Security bags are most commonly seen in duty-free stores to ensure that the items placed inside have not been tampered with. Additionally, evidence bags used by law enforcement agencies ensure the safety of items or classified documents placed inside, preventing any concerns about tampering or swapping of contents during transportation.
Tamper-Evident Security Bag
When the seal of the security bag is opened, it reveals words such as "VOID" or "Open." Once this seal is broken, it cannot be restored, allowing for the verification of the package's integrity.
If exposed to high temperatures, the seal will show red marks (irreversible thermochromic ink). If submerged in water or exposed to excessive moisture, the word "WATER" will disappear. These anti-counterfeit features ensure the integrity of the security bag and proper storage conditions.
