SURFACTANT TREATMENT FOR STERILIZATION WRAPPING WITH REDUCED OCCURRENCE OF WET PACKAGES AFTER STEAM STERILIZATION Russian patent published in 2019 - IPC A61L2/07 D06M15/53 

FIELD: medicine.

SUBSTANCE: group of inventions discloses a method for reducing the frequency of developing wet packages of articles after sterilization, as well as a sterilized wrapper subjected to an electretting treatment for wrapping articles in a package. Method involves obtaining a sterilable wrapper from a non-woven material, applying a surface-active agent containing a surfactant, wherein the surfactant consists of carbon, hydrogen and oxygen atoms, on the nonwoven material in amount of 0.1 to 1.5 wt. % in terms of sterilization wrap dry mass, drying, wrapping articles to be sterilized to produce articles package, and steam sterilization of article wrapped package, wherein the method further includes a step for electrifying treatment of the sterilization wrapper before or after the step of applying the surfactant and drying the sterilization wrapper.
