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
How to use?
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.
Why It Matters:
Fraud prevention: Deters unauthorized access and tampering.
Chain-of-custody compliance: Critical for legal, banking, and logistics sectors.
Accountability: Unique numbers enable full traceability.
