The purpose of corona treatment is to optimise the adhesion properties on polymer-based materials. The low surface energy of polymer-based substrates often leads to poor adhesion of inks and coatings which by nature present significantly high surface energies. To obtain optimum adhesion, it is crucial that the surface energy of the substrate is equal or higher than the surface energy of the material to be applied to the polymer

WebTEC is a self-contained Corona Treater for treatment of paper, plastic, metallised film and foil.

In a special version WebTEC treats materials like expanded foam and corrugated board, too.

The compact design enables the equipment to be easily installed in new or existing extrusion, printing, coating and laminating lines. The system includes a high frequency Corona Generator, high voltage transformers, and an ozone filter system.
