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.
Solvent Printing Ink Adhesion & Corona Treating
The use of corona treating to improve adhesion on water based ink formulations is widely accepted as a best practice. However printers who use solvent inks may not realize that there is much to be gained from using a corona treater for solvent printing applications.
