Tamper-Evidence Mechanisms Explained

Void Footprint Pattern (B-7546)

Uses a differential release coating between the adhesive and polyester face film. Removal breaks the chemical bond, permanently exposing a bright "VOID" message on the asset that cannot be smoothed back down.

Destructible Cast Vinyl (B-351)

The tensile strength of the cast vinyl face is lower than the bond strength of the aggressive acrylic adhesive. Any attempt to lift a corner causes the material to chip away like an eggshell.
