Corona Surface Treatments

BW Converting's Baldwin CoronaFlex surface treatment system improves the adhesion of inks, coatings and adhesives to a wide range of substrates. By creating plasma to enhance the surface energy of materials, the Baldwin CoronaFlex ensures optimal print quality and adhesion, particularly for non-porous materials like plastics. While the Baldwin CoronaFlex is for thicker substrates, like foam tape, there is also the Baldwin CoronaSlim for narrow web printing and the Baldwin CoronaPure for wide web printing. With precise, adjustable settings, this system helps you achieve reliable and high-quality results across various printing applications.
