Self adhesive thermo sensible labels that thermo retracts if you try to heat it
Heat sensitive labels are strongly adhesive and if removed will tear the cardboard, and the tampering will be evident.
One of the most frequently used methods to fraudulently remove a security label is to heat the surface with a simple hair dryer to make the adhesive more "liquid" and reduce the hold capacity to zero. In this case the heat sensitive label will shrink, making the tampering evident and destroying the label.
NB: Printing and application tests must be carried out.
