UKVIN Group technical guide · Label materials
Tamper-evident versus tamper-proof
Tamper-evident means a product is intended to provide a clue that interference may have occurred. It does not mean access or removal is impossible.
Material and application considerations
Claims should reflect actual material performance. Labels can fail through poor application, dirt, heat or use on incompatible finishes, even if the film itself is designed for security.
Practical use case
A VOID mark can be one part of a documented inspection routine but cannot guarantee that an object was never opened.
Selection checklist
- Describe the intended evidence
- Test realistic conditions
- Avoid absolute security claims
How to specify an order
Record the substrate material, dimensions, required quantity, intended printing method, approximate service conditions and any special handling. An adhesive or face film that looks appropriate in a catalogue may behave differently when applied to a textured, coated or curved surface. Test a sample before committing to bulk production, and confirm that any technical performance claim is supported by the actual supplier's specification.
Independent supply and limitations
UKVIN Group supplies independent label and identification materials. A material guide is not an approval for use as a statutory vehicle plate or manufacturer-authenticated VIN label. Where the intended item serves an official identity or certification purpose, consult the responsible issuer before ordering.
