What is the main reason to avoid stacking wrapped trays?

Avoiding the stacking of wrapped trays is primarily important to prevent damage to the contents within the trays. When trays are stacked, the weight of the items on top can create pressure and stress on the materials below, which can lead to physical damage such as tears in the wrapping or crushing of the items inside.

This is particularly crucial in a sterilization context, where maintaining the integrity of the packaging is essential for ensuring that sterility is preserved until the items are used. While other concerns like sterility loss, excessive weight, or the risk of falling could be relevant in different scenarios, the direct impact on the structural integrity and potential for physical harm to the items makes avoiding stacking a key practice in central service operations.
