Void Seal: Security Label with “Proof-of-First-Opening“

While conventional adhesive tapes do not offer sufficient protection against unnoticed opening of a container, Void Seals provide effective tampering protection:

Removal of the seal “triggers” permanent display of a previously covert void effect integrated in a colored field
Unique designs of the void effect, e.g. customer’s logo, are available
The void message remains visible even if the seal is carefully re-applied to the surface.
