However, the low surface free energy hinders processes such as printing and labelling, where improved wettability and good adhesion are needed. BOPP surface activation was tested using two different low-temperature plasma sources operating in ambient air and capable of in-line operating. The volume dielectric barrier discharge (VDBD) and diffuse coplanar surface barrier discharge (DCSBD) were applied to improve the wettability and adhesion of several seconds (1-10 s) treated surface. The changes in morphology and surface chemistry were analysed by SEM, AFM, WCA, SFE and XPS. The adhesion was estimated by a peel force test, and the ageing of the treatment was monitored for a month. Both plasma sources ensured the stable improvement of surface properties acquired mostly by introducing polar (oxygen-containing) groups onto the surface. However, the VDBD treatment induced structural changes causing undesirable haze and loss of transparency of BOPP foil, which was not observed in the case of DCSBD treatment. ER -
