Abstract

A method of using a sterilization wrap system including a permeable material having barrier properties and having a first surface and a second opposing surface, the exterior panel being substantially opaque or having a first level of translucence, and an interior panel including a permeable material having barrier properties and having a first surface and a second opposing surface, the interior panel having a level of translucence that is higher than the translucence of the exterior panel, the panels being joined together over at least a portion of their surfaces. Also disclosed is inspection of the sterilization wrap system for exterior panel breaches by looking for light passing through a panel facing the viewer.

wherein the panels are joined together over at least a portion of their surfaces, wherein the higher level of translucence of the interior panel compared to the exterior panel facilitates post-sterilization detection of breaches of the exterior panel when looking for light passing from the exterior panel of the wrap system through the interior panel of the wrap system after the wrap system is removed from a product that has been subjected to a sterilization cycle, wherein the difference in translucence between the interior panel and the exterior panel is 500 percent or more.

14. The system of claim 13 , wherein the plurality of bond points on the interior panel provide the interior panel with at least 15 percent higher translucence than locations on the permeable nonwoven material of the interior panel that are not bond points.

15. The system of claim 13 , wherein the exterior panel and the interior panel are a single sheet of permeable nonwoven material having barrier properties, the single sheet being folded over to form the exterior panel and the interior panel.

16. The system of claim 13 , wherein the exterior panel and the interior panel are independent sheets of material.
