Shape memory polymer security label is labels made by our exclusive SMP(Shape Memory Polymers) label film, with much higher security level than the ordinary label film/substrate.

The secret that made SMP security label so distinctive and impressive is the exclusive SMP label film and the Shape Memory Polymer technologies involved in it.

The face material of SMP security label is SMP label film, which can store embossed covert message information inside. To verify the label by exposing it to 65°C heat, the covert message in the face material will be activated and released magically.
