What Are Security Seals & Why They Matter in Logistics and Supply Chain

In today’s fast-paced logistics world, ensuring that goods reach their destination safely and untampered is crucial. This is where security seals come in — small yet powerful tools that help businesses maintain trust, prevent loss, and improve accountability across the supply chain.
What Are Security Seals?
In today’s fast-paced logistics world, ensuring that goods reach their destination safely and untampered is crucial. This is where security seals come in — small yet powerful tools that help businesses maintain trust, prevent loss, and improve accountability across the supply chain.
There are several types of seals used across industries:
  • Plastic Security Seals: Lightweight and cost-effective, ideal for courier packages or light cargo.
  • Wire Seals: Strong, flexible, and commonly used for meters, drums, or tankers.
  • Bolt Seals: Heavy-duty and ISO-certified for shipping containers and trailers.
  • Cable Seals: Provide higher strength and tamper resistance for industrial use.
  • Cattle Ear Tags: Used in agriculture for livestock identification and traceability.
At Protoseals, we design and manufacture all these types with precision and durability to meet global security standards.
Why Security Seals Matter in Logistics
Security seals are not just accessories—they are essential for maintaining the integrity of goods in transit. Here’s why they are so important:

Tamper Evidence

If a shipment is opened or manipulated, the broken seal provides immediate evidence of interference. This helps logistics managers quickly identify and address breaches.

Theft Prevention

A sealed cargo acts as a deterrent to potential theft. Drivers, warehouse handlers, and transporters know that seals are traceable and monitored.

Accountability and Tracking

Each seal carries a unique identification number, helping track and document the handling process throughout the supply chain. This adds a layer of transparency and accountability.

Regulatory Compliance

Many global shipping and customs regulations (including ISO 17712 for bolt seals) mandate the use of security seals to ensure international cargo safety.

Customer Trust

When customers receive sealed shipments, it builds confidence that the goods are untouched, authentic, and handled securely.

Security Seals in the Supply Chain Process
Security seals play a vital role at every stage of the supply chain:
  • Production: Seal finished goods before storage to prevent tampering.
  • Transportation: Secure containers, trucks, and tankers during transit.
  • Warehousing: Protect stored inventory from unauthorized access.
  • Delivery: Ensure customers receive safe and original goods.
By using Protoseals’ tamper-proof products, businesses can ensure end-to-end cargo security across local and international supply chains.
How to Choose the Right Seal
  • The type of cargo (lightweight, heavy-duty, liquid, etc.)
  • The transport medium (road, rail, sea, or air)
  • Regulatory standards for the destination country
