Corona treatment is a widely used surface treatment method in the plastic film, extrusion, and converting industries. [1] The corona treatment was invented by the Danish engineer Verner Eisby in 1951. Eisby had been asked by one of his customers if he could find a solution which would make it possible to print on plastic.

Corona treating increases the surface energy of plastic films, foils and paper to improve wettability and adhesion of inks, coatings and adhesives. Treating works best when a substrate is treated at the time of extrusion and in-line prior to converting.

Corona treaters increase the surface energy of films, foils, and paper to improve wettability and adhesion of inks, coatings and adhesives. Ask Enercon to specify a custom surface treating solution for your project and you’ll be tapping into a world of experience.

To be more precise, corona treatment is used to increase a material’s surface tension in an effective way. By treating the material with a high frequency corona discharge, its surface becomes much more impressible to adhesives, inks and coatings. The material that needs treatment is revealed in front of the electronic corona discharge.

Put simply, corona treatment is a technology which alters the surface of plastics and other materials so that they can be printed on. Due to the nature of these materials, they do not easily bond with inks, coatings, adhesives, and other printing materials.

Baldwin’s flagship brand Ahlbrandt ® is a world renowned manufacturer of corona treatment systems for printing and industrial applications such as film and sheet extrusion, and textiles. Our systems offer key features and benefits that set them apart from the competition by providing ease of service and reliability that is simply unmatched.

Corona treatment is a surface modification technique that uses a low temperature corona discharge plasma to impart changes in the properties of a surface. Corona treatment has been used to either improve the print fastness of a polymer film or to perforate the film (see Section 8.2.2: Roughening).

Corona treatment is a surface modification technique that uses a corona discharge to impart changes in the properties of a surface. Treating the surface a material/an object with a Corona treater will ensure bonding with printing inks, coatings, and adhesives.

Corona treatment increases the bonding characteristics of a substrate by increasing the surface energy (dyne level). Many plastic films have an inherently low surface energy which effects particle adhesion to the substrate. Corona treatment is the most common surface treatment to increase polymer dyne levels in the converting industry.
