A bespoke concept is the basis for your perfect security seal solution. It all starts with an analysis of your requirements in the sealing process. This forms the basis on which we identify the ideal solution. Therefore, we believe it is vital to work closely with you to define the following key data: 

  • What type of item do you need to seal?   
  • Could one of our standard products meet your sealing challenge? Or could we modify a standard product or even find a special solution that fully meets your needs? 
  • What mechanical or environmental forces are relevant for you? This gives us an clear indication of the raw material we should specify and seal design we should apply for your solution.
  • What demands do these place on security or the tamper-evident protection that the security seal will afford? This gives us a point of reference with regard to the technical product design. 
  • What demands do you place on the handling of the security seal? This includes the attachment, checking and removal of the security seal. 
  • How do you document the unique serial numbers within your process? Are these indicated on the relevant documents in handwritten form or via an electronic reader system? We are able to implement the most suitable numbering or barcode system for you, including 2D code or even an RFID solution. 
  • Do you need a variety of different colours of plastic for efficiency in your logistics process? We can certainly find the ideal solution for you!
  • Have you particular requirements with regard to packaging? Put us to the test and we will come up with the solution you require. 

Summary: Only by understanding your requirements with regard to sealing, control and security of your containers and products can we focus our thoughts on function, technical design and the logistics of your complete security seal solution.
