What Is Tamper Evidence?
Understanding Tamper Evidence
Tamper evidence does not stop someone opening a pack, it makes the act impossible to hide. Breakable seals, void labels, and tear strips all leave a permanent mark once disturbed, giving an instant visual cue that a product may no longer be safe or genuine.
This matters most where contents can be adulterated, refilled, or swapped, such as pharma, food, and high-value goods. Tamper evidence works hand in hand with authentication: one proves the item has not been opened, the other proves it is genuine.
Key Components of Tamper Evidence
Why Tamper Evidence Matters
Even a genuine product can be unsafe if it has been opened, refilled, or adulterated in the supply chain. Tamper evidence protects integrity by making any interference visible, which safeguards consumers and shields brands from liability.
- Reveals any opening or interference at a glance
- Protects against refilling, swapping, and adulteration
- Reassures consumers that contents are intact
- Supports safety and regulatory compliance
- Works alongside authentication for full assurance
- Hard to defeat without leaving a trace
How Acviss Supports Tamper Evidence
Acviss security labels combine tamper evidence with authentication, so a single feature shows both that a product is genuine and that it has not been opened. Certify ties each unit to a non-clonable identity, while tamper-evident constructions reveal any interference.
This pairs with tamper-proof labels and broader packaging security to protect product integrity end to end.

On its own it proves the pack has not been opened. Combined with authentication, it also confirms the product is genuine.
No. A well-designed seal cannot be opened and resealed without leaving a clear, irreversible mark.
