Extrusion Line

Extrusion Line

Corona Treater on Blown Film and Cast Film Extrusion lines is essential in order to attain a perfect surface tension prior to the converting processes like printing/lamination/coating. Without Corona Treatment the extruded substrates will not allow further converting processes due to low surface tension

As a film manufacture you require reliable corona treatment equipments that can easily be maintained, be segment set-up and run production nonstop. These are key-points for a Corona treater on an extrusion line. The ElectroTech Industries Corona treaters are designed for our customers with the customer’s challenges in mind. We focus on equipments that will make your production run smoothly with uniform dyne level and no unplanned stops.

The ElectroTech Industries Corona treaters for extrusion line will provide higher dyne level on your materials due to the combination of ultra-efficient generators and superior treatment station design. The advanced electrode design eliminates fluctuations in dyne levels across the web width and furthermore guarantees no undesirable backside treatment.

The ElectroTech Industries treater stations are all made with the unique designs that allow the operators to perform segment set-up and maintenance within minutes – thereby providing maximum production time for your extrusion line.
