Corona treatment system is a very effective way to increase the surface tension of virtually any material. Surface treatment is required for plastic filmsfabrics whose normal surface tension is not sufficiently high to permit good wetting by flexo graphic inks. Corona treatment system increases the surface tension of the fabrics respective to inks by inducing molecular changes in the surface of the films. This is done by exposing the air at the material's surface to a high-voltage electrical discharge - a corona. Corona discharge treatment at atmospheric pressure for improving adhesion of various polymer substract is now standard practice. As shown in the diagram the fabric is passed from free roller through the airgap between multisegmented electrode and the silicon roller which generates continuous shower of ionised air called as CORONA.The electerode and dielectric cover on the roller serves as the electric connection to the stream of ionized air in the airgap.

Water-based and UV inks printed on plastic films and other substrates create a need for the substrate to be treated prior to printing. Corona treating is a very effective way to increase the adhesion of virtually any plastic material. Corona treatment increases the surface tension of the Sheet Fabrics receptive to inks by inducing molecular changes in the surface of the filmssheets.

Corona Treatment is a process of high speed oxidation which creates polar molecules on the film surface. The energy of the corona will break the bonds of the atomic structure of the substrate. The oxygen rich ozone developed by the corona discharge readily fills the open valancies which create a charge surface thus improving the surface characteristics. The Treated surface tends to go back to it's original dyne level after a certain period of time. Zero Speed System: In case the Guide or Main Roller stops moving , the Generator Trips.

Eltech sheet corona treater is widely used to treat PP,PVC and metallised polyester laminated sheets to increase surface tension and gives better printing and adhesion. Water-based and UV inks printed on plastic films and other substrates create a need for the substrate to be treated prior to printing. Conventional method of roll to roll treatment is standard practice, but in Offset, Sheet corona treatment is required to increase surface tension or improve the printability. Some substrates are corona-treated when they are manufactured. Many of these substrates require a surface energy boost to match a particular ink or coating. This is done with corona pretreaters on the press just prior to the coating application point. PVC, PP, LD, Foam, Flex, metallized polyester, PE, OPP and other high-low density plastic materials should particularly be Corona treated to enhance the quality of the final product.

    Nowadays a lot of substrate require surface  treatment for 3 dimensional substrates Presently the industry uses expensive treatment solutions which account for higher consumables and operating costs. Eltech through its R&Dhas indigeneously developed a treatment system to provide a solution to this problem.Thankfully it now possible to use this new technology.  PLASMA ION can effectively treat conductive as well as non conductive substrates. Plus it  consists of a High frequency power supply with an inbuilt  transformer and a plasma  nozzle . The nozzle comes  in various  shapes for effective treatment as per the requirement of the application. The nozzle can either be used manually or fitted on a robotic arm. In some applications more than 1 nozzle may be required .In such a case, ELTECH offers multiple plasma treating heads. This technology is suitable for high speed online as well as offline surface treatment and is extremely safe, cost effective and easy to use. Moreover it is a very clean and energy efficient technology since its operation requires dry compressed air which is  freely available.

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.
