Abstract
A medical packaging substrate that is able to withstand ozone sterilization without generating a significant amount of odor and without undergoing a substantial degradation in strength is provided. This is accomplished by selectively controlling the components of the medical packaging substrate to optimize ozone compatibility. For example, the medical packaging substrate may be formed from a cellulosic fibrous material having a pH of about 7.0 or more. The present inventor has surprisingly discovered that such high pH values may allow the substrate to be effectively sterilized with ozone without generating substantial amounts of odor. In addition, a wet-strength agent and/or binder composition may also be selected that optimize the strength properties of the substrate without resulting in substantial odor.
