Frequently Asked Questions

Q: What does the unique serial number on each seal do?

A: Each individually numbered security seal has a unique serial code that allows you to log, track, and verify which seal was applied to which item or container. This makes it easy to detect any unauthorized removal or tampering and maintain a proper chain of custody.

Q: Can these seals be used outdoors or in extreme conditions?

A: Yes! These seals are made from high-density polypropylene, making them weatherproof and resistant to temperature fluctuations, moisture, and UV exposure — suitable for both indoor and outdoor applications including cargo containers, luggage, and industrial storage.

Q: What pack sizes and colors are available?

A: These tamper-proof plastic padlock seals are available in packs of 50 or 100. Multiple color options are offered, allowing you to color-code seals by department, shipment type, priority level, or any other organizational system you prefer.
