Corona Treatment is a well known process used in the extrusion and converting industries. Corona treater electrodes, roll coverings and power supplies can be optimized to meet the challenges of printing, coating, laminating, blown film, and cast film applications. Below is a sampling of typical applications where corona treatment is used to promote adhesion.
Embossed film corona treating design minimizes pinhole potential
Embossed films have peaks and valleys that create a special set of circumstances when it comes to interacting with corona. To minimize the chance of pinholing Enercon has developed a special ceramic electrode treater station design that minimizes filamentary discharges and also expertly manages the films’ exposure to watt density per square inch without sacrificing treatment levels.
