What should packaging prevent during normal handling operations?

The primary focus of proper packaging during normal handling operations is to prevent contact between items. This is essential because physical contact can lead to scratches, dents, or contamination, compromising the integrity and functionality of the items being transported or stored. When items come into contact with each other, especially during movement or handling, there's a risk of creating foreign objects that could interfere with later operations, particularly in sensitive environments like aviation or manufacturing.

While the other options address important considerations, such as protecting packaging from damage or moisture absorption, these aspects do not directly address the critical concern of preventing foreign object introduction through item contact. Similarly, while ensuring the mixing of components might be relevant in certain contexts, the priority lies in ensuring that items do not touch one another to safeguard against damage and the introduction of foreign materials. Thus, maintaining a barrier between items is fundamental to effective Foreign Object Elimination practices.
