To achieve a brilliant blemish-free metallization coating, raw substrates must be free of surface contamination, such as migrating additives, dirt, dust, and other contaminants. Surface treatment can effectively removes organic debris from the surfaces of packaging materials such as films to retain their metallization layer and provide barrier properties at designed and acceptable level.
Eltech Corona Treater system creates powerful bonding for printing, painting, coating,laminating and adhesion applications. Our technology is uniquely designed to treat 2-dimensional films, as well as many other applications requiring Improved surface energy and long-lasting activation.
Corona treatment system increases the surface tension of any material respective to inks by inducing molecular changes in the surface of the material. This is done by exposing the air at the material's surface to a high-voltage electrical discharge - Corona.
