Both stamping foil and tamper proof use PET as a based material and coarting with release layer, aluminum layer, etc, and the final effect looks similar, however, the two material is quite different from each other.

Stamping Foils adopt stamping machine to release layers from the PET carrier to the surface of substrates upon application of heat or/and pressure. And this material is widely used for stamping on paper, textile, plastic, etc.

While the tamper proof material is supposed to coating adhesive at first, and then adopt machine to release layers. And this material is widely used as holographic labels. and it is classified into low residue type and high residue type. popular pattern is different sizes of VOIDs and beehive.
