When treating paper with Corona you will get the benefits of cleaning the surface and removing any unwanted paper fibres that could create pin holes during the coating process. The treatment level lasts for a minimum of six months.
What is corona treatment in paper?
A corona treating system is designed to increase the surface energy of plastic films, foils and paper in order to allow improved wettability and adhesion of inks, coatings and adhesives. As a result, the materials treated will demonstrate improved printing and coating quality, and stronger lamination strength.
What is corona treatment machine?
Corona treatment is a surface modification technique that uses a corona dischargecorona dischargeA corona discharge is an electrical discharge caused by the ionization of a fluid such as air surrounding a conductor carrying a high voltage. A corona occurs at locations where the strength of the electric field (potential gradient) around a conductor exceeds the dielectric strength of the air.https://en.wikipedia.org › wiki › Corona_dischargeCorona discharge - Wikipedia 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.
What is plasma surface treatment?
Plasma surface treatment is a process that raises the surface energy of many materials so as to improve the bonding characteristics. Plasma technology is inclusive of many different purposes for surface treatment such as: cleaning, coating, printing, painting, and adhesive bonding.
How does corona surface treatment work?
A 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 receptive to adhesives, inks and coatings.
How does surface treatment work?
The treatment can improve wettability of the material by raising the material's surface energy and positively affect adhesive characteristics by creating bonding sites. The most advanced and successful methods of surface treatment are based on a principle of high voltage discharge in air.
How long does flame treatment last?
A Flame Treating process consists of exposing the surface to a suitable oxidizing flame for a period in the range 0.2 to 3.0 seconds.
How is corona treatment measured?
Corona treaters apply treatment measured in watt density to improve surface wettability. Generally speaking higher watt densities produce higher dyne levels, but the relationship is not always linear.
What is corona treated plastic?
Corona treatment (sometimes referred to as air plasma) is a surface modification technique that uses a low temperature corona dischargecorona dischargeA corona discharge is an electrical discharge caused by the ionization of a fluid such as air surrounding a conductor carrying a high voltage. A corona occurs at locations where the strength of the electric field (potential gradient) around a conductor exceeds the dielectric strength of the air.https://en.wikipedia.org › wiki › Corona_dischargeCorona discharge - Wikipedia plasma to impart changes in the properties of a surface. Corona treatment is a widely used surface treatment method in the plastic film, extrusion, and converting industries.
What is corona treatment on plastic?
Corona treatment is used to increase the surface energy of plastic and other materials for improved adhesion of inks, adhesives, and coatings. Corona treated materials feature higher printing and coating quality than materials that do not undergo this treatment.
What is corona discharge plastic?
The corona discharge is created when the high voltage and frequency electrical potential is applied to an electrode (ex. wire electrode or spring tip electrode). The corona discharge ionizes nearby atmosphere and when this is applied directly to the material it increases the surface tension of the material.
