The effect of surface oxyfluorination on the low-density polyethylene (LDPE) film was studied in terms of surface functionality and surface energetics of the film surface, which can be attributed to the improving of the adhesion. The growing of functional groups and surface free energy were confirmed by FTIR-ATR, XPS, and contact angle method. Adhesion strengths of the oxyfluorinated LDPE film were investigated by T-peel test. As a result, the oxyfluorinated LDPE film led to an increase of total surface free energy, mainly due to the increase in its specific (or polar) component, resulting in increasing the adhesion properties. It was then revealed that the oxyfluorinated LDPE film played an important role in improving the adhesion of the LDPE film. A direct linear relationship is shown between surface free energy and the adhesion strengths for this work.
