Plastic security seals are widely used tamper-evident devices designed to secure goods, containers, and equipment during transportation and storage. They are typically made from durable plastic materials such as polypropylene (PP) or nylon, which provide strength, flexibility, and resistance to environmental conditions. Once locked, the seal cannot be removed without breaking, making it easy to identify any unauthorized access.

These seals are commonly used in logistics, courier services, airline cargo, utility meters, retail packaging, and warehouse management. Each seal often features a unique serial number, barcode, or custom marking that allows easy tracking and verification. This helps companies improve security, prevent tampering, and manage inventory more efficiently.

Plastic security seals are also valued for their lightweight design and simple locking mechanism. They can be applied quickly without special tools, saving time in high-volume operations. Available in different sizes, colors, and styles, they can be customized to meet specific security and identification needs across various industries.
