Corona discharge is widely used as a good surface pretreatment method for polymer materials. In this work, the attenuated total reflectance Fourier transform infrared spectrometry (ATR-FTIR), X-ray photoelectron spectroscopy (XPS), scanning electronic microscopy (SEM), and atomic force microscopy (AFM) were used to investigate the behavior of biaxially oriented polypropylene (BOPP) film treated by corona discharge. The possibly involved chemical reactions during the corona treatment process under atmosphere components were systematically summarized. This work lays a theoretical basis for improving the performance of BOPP films and expanding their application fields.
