Closure seals

The advantages of the safemark^® closure seal

Our closure seals can be provided with many security features. Customs can carry out checking in international goods transport by examining these unique features. Furthermore, product-related data can also be stored by attaching appropriate RFID labels – to the extent of full traceability of the delivery chain.  Our security labels also protect packages and housings from unauthorised opening, because the closure label is irreversibly destroyed with this procedure.. Printed image destruction, the so-called VOID effect, also provides special transfer protection.

Clearly visible from a distance ....
... if the packaging has been opened. In the new seal printelectric®, an LED is integrated, which lights up in a tampering attempt by damaging the lock seal. This irreversible effect provides a reliable indication of the first opening. And this is also visible in the dark or from a distance, which saves time in the review and thus provides a significant process advantage.

Thanks to recent innovations, we are now able to print electronic components. Our high security seal printelectric® combines already known security features with innovative printelectric® technology from Witte. The seal seal printelectric® is applied in the same way as conventional closure seals.

After applying the seal seal printelectric®, it is firmly connected to the substrate. As with all Witte products, this seal also applies: we will find the right solution for every substrate so that the seal keeps its promises.
