A method and apparatus for manufacturing medical paper for medical sterilization packaging, medical paper and medical sterilization packaging are disclosed. A paper web is formed of fibrous substrate comprising cellulosic fibers and optionally synthetic fibers, with opposite first and second sides. On-line with the forming of the paper web, reinforcing material is applied on the first side and pressed into structure of the paper web such that delamination resistance of the structure is increased. Sealing material is applied on the second side of the paper web on-line with the forming of the paper web.

A self-contained web cleaning apparatus is disclosed herein. The self-contained web cleaning apparatus includes a vacuum assembly, the vacuum assembly including a vacuum source, the vacuum source configured to create a vacuum for removing particulate matter from a continuous web of material; and at least one particulate extraction device fluidly coupled to the vacuum assembly, the at least one particulate extraction device defining a slot therein through which the particulate matter from the continuous web of material is extracted. The vacuum assembly and the at least one particulate extraction device are disposed within a self-contained structure without any connections to an external vacuum source located outside of the self-contained web cleaning apparatus.
