Unauthorized opening? Unauthorized persons don’t stand a chance thanks to our tamper-proof closure seals!

There are packaging and containers that are more than annoying if they are opened by unauthorized persons. In certain areas (e.g. the manufacture of medicines or the housing of technical devices), the further use of the packaging depends on its sealed condition. Whether for reasons of data protection, confidentiality or counterfeit protection– our closure seals are ideal for officially sealing packaging, bottles and the like, so that unauthorized opening is prevented.

The Witte safemark® range includes a wide range of security label and security seals and seals that indicate tampering or unauthorized opening of packaging. We can offer solutions for both primary and secondary packaging.

The Falsified Medicine Directive 2011/62/EU, which was introduced by the European Union, is a decisive step for the pharmaceutical industry in the fight against counterfeit medicines. With a closure seal from our company, you are always on the safe side in this respect. The great advantage of our forgery proof seals is that they adhere to any type of surface, be it cardboard, plastic or metal packaging. Our special adhesive system makes it possible to immediately identify packaging once it has been opened and to ensure that the contents of the packaging reach the rightful recipient.

Official seals, which are used by the police at crime scenes, for example, are also part of our range.

High-quality closure seals from the specialist

Thanks to our many years of experience in the field of security products, we know exactly what is important. Our closure seals can be provided with various unique security features that enable them to be checked directly at customs in international goods traffic. As the seal or void label with void effect is irreversibly destroyed when opened (without authorization), it protects packaging and housings from any attempts at tampering. We also offer you the option of storing product-related data using RFID labels. This even goes so far that the supply chain can be fully traced.

Our closure seals also help in the fight against counterfeiting thanks to their exclusive security features, which are comparable to those of a banknote. Whether watches, jewelry, clothing or industrial spare parts: The tamper evident seals identify an original product as such at first glance.

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.

No more copying

Watches, jewellery, clothing or fan items – brand name items are required everywhere. The same applies to spare parts such as in the automotive industry. However, copies with substandard quality are often manufactured with supposed brand labels. Our safemark® security labels mark original products with a unique combination of features which are only known to the customer and the supplier. Our security seals are equipped with security features which can otherwise only be found on banknotes.
