Abstract
Method of sterilizing a packaging material with a sterilizing agent in liquid form. The packaging material is discharged in order to eliminate electrostatic surface charged on the packaging material, after which the packaging material is wetted with the sterilizing agent which is applied in an electrostatically charged form to those areas of the packaging material which are to be sterilized. The packaging material with the sterilizing agent, which coalesces to a thin, homogeneous film, is finally heated to drive away the sterilizing agent from the sterilized packaging material.
