In today’s fast-paced logistics and supply chain industry, ensuring the safety and integrity of goods during transit is more important than ever. Businesses rely heavily on security seals to protect shipments from tampering, theft, and unauthorized access. Whether transporting goods locally or internationally, choosing the right type of security seal plays a crucial role in maintaining trust and compliance.

This complete guide explores the different types of security seals used in the logistics industry and how they help safeguard your cargo.

What Are Security Seals?

Security seals are tamper-evident devices used to secure cargo containers, trucks, bags, and packages. They act as a visual indicator that a shipment has remained intact throughout its journey. Once applied, most seals cannot be removed without breaking or showing clear signs of tampering.
