Plastics with chemically inert and nonporous surfaces have low surface tensions making them unreceptive to bonding with inks, coatings and adhesives. Plasma treatment of plastics is used in the automotive, medical, packaging, assembly and many other industries.
Flexographic, gravure, ink-jet, screen, and pad printing applications require surfaces to meet minimum adhesion requirements. Understanding how surface treating systems prepare surfaces for water based and solvent based inks is key to successful ink adhesion.
Flexible packaging converters utilizing aqueous inks on polyester-based structures may experience improvements in ink adhesion by employing APT-based surface treatment systems. Learn more about atmospheric plasma treatment for flexible packaging.
In-line Plasma & Flame treatment are recognized as green technologies in the automotive industry as they help reduce cost and improve performance without the need for hazardous primers and chemicals.
Atmospheric plasma treatment promotes the bonding of aqueous inks, coatings and adhesives to provide excellent abrasion and smudge resistance. Enabling the use of inkjet markings increase throughput for wire and cable markers.
Atmospheric plasma assist systems clean, etch and functionalize folding carton surfaces to improve bond strength, increase line speeds and improve quality. Commonly used materials include polycoated, polybacked, virgin kraft board, specially coated materials, UV lacquered surfaces and recyclable materials. Some users of plasma treaters have been able to reduce adhesive costs by replacing hot melt glue with cold set adhesives in their folder gluers.
Plasma3 technology envelops and cleans the fibers of woven and nonwoven structures to significantly enhance their wettability, printability, dyeability and fiber capillarity (faster dye/ink uptake). Significant improvements in the ink adhesion, dyeing depth and colorfastness of textile webs, yarns and filaments have been achieved, along with the pre-sterilization of various medical-grade textiles. Learn more about plasma treating nonwoven textiles.
Microporous membrane materials such as battery separators which are treated by Plasma3™ have enhanced hydrophilicity and wickability, significantly improving the efficiency of the battery cell.
Plasma3™ provides a surface cleaning and activation solution for roll to roll photovoltaic applications. Atmospheric plasma surface treatment systems provide an in-line solution to economically improve adhesion for films, foils and sheets. It is ideal for use prior to coating, laminating and deposition processes. It is highly effective at treating a wide range of substrates including Aluminum, Copper, Stainless Steel, EVA Film, ITO Film, PEN Film, PET Film, Polyimide Film and Glass.

Flexible / Rigid Flex Circuitry
Plasma3™ cleans and functionalizes polyester, polyimide, copper and stainless steel layer components by combining ion and electron bombardment with reactive plasma chemistries. Activation of Plasma3™ gas chemistries combined with UV energy volatilizes and removes surface contaminants while simultaneously raising surface energy and modifying surface functional groups.
Cleans copper and stainless steel layer components of PCBs before liquid photoresist coating with ion and electron bombardment after the etching process. Plasma3 is removing rolling oils and other surface contaminations from aluminium and steel foils prior to slitting and rewinding. Activation of Plasma3™ gas chemistries combined with UV energy to create a chemical reaction with the surface contaminants, resulting in their volatilization and removal. Learn more about plasma treatment for PCBs.
Plasma3™ is removing printed conductive ink or stamped foil debris from the chip site for clean contact with the antennae leads. It also functionalizes the entire surface of the RFID inlay for adhesion to film and/or paper label layers. Learn more about plasma treatment for RFID tags.
Uniquely conductive to treating these materials, Plasma3 is increasing the surface tension of closed cell foams to improve lamination adhesion to films without pinholing.
Introducing a new route to high performance surfaces
Atmospheric PECVD operates at atmospheric pressure and ambient temperature, allowing the use of a wide range of liquid precursors delivering high vapor coating rates onto flexible and rigid substrates. The process is currently being researched to deposit functionalities such as anti-fog, lubricity, corrosion resistance and electrical resistance.
