What is the purpose of a seal on the packaging?

• A. To indicate the pack is full
• B. Show if pack has been opened and not resealed
• C. To mark the lot number
• D. To show the hazard class

Answer: (B)

Packaging seals are there to provide tamper evidence. They show whether the pack has been opened and not resealed, which helps confirm the contents haven’t been accessed since it left the manufacturer. If the seal is intact, it suggests the package remained unopened; if it’s broken or disturbed, it indicates possible tampering and warrants following proper inspection or replacement procedures. The seal isn’t a fullness indicator—the actual contents determine fullness. Lot numbers are typically printed on the label or container, not the seal itself, and hazard class is conveyed by standard labeling and markings rather than the sealing tape.
