Corona treatment is high voltage, high frequency electrical discharge that increases bonding capacity of plastic surface.
Corona treatment discharged between ground electrode and high voltage electrode is also know as Corona Discharge. Corona treater is widely used in plastic packaging industries for increasing surface tension of plastic films before printing, lamination and coating. This treatment is measured by Dynes solutions where unit of surface tension is measured by Dynes/CM.
Yash Electronics Corona Treaters are user friendly and high efficiency generators that provide better treatment at less power.
For conductive films treatment need BareRoller Corona Treater. In BareRoller Corona Treater Roller is bare (without Silicon Sleeve).
High voltage Electrode Roller is covered with Silicon Sleeve. Bare Roller Corona Treater is used in Converting Application and Metallised Films.
