What impact does opening an external unit pack stored in unit-of-issue packaging have on shelf-life?

Opening an external unit pack stored in unit-of-issue packaging typically does not negatively impact the shelf-life of the item. This is because the shelf-life is primarily determined by the product's formulation and how it's designed to be stored, rather than the act of unboxing it. In many cases, properly stored products within their unit-of-issue packaging can remain viable even after the outer layer is removed.

However, it's essential to consider that while opening may not immediately affect shelf-life negatively, factors such as exposure to environmental conditions—like moisture, temperature changes, or contamination—might still play a role in maintaining the quality of the contents after the packaging is opened. Therefore, users must ensure to follow proper handling and storage guidelines after opening to preserve the item's integrity as much as possible.

This understanding emphasizes the importance of training in the Shelf-Life Program, to help personnel make informed decisions regarding the handling and storage of supplies.
