10 is formed with windows of semi permeable material the friction enhancing material 22 can be applied to the remaining parts of the package without being applied to the windows fig3 and 4 illustrate an alternative form of packaging the instrument 18 is wrapped in a sheet or multiple sheets of csr central supply room wrap 24 a folded configuration 30 as shown in fig4 is held together by tape or sticker s 26 the tape or sticker 26 may be printed with a chemical indicator ink which changes color after exposure to the sterilizing gases friction enhancing material 28 is coated onto the csr wrap 24 in a pattern to allow penetration of sterilizing gases through the csr wrap 24 yet allow friction enhancement of the wrapped package 30 csr wrap is typically formed of a non woven polypropylene of single or laminated layers such as sms spunbond meltblown spunbond and is permeable to sterilizing vapors yet impermeable to potentially contaminating microorganisms it is used to wrap sterilization trays and also to wrap individual instruments for sterilization during a sterilization procedure the csr wrap 24 of the present invention carries the friction enhancing material 28 so that when wrapped around the instrument 18 to form the package 30 the package 30 has slip resistance from the friction enhancing material 28 the friction enhancing material 28 need only be applied to one side of the csr wrap 24 that side which will be on the outside of the finished package 30.
