Tips: corona treatment on printing machines

One of the converting processes is printing films or other webs of flexible material. Further corona treatment is often necessary, even though materials are used which have already been corona treated during manufacture.
However, long periods of storage mean that the surface tension is no longer enough to guarantee satisfactory adhesion of the ink.
This process requires a surface tension of at least 38-40 dyne/cm for printing inks containing solvents, and 44-46 dyne/cm for water-based printing inks which are being used more and more in the printing industry for environmental reasons. If the surface tension falls below these values it is necessary to refresh the treatment before printing to ensure good adhesion between the film and the ink.
