Destructible labels and VOID-pattern labels are different tamper-evident constructions. Select the intended evidence on the real surface instead of describing all damage or residue as frangible.
A changed seal can indicate disturbance of the label or the defined closure. It does not by itself prove who opened it, what happened to the contents or whether a product is genuine.
1. Name the mechanism before the residue
A destructible face is intended to fragment or tear during attempted removal when the bond and conditions support that behaviour. It is not necessarily paper: constructions differ.
A VOID or other transfer-pattern system uses a different mechanism. Depending on the grade, the visible change can be in the removed label, on the substrate or both; clean release with no visible substrate residue is not a universal rule.
2. Define the evidence and the inspector
State which change must be visible, where it appears and who checks it. Agree acceptable fragments, transfer pattern or other damage using an approved sample.
A large amount of residue is not automatically better security. Consider whether the evidence is recognisable, can be covered or replaced, and what inspection and response actually happen.
3. Test the actual surface and application
Identify the substrate, coating, texture, contamination, curvature and application temperature. Include dwell time before the first removal attempt and relevant storage conditions.
Use a practical comparison such as the table below. Grammage, adhesive family or a pre-cut shape alone does not qualify a seal.
| Construction | Observe on the actual item | Do not infer |
|---|---|---|
| Destructible face | Fragmentation or tearing after the specified dwell and removal | Every surface produces the same fragments or residue |
| VOID or transfer pattern | The specified change in the face, substrate or both | All grades transfer a message onto the package |
| Peel-removable identification | Release and surface condition for its intended use | Clean removal is tamper evidence or proof of authenticity |
4. Run printing, opening and reuse trials
Inspect the face after printing, converting and application so accidental cracking is not confused with tamper evidence. Check the chosen printer or press and actual layout rather than assuming one process suits every grade.
Test the intended opening or removal method and attempted reapplication after the relevant exposure. On reusable containers, also assess cleanup and whether a different removal mechanism would suit the workflow.
If contact-sensitive use is proposed, identify actual contact and transfer conditions and obtain appropriate material information. An external label location alone does not establish suitability.
FAQ
Are frangible and VOID labels the same?
No. Destructible faces break; transfer-pattern systems reveal a designed change. Define the mechanism and the expected visible evidence for the selected grade.
Will a destructible face always break on removal?
Not on every surface or under every condition. Confirm the adhesive, application, dwell and removal trial on the actual item.
Can a code be printed on a tamper-evident label?
Assess the chosen print system, position and readability before and after the intended event. The code and physical evidence are separate checks.
Does a disturbed seal prove the contents are counterfeit?
No. It is evidence to interpret within the defined inspection process; product authenticity and the condition of the contents require separate verification.
