Unimark Security Bag (often shortened to “security bag” or “tamper-evident bag”) is a strong, disposable envelope/pouch designed to protect high-value or sensitive items in transit or storage. Its core feature: once sealed, it cannot be opened without leaving irreversible, visible evidence of tampering.
Key Features:
- Tamper-evident seal: The closure strip leaves “VOID OPEN” or similar marks if opened; cannot be resealed cleanly.
- Unique serial number: Printed on the bag and a detachable receipt strip for tracking and accountability.
- Heavy-duty material: Tear/puncture-resistant plastic or fabric.
- Security welds: Sealed edges prevent tampering from sides/bottom.
Application:
- Cash, coins, and bank deposits
- Confidential documents, IDs, passports
- Evidence collection (law enforcement)
- High-value goods (jewelry, electronics)
- Pharmaceutical and medical supplies
- Place items inside.
- Peel off the release liner and press the flap to seal (adhesive bonds permanently).
- The bag is now tamper-evident: any opening attempt triggers irreversible markings.
- Use the unique number for logging and chain-of-custody records.
- Fraud prevention: Deters unauthorized access and tampering.
- Chain-of-custody compliance: Critical for legal, banking, and logistics sectors.
- Accountability: Unique numbers enable full traceability.
