1. A sterilization wrap system comprising:
an exterior panel comprising a permeable nonwoven material having barrier properties and having a first surface and a second opposing surface, the exterior panel having a first level of translucence; and
an interior panel comprising a permeable nonwoven material having barrier properties and having a first surface and a second opposing surface, the interior panel having a second level of translucence that is higher than the first level of translucence of the exterior panel, wherein the difference between the first level of translucence and the second level of translucence allows for identification of a breach.
