An indicator of a plastic seal security rating is whether it has obtained an ISO PAS 17712 rating. US Customs-Trade Partnership Against Terrorism (C-TPAT) and the World Customs Organization’s Framework of standards, endorsed and encouraged the use of ISSO compliant seals. Let’s see the categories of plastic seals.

Plastic seals can be split into two main groups: single use and reusable. Single use plastic seals are typically made of plastic or metal, and the used material and production technology is the key to their security level. Reusable plastic seals are usually electronic or mechanical rather than just made form plastic, and if purely plastic, only one part is reusable.
