Tamper-Evident & VOID Label Material

Tamper-evident VOID label material is a security film built with a release layer that splits when the label is peeled, leaving a VOID or custom message on both the substrate and the label face. The change is permanent and cannot be reversed, so any attempt to open or move the label is immediately visible on inspection.

It is used for carton and case seals, electronics and warranty closures, service and calibration seals, and returns-fraud prevention, where evidence of opening matters more than physical strength.

Choose between total-transfer and partial-transfer effects, pick a colour and message layout, and match the adhesive to the substrate — the pattern releases differently on smooth plastics, painted metal, glass and rough board. Cold, hot and oily surfaces also change the result, so confirm with sample testing before rollout.

A security label that leaves a VOID message on the surface and the label when removed, showing that it has been tampered with.

Yes, custom text or patterns (such as a brand name or OPENED) can replace the standard VOID.

No — once lifted, the transfer is permanent and the label cannot be cleanly reused, which is the point.

Security seals, warranty labels, electronics and any closure that must show tampering.

VOID transfer film performs across standard ambient storage and application temperatures; extreme heat or cold can affect how cleanly the message transfers, so confirm your application and service temperature and we will match the film and adhesive to it.

Yes, the matte or gloss security film accepts flexo, offset or digital printing, and custom text, serial numbers or QR codes can be added alongside the VOID message for combined authentication and tamper-evidence.

Yes, request a free sample with your custom message or standard VOID pattern, plus the datasheet, so you can test the transfer effect and adhesion on your own substrate before committing to a production run.

Stocked grades start from 1 jumbo roll. Custom constructions or coatings typically start from 3,000–5,000 square meters, depending on complexity.

Permanent, removable, deep-freeze, high-tack or wash-off adhesive (water-based or hot-melt), on white glassine, PET or CCK/kraft liner — matched to your surface and environment.
