Corona Treatment
Corona treatment is a surface modification technique by which an electrical discharge in air is applied to materials such as polypropylene, polyethylene and fluoropolymers which have chemically inert and nonporous (or porous) surfaces with low surface tensions, and which are typically non-receptive to bonding with printing inks, coatings, and adhesives.
ITW Pillar Technologies offers contract/toll corona treatment of many web materials using single dielectric (bare or covered roll) or dual dielectric VERSATreat™ technologies.
