What must inner packaging provide for liquids?

• A. Ventilation holes to allow airflow
• B. Leakproof primary receptacles and secondary containment with absorbent material to control leaks
• C. A decorative outer wrapper
• D. A loose packing material only for cushioning

Answer: (B)

The key idea is that inner packaging for liquids must create a reliable barrier to prevent leaks from escaping during transport. This means using a leakproof primary container to hold the liquid, placed inside secondary containment that can capture any leaks. Adding absorbent material inside the secondary containment provides an extra safeguard by soaking up leaks and helping contain spills if they occur. Together, this setup protects people and the environment and keeps the shipment compliant. Relying on ventilation holes, a decorative outer wrapper, or loose cushioning alone does not control leaks, so they’re not sufficient for liquids.
