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 The self-locking mechanism is irreversible — once locked, the strap cannot be withdrawn without destroying the seal, giving inspectors, supervisors and logistics teams a clear visual indicator of whether a container, cart or bag has been opened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.
