Substrate response
Identify painted metal, powder coat, plastics or glass. Texture and surface energy can change the transfer pattern or fragmentation behavior.
Application solution / Security & Tamper Evidence
Make attempted removal visible at the point of access.
Define the evidence you need first. Then select a security construction around the substrate, access geometry and inspection conditions.
Start with the question
What should an inspector see after an attempt to open or remove?
02 / The application challenge
What must the label withstand?
A security seal is useful only when its response is visible and understood. Transfer patterns, fragmentation and removal behavior vary with the surface and conditions; the intended evidence needs to be demonstrated on the actual enclosure.
Dwell and temperature
Define the time between application and inspection. Evaluate removal at the relevant temperatures after the specified adhesive dwell.
Access geometry
Position the seal across the intended opening path with usable contact area on both sides. Avoid bridging unsupported gaps.
Inspection and replacement
Define acceptable evidence and authorized replacement procedures. Tamper evidence helps reveal interference; it does not physically prevent access.
03 / Recommended approach
Match the approach to the application.
Compare the visible evidence left by different security-label constructions.
- Electronics housings and equipment enclosures
- Access panels and service openings
- Warranty protection and serialized security seals
- Asset security and inspection identification
Serial numbers, sequential numbering and barcode / QR data support seal assignment and inspection records. Establish the data format and duplicate-control rules before artwork approval. A printed identifier supports a security workflow but does not by itself authenticate an asset.
04 / Construction & technical options
Select the complete printed construction.
Transfer security films
VOID transfer and partial-transfer VOID options chosen around the desired visible pattern and residue on the substrate.
Non-transfer options
Security films that show the selected removal response while limiting transfer to the surface, subject to substrate evaluation.
Destructible / fragmenting films
Frangible constructions for warranty and security seals where break-up on attempted removal is the intended evidence.
Compliance and marking requirements
- RoHS / REACH and project-specific material requirements can be addressed through the selected construction.
- Security behavior and equipment certification are separate requirements. Define evidence acceptance and any required documentation for the final application.
05 / Selection & validation
Evaluate the label in its real conditions.
Evaluate application and attempted removal on representative surfaces after the intended dwell time. Record transfer, fragmentation, visibility and residue under relevant temperature conditions, then agree what inspectors should treat as evidence of interference.
06 / Discuss your application
Start with your application.
Tell us what needs identifying and where the label will be used. A short description or drawing is enough to begin.
