Plastic pouch roll require batch printing and price printing before material filling in pouch,pouch roll has to be treated before printing for better adhesion of ink , corona treatment alters the surface of the film and increases Dynes value. More receptive of inks better bonding, long lasting Printing.
Eltech Corona treater system creates powerful bonding for printing, painting, coating,laminating and adhesion applications. Our technology is uniquely designed to treat 2-dimensional films, as well as many other applications requiring Improved surface energy and long-lasting activation.
The Corona treatment system is a very effective way to increase the surface tension of virtually any material. Surface treatment is required for plastic films whose normal surface tension is not sufficiently high to permit good wetting by flexo graphic inks. Corona treatment system increases the surface tension of any plastic material 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 - Corona.
Corona discharge treatment at atmospheric pressure for improving adhesion of various polymer substrates is now standard practice.
Our corona treater machines give efficient prompt surface improvement for printing on all types of laminates like, Foil, Paper, LDPE, HDPE, PVC, etc.
The Batch Coding application for Winder Re-winder Machine is coupled beautifully & synchronized well with our eltech’s corona treater machine.
