Narrow Web and Label

The purpose of corona surface treatment of polymer based materials is to increase surface wettability through electrical discharge. The low surface energy of polymer based substrates often leads to poor adhesion of inks, glues and coatings. To obtain optimum adhesion it is necessary to increase the surface energy of the substrate to just above that of the material to be applied. Surface treatment with corona results in good wetting of the material over the surface of the substrate and so improves adhesion.

This type of corona treating system can be supplied to treat either one or both sides of the web and can accommodate a wide range of widths. The narrow web corona treater is designed for the pre-treatment of conductive and non-conductive narrow webs.


• Compact design & construction.
• Easily fitted to new or existing production lines or presses.
• Ceramic electrode elements for uniform surface treatment.
• Good accessibility for initial web thread-up.
• Interchangeable electrode system.
• Available for single and double sided treatment.
• Idler rollers included.
• Stainless steel backing roller.
• All units conform to CE regulations and carry CE mark.
• Standard mountings available for most narrow web presses.

Our very compact narrow web treater combines simple operation with superb performance. The high voltage transformer is mounted directly on to the treating station, completely removing the need for trailing high voltage cables.
