The disposable plastic seal is a self-locking anti-tamper device made from high-strength engineering plastic. Once locked, it cannot be opened without damage — forced removal leaves irreversible breakage marks. Widely used for courier bag sealing, truck door security, returnable container locking, meter tamper-proofing, and fire equipment management. Key advantages: single-use, tamper-proof, and cost-effective.
The seal features a one-piece head and strap. Inserting the strap into the head automatically locks it — the tighter the pull, the stronger the lock. Each seal can be hot-stamped or laser-engraved with a unique serial number and company logo for full traceability.
Compared to reusable padlocks or standard cable ties, the disposable plastic seal completely eliminates the possibility of reuse. Obvious damage upon removal allows personnel to instantly identify unauthorized access to goods or equipment.
