Tamper Evident Labels

Describe the evidence you need: label fragmentation, a visible transfer message or damage at the opening. Destructible films and other security constructions behave differently. Submit the actual pack and an opening sequence so sample review focuses on a clear, recognizable change.

A bridge seal must fit the movement and geometry of both surfaces. Supply the cap diameter, shoulder profile, opening direction and filled samples. Trial application and opening after dwell, checking that the seal shows interference without lifting prematurely during normal packing and transport.

Treat it as an indication of interference rather than a universal prevention claim. Define what customers should look for and test realistic removal attempts on the proposed surface. A label that can be lifted intact or reapplied without visible change needs further evaluation.

Approve application conditions, dwell period, storage exposure and the visible failure you expect when opened. Include your carton coating or container finish and check more than one production-equivalent sample. Record photos of acceptable evidence so receiving inspection has a practical comparison.
