Marine Container Bolt Seal is a high-security, tamper-evident sealing device used to secure shipping container doors during transit. It consists of a steel bolt and a locking body, typically requiring bolt cutters for removal. Once locked, the seal clearly shows visible evidence of any attempted tampering or unauthorized entry. Bolt seals are widely used in marine cargo transport to prevent theft, ensure customs compliance, and maintain cargo integrity from origin to destination. Each seal carries a unique serial number and barcode for identification and tracking.
