FAQ
Q: What is a security seal?
A. A security seal is a one-time tamper-evident device. Once locked, it cannot be opened without damage, leaving visible evidence of tampering. Traditional lead meter seals are named lead seals; now the industry calls all disposable anti-tamper seals security seals.
Q: Are all security seals made of lead?
A: No. Modern bolt seals, cable seals and plastic seals are lead-free. Only old-style meter cup seals contain lead; lead-free meter seals are widely used for environmental compliance.
Q Are all security seals single-use?
A: Genuine security seals are single-use. They cannot be reset without damage. Reusable seals do not meet tamper-evident requirements and are not acceptable for customs or container shipments.
Q. Are lead seal, security seal and lock seal the same product?
A. The terms are often mixed in daily business. Broadly, lead seal = security seal. Narrowly, lead seal refers to meter cup seals. Plastic types are plastic pull-tight seals; container versions are high security bolt seals.
Q: What does tamper-evident mean?
A: Any attempt to pry, cut or open will leave visible, irreversible damage marks.
