Process and apparatus for eliminating residual monomers in packaging film by electron bombardment

摘要

The present invention relates to a process for eliminating residual monomers in packaging films by electron bombardment, in which the bombardment is carried out with low-energy electron beams in the range from 150 to 300 kV accelerating voltage using an electron gun having a large-area electron exit window. The apparatus for carrying out the process specified above comprises an electron gun for generating low-energy electron beams in the range from 150 to 300 kV accelerating voltage having a large-area electron exit window and a drum which is arranged in front of the electron exit window and on which the film material to be bombarded is taken past the electron-beam window.
