Security Seal

The security seal is a single-use tamper-evident device used to indicate whether a container or package has been illegally opened. It is widely used for sealing and tamper management of parcels, totes, containers, document bags, padlocks, and equipment.

Made of high-strength PP, it features a self-locking ratchet mechanism that cannot be removed by hand once locked. Forced cutting leaves irreversible damage, preventing unauthorized opening, replacement, or tampering. The tail includes a writable label area for printed or handwritten serial numbers and identification, enabling traceability. Available in multiple colors for differentiation by customer, batch, or scenario.

Tamper-resistant, pull-resistant, and replication-proof. Easy to use and cost-effective, widely applied in express logistics, airline baggage, judicial evidence, bank transport, and container shipping — an ideal tool for end-to-end security and tamper-evident traceability.

Primary Functions

Container Security Seal-Provides one-time sealing for parcels, totes, containers, document bags, padlocks, equipment, etc., indicating whether tampering or unauthorized opening has occurred.

Tamper-Evident Warning-Once locked, cannot be removed by hand. Forcible cutting leaves irreversible damage marks, effectively identifying illegal opening.

Traceability Information-The tail end can be marked or printed with serial numbers, barcodes, or other data, enabling full-process traceability when integrated with warehouse management or proof-of-delivery systems.

Color-Coding for Identification-Available in multiple colors for visual sorting by customer, region, batch, or risk level, facilitating quick recognition and category management.

Single-Use Design-Cannot be restored once removed, eliminating safety risks associated with reuse.

Usage Notes

Verify that the seal is intact, the self-locking mechanism functions properly, and the serial number or printed information is clearly readable.

Insert the tail end of the seal through the locking hole and tighten until the ratchet is fully engaged. After hearing a "click" or feeling the ratchet lock, pull firmly to confirm that it cannot be dislodged.

Record the seal number or write information manually on the label area before use, and link it to the corresponding cargo or waybill.

Cut the seal using dedicated seal cutters or heavy-duty pliers. Do not pull or yank forcibly by hand.

Used seals must be discarded immediately and shall not be reapplied to any item for sealing purposes.
