JY250B-Adjustable Bead Security Seal for Trucks, Containers, Airline Catering & Distribution Boxes

The JY250B is an adjustable beaded security seal designed primarily for tamper-evident applications and identification management on trucks, shipping containers, airline catering carts, meal delivery boxes, cold-chain distribution boxes, logistics totes, and shipping containers. It features a beaded strap structure and a one-way locking mechanism; once sealed, the strap can only be tightened and not reversed. Removal leaves clear evidence of tampering, making it ideal for logistics scenarios requiring rapid sealing, serial number traceability, and protection against unauthorized opening during transit.

Technical Specifications & Manufacturing

The JY250B is typically manufactured via injection molding using engineering plastics such as PP or nylon, with the beaded strap, locking head, and locking aperture formed either as a single unit or through assembly. The locking head contains internal one-way locking teeth or a metal spring clip; when the tail of the beaded strap is inserted, the teeth engage with the beads to ensure a secure, one-way lock. Information such as serial numbers, logos, company names, contact details, barcodes, and QR codes can be applied using laser marking, hot stamping, or standard printing. The "250" in the model number generally indicates a length of approximately 250mm, though actual length, color, printed content, and tensile strength requirements can be customized. Standard colors include red, yellow, blue, green, white, orange, and black. As performance may vary based on material, specifications, and printing methods, specific parameters are subject to the confirmed sample or order.

Product Features

Key features of the JY250B include adjustability, tamper-evidence, ease of use, and clear identification. The beaded strap design allows for flexible adjustment of tightness based on the locking point, avoiding the limitations of fixed-length seals. Once locked, it cannot be removed without leaving traces of tampering, effectively reducing the risk of unauthorized opening during transport. The seal can be applied manually without tools, making it suitable for high-frequency, fast-paced logistics operations. Unique serial numbers, barcodes, or QR codes can be printed on the surface, facilitating verification via scanning by warehouse staff, drivers, recipients, and customers, thereby enabling batch traceability. Additionally, the product offers excellent weather resistance and durability, making it suitable for standard indoor and outdoor transportation environments. Carton packaging facilitates warehousing, distribution, and transport; packing quantities can be adjusted according to customer requirements.

Usage Instructions

Before use, verify the seal's serial number, color, and quantity, and ensure the locking head and beaded strap are undamaged. Thread the beaded strap through the locking mechanism of truck doors, container doors, airline catering carts, distribution boxes, or logistics totes, then insert the tail of the strap into the locking head. Pull the strap tight to the desired position, confirm the lock has engaged, and tug in the opposite direction to ensure it cannot be withdrawn. Record or scan the serial number, barcode, and QR code to complete the sealing registration. Upon receipt, the recipient should verify that the serial number matches and inspect the seal for integrity. To remove, cut the seal with scissors or a specialized tool; the seal is for single use only. If the seal is damaged, the number does not match, or the locking mechanism appears abnormal, take a photograph as evidence and report the issue immediately.

Application Scenarios

The JY250B is widely used for truck transport, container door locks, airline catering carts and boxes, cold chain distribution boxes, insulated containers, supermarket distribution boxes, postal/courier totes, and warehouse logistics totes. It is suitable for logistics companies, fleet operations, ports, airport catering, food distribution, pharmaceutical cold chains, e-commerce warehousing, and third-party logistics. It serves as an effective deterrent and traceability tool for processes requiring rapid sealing, tamper-evident inspection, serial number tracking, and handover verification.
