Corona treater is an equipment that is designed for elevating the surface energy of several products, like plastic films, foils and papers. It is used basically for improving the properties, such as wettability and adhesion of products, like adhesives, coatings and inks which will give better quality printing, coating and laminating strength. It uses a technique for surface modification to change surface properties. Hence a corona treater will help in surface modification for improving the surface for better use. However the treater can use the following ways of surface treatment like oxidation, micro-pitting, the electric effect etc.
