SL-52F Tamper Proof Adjustable Plastic Seals For Shipping(SL-52F)

The SL-52F plastic seal is an adjustable pull-tight security solution designed for container seals, truck seals, trailer seals, and logistics cargo control where strong tamper evident seals and reliable seal security are required. It is widely used in transport, warehouse operations, and export shipping systems that need consistent tamper protection and fast application.

Built with a self-locking internal structure, the SL-52F provides high tensile strength and stable locking performance, making it suitable for shipping seals, shipping container seals, and security seals for containers in demanding logistics environments. Once locked, it becomes single-use and cannot be reversed, ensuring clear tamper proof seal evidence if any interference occurs.

The seal can be customized with serial numbers, barcodes, logos, and printed markings, supporting security labels, tamper tags, and cargo traceability systems for better shipment identification and audit control. It is commonly applied in freight forwarding, warehouse management, courier logistics, and industrial transport operations where durable plastic seals and container security seals are required.
