Bolt Seals

Bolt seals are mechanisms used to seal and secure cargo containers, such as shipping containers, trucks and trailers. These prodcuts provide tamper evidence in case of infringement. In this way bolt seals help to detect cargo theft or contamination. These security seals have a relative high breaking strength and therefore also provide an added layer of security.

Cable Seal

Cable seals are types of security seals or tamper evident seals. Security cable seals have, compared to for instance bolt seals, a more versatile application as the length of the locking mechanism can be variable. Cable seals can be subdivided by the material of the body, like on this page, but also by locking mechanism and adjustability of the length of the cable. There are nonadjustable and adjustable cable seals, such as pull tight cable seals. Moreover, cable security seals can be one time usable, but reusable cable seals exist as well.

Tamper evident seals are things, such as labels, plastic ties or metal bolts, which are placed on a product or package to easily detect unauthorized access to the protected object. If the tamper evident seal is removed it will self-destruct which results into a clear proof of tampering. Sealed objects can vary from a small jar of jam to a big shipping container.


Security seals are types of tamper evident seals and mechanisms to seal shipping containers or truck trailers. They are used to help detect theft or contamination. As the name implies, security seals also provide a level of security.
Often used security seals are bolt seals, cable seals, metal seals and plastic seals. Security seals that meet ISO 17712:2013 standards are classified as high security seals. High Security seals, also called barrier seals, are constructed with the intent to delay intrusion. They cannot be opened by hand and special tools, such as bolt cutters, are needed to remove the security seal. ISO 17712:2013 high security seals are CTPAT compliant and are accepted by customs all around the world.
