Numbered plastic security seal key features – sequential numbering, self-locking mechanism, high-tenacity PP

Tamper-Evident, Sequentially Numbered — One Seal, One Unique ID

This disposable plastic security seal is a one-time-use, tamper-evident locking device made from high-tenacity PP. The self-locking mechanism is irreversible — once locked, the strap cannot be withdrawn without destroying the seal, giving inspectors, supervisors and logistics teams a clear visual indicator of whether a container, cart or bag has been opened since sealing. Sequential numbering provides a unique ID for every individual seal, enabling batch tracking, inspection records and chain-of-custody documentation without additional tagging. Guangdong Xinghan supplies security seals to airline catering companies and ground handling operations in China; the same specification is available for international institutional buyers.

High-Tenacity PP, Bend-Resistant — Built for Operational Environments

High-tenacity polypropylene resists bending and tearing under the normal handling forces of airline galley carts, baggage trolleys and cargo loading — unlike standard PP, which can crack or deform at bend points, compromising the tamper-evident function. The ribbed strap body improves grip for tightening in gloved-hand environments. The locking head is sized for consistent fit on standard airline catering cart latch points and cargo seal loops. At 230 mm / 9 inch length, the seal accommodates the full range of airline cart and container seal loops without excess strap that catches on adjacent equipment.

Airline Catering, Baggage & Cargo — Three Security Applications from One Seal

In airline catering operations, these seals are applied to galley carts and meal container lids to prevent tampering between kitchen and aircraft. In baggage handling, they seal passenger bags and carry-on items during special handling. In cargo and institutional logistics, they provide cost-effective tamper evidence for sealed containers, evidence bags and document pouches. The sequential numbering system integrates with existing documentation workflows — supervisors log the seal number against the cart or shipment record at the point of sealing.

Custom Numbering, Barcode, Color & Logo — Configured for Your Security Program

Customization covers the sequential numbering range (starting number and digit count), barcode or QR code addition for scan-based tracking, seal color (for visual differentiation by department, route or shift) and logo printing. Custom seal lengths for non-standard application points are available. MOQ is 50 cartons (250,000 pcs); lead time is 15–25 days.

Frequently Asked Questions

Quality checks for this product

For these numbered security seals, the approved sample is retained as the written acceptance standard, and every batch is inspected against it - not against a description. The four-stage inspection system (incoming material, in-process control, finished goods, packing) checks numbering sequence, strap and locking specifically, under ISO 9001 / ISO 14001 / ISO 45001 / ISO 22000 management systems. Batch records are kept per SKU, so any drift is traceable to its cause.

How do you guarantee that numbering is unique across our entire order?

Sequential numbering is printed per your specification - starting number and digit count are confirmed before production, and the numbering sequence is verified at printing. The range is allocated to your order so no two seals in your supply carry the same number. If you need to extend the range on reorder, we continue from the agreed point.

What happens if a seal is locked by mistake - can it be reused?

No. The seal is a one-time-use device by design: once the strap is locked, it cannot be withdrawn without breaking the seal. This is intentional - it is what makes the seal tamper-evident. If mistakes happen in training, the cost of a seal is far lower than the risk of an unverifiable seal in your chain.

Can the seal be combined with a barcode or QR code for scanning?

Yes. Barcode or QR printing is available on the seal body for scan-based tracking, in addition to sequential numbering. Confirm the code format and scanner type at inquiry so we can size the code area and verify readability on the physical sample.

What documentation do you provide for our security audits?

Material test reports for the high-tenacity PP are available for qualified orders, and we can provide a sample of the numbering and locking specification for your audit records. Each batch is inspected against the approved specification before shipment.
