General Introduction:
Sheet corona treater is widely used to treat PP, PVC, and metalized polyester laminated sheets to increase surface tension and give better printing and adhesion.
Water-based and UV inks printed on plastic films and other substrates create a need for the substrate to be treated prior to printing.
Corona treating is a very effective way to increase the adhesion of virtually any plastic material. Corona treatment increases the surface tension of the Sheet / Fabrics receptive to inks by inducing molecular changes in the surface of the films/sheets.
The conventional method of roll-to-roll treatment is standard practice, but in Offset, Sheet corona treatment is required to increase surface tension or improve printability. Some substrates are corona-treated when they are manufactured. Many of these substrates require a surface energy boost to match a particular ink or coating. This is done with corona pretreated on the press just prior to the coating application point.
