Embodiment 1
[0021] The manufacturing method of the shape-memory anti-counterfeiting label with permanent memory information of the present invention comprises the following steps: extruding each component of the formula amount into a sheet material after mixing in an extruder, and putting the sheet material in Heat it on the heating machine to produce deformation, and then press the pattern or text on the sheet material to obtain a shape memory anti-counterfeiting substrate with permanent memory information. After the substrate is printed, glued, and die-cut, the information with permanent memory is obtained. Shape memory anti-counterfeiting mark. The extrusion temperature of the extruder is 190 degrees, and the screw speed is 350 r / min.
[0022] Among them, the polymer material is prepared from the following components in parts by mass:
[0023]
[0024] When identifying: Put the anti-counterfeit label in hot water above 70 degrees or use a lighter to grill the anti-counterfeit label...
