Silver checkerboard labels with metalized back side and checkerboard manipulation protection. Once applied to the surface, on removal an irreversible "checkerboard" tamper evidence will detach itself from the face film. Labels which have been removed cannot be reapplied since repositioning will leave visible proof that tampering has taken place. Thanks to the special surface coating, excellent results can be achieved with thermal transfer printers equipped with conventional or near-edge print heads and using pure resin or wax-resin ribbons. The adhesive is recommended for low surface energy substrates, like some plastics and powder coatings. The tamper-proof effects are guaranteed up to +40 °C. THe smooth surface is equipped witha top coat designed for achieving excellent print anchorage with thermal transfer printers.
