Patent

CA 2154623

The invention relates to a process for the produc- tion of highly polar, scratch-resistant at least monoaxi- ally stretched polyolefin films by plasma pretreatment, characterized in that titanium is used as the cathode material, the applied voltage is in the range from 400 to 800 V and preferably in the range from 500 to 700 V, the voltage being an a.c. voltage or a pulsating d.c. vol- tage, and in that the treatment of the film is carried out under pressures of 0.01 to 0.5 mbar and preferably 0.03 to 0.42 mbar in an oxygen atmosphere or in an atmosphere containing non-metal oxides and mixtures thereof with noble gases.
