About Logi S Plastic Seal

Secure Logi S is a premium tamper-evident, pull-tight plastic strap seal made from durable polypropylene and reinforced with a strong metal clip. With its flexible strap, customizable tag, and tight locking through ultrasonic welding, it is designed for strength and reliability, featuring a secure locking mechanism that reveals clear signs of tampering – ensuring any unauthorized access is easy to detect.

In today’s complex supply chains, relying only on visible signs of tampering is no longer enough. Physical seals can be duplicated or fraudulently replaced – making unauthorized access difficult to detect and putting your operations at risk. That’s why Secure Logi S now features a high-security digital mark that adds a powerful layer of protection against duplication.

Building on traditional security features and customizable options like logos and UIDs, Logi S seals now feature a high-security digital mark with a hidden code that is difficult to duplicate. This unique digital ID ensures authenticity and strengthens traceability throughout the supply chain.

How the High-Security Digital Mark Helps:

  • Captures scan data, helping you know when and where a seal was scanned, adding a digital audit trail to your supply chain.
  • Strengthens supply chain visibility by linking seals with shipment or location-specific data for better traceability.
  • Prevents seal duplication and tampering with unique, encrypted digital identifiers that are nearly impossible to replicate.

Secure Logi S’s long adjustable tail and compact flag make it suitable for sealing everything from postal bags and courier shipments to tanker trucks and healthcare containers.
