ElectroTech Industries sheet corona treater is widely used to treat PP, PVC and metallised polyester laminated sheets to increase surface tension and gives 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. Conventional method of roll to roll treatment is standard practice, but in offset, Sheet corona treatment is required to increase surface tension or improve the 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 pretreaters on the press just prior to the coating application point. PVC, PP, LD, Foam, Flex, metalized polyester, PE, OPP and other high-low density plastic materials should particularly be Corona treated to enhance the quality of the final product. ElectroTech Industries Sheet Corona treaters offer sheet converters the in-house ability to treat a wide variety of non-porous polymer based materials and synthetic papers. These material types have inert and low surface energy preventing inks from properly adhering. In-line sheet treatment ensures successful printing by raising the substrate's surface energy to allow inks to properly wet-out Pre-treatment is ideal for any sheet printing process including lithography, UV, EB and Screen Printing. Common materials that require treatment include Polystyrene (PS), Polyvinylchloride (PVC), Polyethylene (PE), Polypropylene (PP), Polycarbonate (PC), and Polyester (PL).

The Corona Treatment is essential in label printing. When the label is made from plastic substrate the ink tends to become blemished due to its inability to bond to the plastic. This problem occurs because the surface energy of the plastic is insufficient to form a proper bond. Often, our customers discover that batches of incoming material have low dyne level (surface adhesion) or that the dyne level of the material on stock has decreased due to heat or humidity. Due to the low dyne level the narrow printing press cannot run at full speed. As a consequence the ElectroTech Industries Corona systems are used for boosting already treated materials to create high adhesion ability. A common problem in the narrow web industry is the necessity for using top coated materials which have been chemically altered in order to obtain a high surface adhesion for inks. The top coated materials are more expensive to purchase than regular materials. By adding an ElectroTech Industries Corona treater to your narrow web press, you will often eliminate the need for using top-coated materials and thereby decrease production costs significantly The new generation label press demands compact and efficient corona treatment systems for treatment of variety of substrates at high line speeds. ElectroTech Industries Narrow Web Push-Pull type Corona Treating Station is specially designed keeping the compactness, operator friendliness and efficiency in mind.
