Sheet Corona Treatment

Eltech 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.



Applications of Sheet Corona Treater

Sheet Corona treatment system readily solve surface adhesion problems for a wide variety of products like : 

PVC, PP, LD, Foam, Flex, metallized polyester, PE, OPP and other high-low density plastic materials should particularly be Corona treated to enhance the quality of the final product



 Sheet Corona Treater

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, metallized polyester, PE, OPP and other high-low density plastic materials should particularly be Corona treated to enhance the quality of the final product.
