Security seals prevent tampering with shipping containers, freight, and totes to safeguard equipment, tools, and other items. They're commonly used in the transportation, pharmaceutical, cash transit, air cargo, and food industries. Tamper-evident seals, also known as indicative seals, show signs of damage when opened. They provide tamper evidence rather than prevent access. High-security and C-TPAT compliant high-security seals, also known as barrier seals, require heavy-duty tools to open. They provide a physical barrier to accessing property. Security seal presses are used with lead and wire seals to seal the wire.
