Security seals are tamper-evident devices used to secure goods, containers, vehicles, meters, bags, equipment, etc. They provide a clear visual indication if unauthorised access, interference or tampering has occurred.
Once applied, a security seal cannot be removed without being broken or permanently altered. Any attempt to interfere with the seal leaves visible evidence, helping users quickly identify potential security breaches.
Security seals are widely used in logistics, transport, warehousing, manufacturing, retail, utilities, healthcare and aviation. Typical applications include trailers, containers, roll cages, sacks, emergency equipment, valves and meters.

Where applicable, certain seal types may be suitable for use in compliance-critical environments. Our sales team can advise on seals appropriate for applications requiring recognised industry or international standards.
