Physical Characteristics


Bubble Tag™ is produced in a polymer with a proprietary formulation and a high resistance to heat, friction, UV and chemical attacks. The probability of generating 2 identical Bubble Tags™ on a surface of 1cm2 is less than 1/10160.


The thickness of Bubble Tag™ can vary from 200 to 500 μm depending on the applications needs. The bubbles cannot be destroyed or moved; the generation process is not reversible.



Bubble Seal™ is produced on metallized tamper evident foil. A removal attempt causes his visual alteration. This characteristic reduces the risks of removing and repositioning a seal on an illegitimate item.


Bubble Card™ integrates into its inner layer a Bubble Tag™ visible in transparency on both sides of the card. Any attempt to remove the Bubble Tag™ leads to the destruction of the card. Bubble Cards™ can be made of PVC, PC, PET and Metal (brass, steel).
