Custom Security Seal Labels
Tamper-Evident, VOID & Destructible Seals That Show Opening
A security seal is built to fail visibly when it is removed — destructible stock breaks into small pieces, VOID film leaves a "VOID" pattern behind, and neither can be lifted whole and reapplied cleanly. We produce these tamper-evident constructions with a custom VOID message and optional serial numbering, so closures, cartons and warranty seals show clearly if they have been opened.
Lift the seal and it shows opening — destructible stock fragments and VOID film leaves a readable residue behind.
What Tamper-Evident Security Seals Are
Security seals use special stock so removal is obvious at a glance.
Destructible
A brittle face stock that breaks into small pieces when peeled, so it cannot be lifted whole.
VOID Film
A film that releases a "VOID" pattern onto the surface or the label when it is removed.
Tamper-Evident
A seal across a closure or pack that shows opening at a glance once it is broken.
Non-Transfer
A construction that cannot be removed intact and reapplied to a fake or second pack.
How VOID and Destructible Seals Work
The evidence comes from how the stock is built — the construction is what breaks or leaves a mark.
What Happens When a Seal Is Lifted
A security seal is engineered to give way before the closure does. How it fails depends on whether the face is destructible or a VOID film.
- Destructible breaks apart — the brittle face tears into fragments when lifted, so there is no intact label to move to another pack.
- VOID leaves a mark — the film separates so a "VOID" or custom message stays on the surface, the label, or both.
- Cannot be reapplied cleanly — once removed, neither construction goes back without visible evidence of opening.

When to Choose Destructible, VOID or Tamper-Evident
Each construction shows tampering differently — choose by the kind of evidence you want left behind.
Choose Destructible
When a label must not survive removal at all — the face fragments so there is nothing intact to move.
Warranty & Asset SealsChoose VOID Film
When you want a clear "VOID" message left behind as visible evidence on the surface or the label.
