There is provided an improved sterilization wrap and a method for using the improved sterilization wrap to sterilize an article. The wrap is made of at least one sheet, and preferably two sheets, of sterilization material and in some embodiments, includes an additional sheet which may be made of an absorbent material. The sheet of absorbent material may have a smaller perimeter than at least one sheet of sterilization material. One side of at least one sheet of sterilization material includes a central portion. The absorbent material may be attached to the central portion of at least one sheet of sterilization material. The article to be sterilized is placed on the sterilization wrap and is then wrapped. The absorbent material provides sterility protection for the article in addition to the at least one sheet of sterilization material and also wicks moisture away from the article after sterilization has taken place. A visual indicator may be provided to indicate whether or not the article has been exposed to adequate sterilization conditions.

1. A sterilization wrap for wrapping an article to be sterilized comprising: a first sheet of sterilization material, the first sheet having an outer periphery and a central portion, wherein the first sheet is made of spunbonded-meltblown-spunbonded material (SMS);a sheet of reinforcement material that is bonded to the central portion of the first sheet and adapted to receive the article to be sterilized, wherein the perimeter of the sheet of reinforcement material is smaller than the perimeter of the first sheet, wherein the sheet of reinforcement material is made of spunbonded-meltblown-spunbonded material (SMS) of equal or higher basis weight than the SMS of the first sheet, and wherein the sheet of reinforcement material has a different color than the first sheet; anda second sheet of sterilization material made of SMS and bonded to outer periphery of the first sheet;wherein the sterilization wrap is configured such that when the article to be sterilized is wrapped by the sterilization wrap, both the bottom and the sides of the article to be sterilized is covered by the sheet of reinforcement material and the top of the article to be sterilized is covered by the first sheet. 2. The sterilization wrap as set forth in claim 1, wherein each of said first and second sheets of sterilization material includes four edges about their peripheries; said four edges of said first sheet of sterilization material being bonded to said four edges of said second sheet of sterilization material. 3. The sterilization wrap as set forth in claim 1, wherein the perimeter of said sheet of reinforcement material is at least 25% less than the perimeter of said first sheet of sterilization material. 4. The sterilization wrap as set forth in claim 1, wherein said first sheet of sterilization material has two sides; one side of said two sides of said first sheet of sterilization material having a central portion; said sheet of reinforcement material bonded to said first sheet of sterilization material at said central portion of said one side. 5. The sterilization wrap as set forth in claim 1, wherein said sheet of reinforcement material is bonded to said first sheet of sterilization material by glue. 6. The sterilization wrap as set forth in claim 1, wherein said sheet of reinforcement material is bonded to said first sheet of sterilization material by heat and pressure. 7. The sterilization wrap as set forth in claim 1, further including a chemical visual indicator; said chemical visual indicator being in one visual state prior to exposure to sterilant and being in another visual state after exposure to sterilant; said chemical visual indicator being attached to said sterilization wrap so as to indicate whether or not the article to be sterilized has been exposed to adequate sterilization conditions. 8. The sterilization wrap as set forth in claim 7, wherein said chemical visual indicator is attached to said first sheet of sterilization material. 9. The sterilization wrap as set forth in claim 7, wherein said chemical visual indicator changes color after having been exposed to steam. 10. The sterilization wrap as set forth in claim 7, wherein said chemical visual indicator meets the requirements of ISO 11140-1. 11. A method for sterilizing art article comprising the steps of: providing an article to be sterilized;providing a sterilization wrap which comprises: a first sheet of sterilization material, the first sheet having an outer periphery and a central portion, wherein the first sheet is made of spunbonded-meltblown-spunbonded material (SMS);a sheet of reinforcement material that is bonded to the central portion of the first sheet and adapted to receive the article to be sterilized, wherein the perimeter of the sheet of reinforcement material is smaller than the perimeter of the first sheet, wherein the sheet of reinforcement material is made of spunbonded-meltblown-spunbonded material (SMS) of equal or higher basis weight than the SMS of the first sheet, and wherein the sheet of reinforcement material has a different color than the first sheet; anda second sheet of sterilization material made of SMS and bonded to outer periphery of the first sheet;wrapping the article to be sterilized with the sterilization wrap such that both the bottom and the sides of the article to be sterilized is covered by the sheet of reinforcement material and the top of the article to be sterilized is covered by the first sheet; andapplying sterilant to the wrapped article. 12. The method for sterilizing an article as set forth in claim 11, wherein each of said first and second sheets of sterilization material includes four edges about their peripheries; said four edges of said first sheet of sterilization material being bonded to said four edges of said second sheet of sterilization material. 13. The method as set forth in claim 11, wherein the perimeter of said sheet of reinforcement material is at least 25% less than the perimeter of said first sheet of sterilization material. 14. The method as set forth in claim 11, wherein said first sheet of sterilization material has two sides; one side of said two sides of said first sheet of sterilization material having a central portion; said sheet of reinforcement material bonded to said first sheet of sterilization material at said central portion of said one side. 15. The method as set forth in claim 11, wherein said sheet of reinforcement material is bonded to said first sheet of sterilization material by heat and pressure. 16. The method as set forth in claim 11, wherein the sterilization wrap further includes a chemical visual indicator; said chemical visual ndicator being in one visual state prior to exposure to sterilant and being in another visual state after exposure to sterilant; said chemical visual indicator being attached to said sterilization wrap so as to indicate whether or not the article to be sterilized has been exposed to adequate sterilization conditions. 17. The method as set forth in claim 16, wherein said chemical visual indicator is attached to said sheet of first sheet of sterilization material. 18. The method as set forth in claim 16, wherein said chemical visual indicator changes color after having been exposed to steam. 19. The method as set forth in claim 16, wherein said chemical visual indicator meets the requirements of ISO 11140-1.
