boards of which the surfaces are provided with the uneven patterns become the films with smooth surfaces through the calendering; and according to the calendering degree of the patterns, cutting the films into a plurality of small pieces only containing one pattern. The method has the advantages of simple manufacturing process, convenient deformation detection and low cost; and by using a characteristic that a high molecular polymer having a shape memory effect is used for shaping the shape memory anti-counterfeiting mark, the method can realize anti-counterfeiting on a wine bottle cap.
