A plasma field is formed when flammable gas and air are combined and combusted to form an intense blue flame.
Brief exposure to the energized particles within the flame affects the distribution and density of electrons on the substrate’s surface and polarizes surface molecules through oxidation. This method also deposits other functional chemical groups that further promote ink wetting and adhesion.

Flame-plasma treatment generates more heat than other treatment methods, but creates greater surface energies with a longer shelf life. An example of a flame treater for webs is Enercon’s Flame treatment is commonly used to process injection and blow-molded products because of the thickness, size, and shape of the parts.

Benefits of Flame Plasma

• Higher treatment levels.
• Longer lasting, uniform treatment.
• No ozone, solvent or UV emissions.
• Cost effective to operate.
• Efficient surface decontamination and polishing.
• Secure adhesion of decorations, inks, coatings, and labels.
