Security seals

Security seals are mechanisms used to seal containers in a way that provides tamper evidence, detects theft or contamination, or unauthorised opening and entry. Essentra’s wide range of security seals are designed to meet the growing need for logistics security by providing physical tamper evidence and controlling accountability and inventory of stock.

Our security seals are used across a range of markets including the sealing of freight via air, land and sea, securing food containers and by banks to secure cash in transit.

All of our seals are compliant with international standards including ISO 17712:2013 and C-TPAT.
