Components of Corona Treater
Corona Treater Power Supply
The corona treatment station power supply consists of a high frequency generator and a high voltage output transformer. The supply takes power, converts it to a higher frequency and voltage, and provides the treater station the power needed to generate a corona discharge. Power supplies range in power rating from 500 watts to 30 kilowatts, with the exact wattage needed depending on the application.
Corona Treatment Machine
The treatment station is where the corona treatment process actually happens.
Here, an electrical discharge supplied by the power supply passes from a high voltage electrode to a ground electrode. The bare or covered ground electrode is in what is known as the “ground roll.” This electrode spans the length of the ground roll. It receives the high voltage required to create the ionized air that makes corona treatment work. The material being treated then passes through the ionized air, altering the surface energy and allowing for easier printing, laminating, and more.
Working Process of Corona Treater
The corona treater process works by applying a high voltage electric discharge to an electrode across an air gap. This creates what is known as a “corona discharge.” This discharge ionizes the air around the material, causing changes to it on a molecular level and increasing the material's surface energy.
The corona treater process occurs in a matter of seconds to minutes. A number of theories exist as to what is happening to the material on a molecular level, including oxidation and micropitting. Although these changes are invisible to the naked eye, they significantly increase the ability of inks and coatings to adhere to the material.
Applications of Corona Treater
Printing & Labeling
Flexographic, rotogravure, and digital printers use corona treater to achieve reliable ink adhesion on PE, PP, PET, and other film substrates. Eliminates print defects caused by low surface energy.
Coating & Laminating
Extrusion coaters and laminators rely on corona treater to create strong bonds between polymer coatings, adhesives, and multi-layer film structures at high line speeds.
Blown & Cast Film Extrusion
Film manufacturers integrate corona treaters directly at the extrusion line to deliver pretreated PE, PP, and specialty films — ensuring downstream converting processes start with adequate surface energy.
Narrow Web
Tag and label presses demand precision corona treater in compact spaces. Corona treaters integrate seamlessly into any press configuration for consistent ink adhesion on flexible substrates.
Research & Development
Lab-scale corona treaters that replicate production watt densities for substrate testing and process validation. Determine optimal treatment parameters before committing to full-line equipment.
Specialty & Custom
Ultra-thin substrates and unique material requirements. Custom-engineered corona treater solutions for applications that don't fit a standard configuration.
Corona Treater Works on Nearly Any Material
Flexible Films
PE, PP, PET, nylon, BOPP, and specialty films for packaging, labeling, and industrial applications.
Rigid Plastics
Sheets and corrugated plastics requiring surface treatment before printing, coating, or bonding.
Paper & Paperboard
Coated and uncoated papers and specialty paper substrates for enhanced ink and coating adhesion.
Foils & Metals
Aluminum foil, metallized films, and thin-gauge metal substrates for packaging and industrial converting.
Nonwovens & Textiles
Spunbond, meltblown, and woven fabrics for medical, hygiene, filtration, and industrial applications.
Rubber & Elastomers
