Exploring The Different Types Of Security Seals

The primary use for a security seal is to deter and expose unauthorised access. Security seals like locks are designed for a specific purposes such as sealing cargo containers, meters, bags and much more. The purpose will determine the type of security seal applied.

Security seals can be broken into two key categories:


Indiciative Seals

Security seals that can be removed without the need for special tools. These seals are used in a wide variety of situations, either where the item to be sealed has no capacity, or necessity, for increased protection from forced entry. Indicative seals do vary in pull apart strength. For example, the seals used for fire extinguishers have a low breaking strain, as rapid access is essential. These seals can be removed by hand. In contrast, the security seals used to seal tautliners generally have a higher pull apart strength. This increases the wear capacity and reduces the opportunity for chance crime. An ordinary cutting tool such as a scissors is normally used for removal. These security seals also vary in design type, for example fixed length seals have a single sealing position versus adjustable length seals that have multiple sealing positions.


Barrier Seals

Barrier security seals cannot be removed without special tools. Barrier seals serve a dual-purpose: barrier protection and sealing. These security seals are used to prevent break-ins, protect cargo and improve supply chain integrity. This is achieved as removal tools are not always carried by thieves and removal is difficult to conceal. Common barrier seal types include bolt, cable and bar security seals. Bolt seals are regularly used to secure container and vehicle doors in order to protect high value cargo. Bolt cutters are normally required for removal. Cable security seals also have a wide list of applications including sealing containers, dangerous goods, drums, equipment, hatches, doors and more. Cable cutters are generally required for removal. Bar seals easily mount to containers and require both a power cutting tool such as an angle grinder and a cable cutter for removal.
