In this work, atmospheric pressure, ambient air plasma was used for pre-treatment of clay coated paper before silicone coating as well as for post-treatment to prepare the release liner with low adhesion. As a plasma source “industrial corona” in roll-to-roll configuration was used for plasma treatment. The aim of the study was to evaluate the effect of plasma pre- and post-treatment time on adhesive properties of silicone layer sprayed on the paper. Plasma pre-treated paper was sprayed with silicone oil of different amounts using spray gun and subsequently plasma post-treated for defined repetition. Surface of silicone sprayed paper was analyzed by water contact angle measurement immediately after oil spraying procedure. The possible changes in morphology were characterized by scanning electron microscopy, chemical composition by X-ray photoelectron spectroscopy and the adhesion by measuring tape peel force. The silicone coated paper was characterized by increase of hydrophobicity and decrease of release factor with significant impact of plasma post-treatment.
