Claim Text:
1. A multi-layer non-woven sterilizable packaging material comprising: a top layer comprising nanofibrillated lyocell fibers; and a bottom layer comprising a blend of: (a) microfibers; (b) synthetic fibers having a flat, generally rectangular cross-section with at least one dimension that is generally flat and a length of about 5 to 10 millimeters, the synthetic fibers having a flat, generally rectangular cross-section are ribbon-like fibers that have split apart from splittable conjugated fibers, the splittable conjugated fibers comprising a PET component and a Nylon component, such that a first of the ribbon-like fibers that have split apart from the splittable conjugated fibers consists of the PET component and a second of the ribbon-like fibers that have split apart from the splittable conjugated fibers consists of the Nylon component; (c) binder fibers; (d) a first polymeric fiber having a first linear density and a first length; and (e) a second polymeric fiber having a second linear density and a second length both greater than the first linear density and first length of the first polymeric fiber; the packaging material having a Log Reduction Value greater than 2.
