Corona Treater Silicone Sleeve
SEVITSIL Corona treatment was introduced into the industrial sector due to its ability to treat metal and plastic surfaces, imparting adhesive characteristics that allowed for easy printing or bonding on a range of surfaces.
The printing industry is most interested in corona treatment for dependable and efficient printing on plastic substrates. The surface of the material becomes significantly more impressible to adhesives, inks, and coatings after being treated with a high-frequency corona discharge.
Corona Treater Silicone Sleeve is made from refined silicone rubber, it is resistant to high voltage, is flame retardant, and produces a uniform corona spark under high voltage. Used for electric spark treatment of plastic films, plastic woven bags, etc., to activate the surface or make micro holes for easy printing and coloring.
Applicable to all kinds of corona treatment sparking machine casing, used as a high-voltage electrode, hose and high-voltage output line sheath tube.
It is a high-voltage corona and electrode roller for corona treatment equipment BOPP, COPP, POPE and other wide film production lines.
