High-Performance Corona Treatment System for Plastic Film and Industrial Applications
Description
🌟 Product Overview
The Corona Treatment System is an advanced surface treatment solution designed to enhance adhesion on plastic films, paper, and composite materials before printing, coating, or laminating. Using high-frequency electrical discharge, this Corona Treater modifies the material surface to improve wettability and ink bonding performance.
Widely used in blown film extrusion, flexographic printing, lamination, and coating machines, our Corona Treatment Equipment ensures consistent treatment results, high efficiency, and long-term stability.
As a leading corona treatment system manufacturer, we provide fully customizable systems to meet the specific requirements of film producers, printing plants, and packaging converters worldwide.
The Corona Treatment System is an essential surface pretreatment device designed to improve the adhesion of inks, coatings, and adhesives on plastic films, paper, and metalized substrates.
It is widely used in high-speed blown film lines, spray bonding, extrusion coating, printing, lamination, glue spreading, coating, box-pasting, and other specialized industries that require excellent surface activation performance.
