Tamper Evident Technology

DUNMORE's security film technology is used in conjunction with our customers’ products to create the tamper evident or void evident effect. For example, DUNMORE provides the surface destruct film that is used by automotive manufacturers on the door label with the vehicle information. If the label is removed, it becomes obvious that it has been tampered with. DUNMORE's film typically works with a pressure sensitive adhesive in label, seal or tape format to provide the tamper evident security function.

Different tamper evident standard patterns can be used for the message, including "void", "invalid" and certain geometric patterns such as repeating circles. Custom void messages are also possible - Contact DUNMORE for details.
