Corona treatment and Plasma treatment of BoPET films

+++++++

Dear sirs,

I would like to understand the conceptual difference for Corona treated and Plasma treated BoPET film. If polarity generation is the vital criteria for good adhesion than untreated PET (being Polar) should be at par with Corona treated PET films. How do you suggest big difference between Corona treated PET vs Plasms treated PET.
