Leakage can damage other cargo, passenger baggage, even the aircraft itself.
To help avoid such problems, Delta has developed the following guidelines. Inner Package Completely enclose product in strong, securely sealed polyethylene bags. Pack the bags securely and pad them to avoid shifting. Outer Package Packages should be able to withstand shock and to be stacked at least five units high as resistance to external punctures is critical. Molded polystyrene containers require corrugated outer boxes.
