Eltech Sheet Corona treater
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 Printing / coating application point.
Corona treatment should be applied to plastic surfaces before lamination, glue coating or printing to prevent shedding of the ink or coating ensuring the best quality is achieved.
PVC, PP, LD, Foam, Flex, metallised polyester, PE, OPP and other high-low density plastic materials should particularly be Corona treated to enhance the quality of the final product.
