Frequently Asked Questions
What is a plastic security seal?
A plastic security seal is a tamper-evident device made of plastic that locks permanently once sealed. It provides visible evidence if the seal has been broken or tampered with. Each seal has a unique serial number for traceability.
What is the difference between pull-tight and padlock plastic seals?
Pull-tight seals have an adjustable strap that tightens like a cable tie (for various sizes). Padlock seals have a fixed locking arch (for specific applications like bags). Both are one-time-use and tamper-evident.
Can plastic seals be removed without tools?
Most plastic seals can be removed by hand by pulling hard or cutting. They are designed to show evidence of tampering, not to be physically unbreakable like bolt seals. The tamper-evident feature is the unique serial number and the irreversible locking mechanism.
What is the MOQ for custom plastic seals?
MOQ for stock plastic seals with sequential numbering: 1,000 pieces. For custom-printed seals with logo: 5,000 pieces. Contact us for exact pricing.
