Corona Treater For Converting Lines
Converting applications such as Rotogravure /Flexographic printing solvent less/solvent based lamination, slitting, coating, Extrusion lamination /coating calls for treatment of verity of substrates at very high line speeds. Electro Tech Inc. Corona Treating Station comes with high definition ceramic electrodes which can treat metalized and non-metalized substrates at high line speeds.
The Corona surface treatment is essential in converting processes. A quality Corona is necessary to ensure that perfect laminating and printing result we all want to see when looking at products at the end of the production line. Therefore our Corona systems are not only designed for our converting customers, but also for our customers’ customers, as our Corona systems help you obtain a flawless and long lasting quality print and lamination.
Often our converting 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 printing press or laminator cannot run at full speed.
In converting processes our Corona systems are used for boosting already treated materials to create high adhesion ability and a fresh clean surface that is receptive to ink, glue and lacquering.
