AbstractThis chapter describes a method of polymer treatment with the use of corona discharge. This is the most common industrial method to improve the wettability of nonabsorbent printing substrate before printing processes or to improve its properties before laminating or metalizing. This chapter describes treatment process and devices, as well as the factors that influence the effectiveness of modification. This chapter also characterizes the changes that occur on the upper layer of material, as a result of corona treatment, as well as the methods used to determine their characteristics. Based on the results of own research on polylactide (PLA) films, there is a presentation of application for surface topography examination, surface chemistry, and wettability to determine changes occurring in polymers during corona discharge and their impact on printability of this substrate. There is also a wide review of literature that was the basis for describing the changes resulting from treatment of polypropylene, polyethylene, polyethylene terephthalate, polyvinyl chloride, ethylene vinyl acetate, and PLA.
