The ideal humidity level in the prep and packaging area is crucial for maintaining the integrity of sterile items and preventing issues such as microbial growth or damage to packaging materials. A humidity level of around 50% strikes a balance that helps to ensure that wrapped items do not become damp, which can compromise the packaging and lead to sterility failures, while also avoiding excessively dry conditions that can contribute to static electricity and fragility of packaging materials.

Maintaining this level of humidity is important for ensuring that the barrier properties of sterilization wraps are preserved, thus ensuring that the items remain sterile until they are used. Being too high in humidity can lead to condensation on the items or packaging, while too low humidity can cause wraps to become brittle or preclude proper sealing. Therefore, 50% is considered optimal for effective prep and packaging in order to ensure a successful sterilization process.
