Abstract

A method for sterilizing at least partly formed packages with electron beam irradiation in a packaging machine involves sterilizing each of at least two at least partially separate areas of the package by way of a respective electron beam sterilizing device, with each of the sterilizing devices being adapted to characteristics of each respective one of the two areas, and also performing a respective relative movement between the package and each of the electron beam sterilizing devices, which movements are adapted for the sterilization of each respective one of the two areas with the sterilizing devices.
