Corona treatment system is a very effective way to increase the surface tension of virtually any material. Surface treatment is required for plastic films/fabrics 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 substrate is now standard practice. 

Narrow web treater are mainly used for extrusion film plant for small to wide web width and low speed.

Eltech`s 3D corona treatment system is perfect solution to adhesion problems on injection, blow moulded or extruded parts of PE, PP, PET, nylon, vinyl, polystyrene, polycarbonate, PVC, fluorocarbons and all other types of thermoformed and thermoset plastics. 

3d jet corona can be used in a very flexible way, since a counter electrode is not needed. The discharge is ignited between a pair of electrodes inside the treatment tool and gets directed towards the substrate with a minor laminar air flow. 

This 3D corona treatment also eliminates grease, oils and other contaminants if any, which are most common adhesion retardants.3D surface-treating systems improve the bonding of inks, adhesives and coatings, allowing you to treat multiple surfaces and difficult configurations with remarkably consistent and convenient one-pass coverage.

What is Plasma ?
“PLASMA“ is a gas, which contains a big amount of electrical charges. In constast to normal gases,it is conductive although it appears electrically neutral to the outside. 
Ionisation of gas molecules for (nobel gases electrons from the molecules and atoms. Besides electrons, ions and normal neutral molecule fragments (radicals),which are chemically high reactive due to their unstable structure. This reactivity is used in many technical pretreatment before printing and gluing by oxidation of the surface of the ambient conditions using air as working excitation are used for this application

Information :

Eltech metallized treater assembly for high-speed corona treatment of conductive as well as non-conductive having smaller widths up to about 500 mm.

These treaters are an extension of suitable to treat conductive as well as nonconductive substrates such as aluminum foils, metallized films, multi layer films, paper, labels of various types etc.

Information :

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.

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 films/sheets.

Dynes/cm or Newtons/meter :
Dynes/cm or Newtons/meter is the unit of force in the centimeter-gram-second absolute system, the force which imparts an acceleration of 1 centimeter per second to a body having a mass of 1 gram.

Dynes Solution :
Dyne solutions have been used to measure wetting and predict adhesive potential of plastics and coated paperboard. This method is widely used to test the treatment level of plastic films intended for printing, laminating and coating. Test results are based on how varying surface tension solutions react when applied to a non-absorptive surface: If a given solution wets the surface, its dyne level is lower than the substrate's; if, instead, it rapidly forms beads, its dyne level exceeds that of the substrate. This method offers adequate precision and replicability for most capability studies, materials research and process control.
