How well do you understand the relationship between your films and your corona treater? A treatment level of 2.0 watt density yields very different results on PET compared to Polypropylene. And, a nominal change in watt density can produce unexpected results. This paper looks at the relationship between various films and watt densities. Recognizing that each film has it own signature relationship with a corona treater will help converters control surface energy and improve adhesion. Source

The flexible packaging industry, despite the stillebbing recessionary downturn, continues to experience a technological revolution aimed at value-adding graphics, increasing consumer motivation, and delivering sustainable solutions for a host of challenges throughout the manufacturing and distribution chain. High performance package configurations and new printing technologies continue to drive packaging into existing as well as completely new markets. Statistically, the Freedonia Group forecasts revenues for the US commercial printing industry will reach $82 billion in 2011 and that US demand for printing inks will grow 1.8% annually to reach $4.8 billion by 2013. And although the global packaging industry is valued at a burgeoning $450 billion, the emerging markets of China and India for example convert only about 7% of all their packaging by aqueous-based printing processes. The market growth opportunities for flexible package printing are therefore vast. As new state-of-the-art flexible packaging technology is installed in these markets and with processing costs under pressure to enable these technologies to ramp-up in 2011, surface pre-treatment technologies must become a key enabler relative to higher processing speed, wider widths, and requirements on inks and coatings to transfer and adhere to substrates at these speeds and widths. This paper presents evidence of new flexible packaging print performance opportunities using a new, revolutionary atmospheric plasma treatment (APT) technology. Source

Low-pressure plasmas have been used for many years to surface treat polymer films, nonwovens and coated substrates. The complexity, slow speed and high cost of these contained plasma systems made them impractical for all but the most esoteric applications. This paper covers a new and improved system that allows plasmas to be sustained at atmospheric pressure in a way that permits the surface treatment of coated or uncoated textile products on a continuous webhandling system similar to a corona treating system. The Atmospheric Plasma Treatment (APT) process allows treatment using a broad range of reactive gases and has been successfully tested and implemented on various textile fabrics. Further, depending upon the dyne level required and type of textile material, line speeds in excess of 100mpm are practical and over 600mpm have been achieved. Specialty applications requiring stringent surface-morphology specifications, specific surface modification such as hydrophilicity, precise surface dyeing/coating or tightly controlled surface characteristics will find the APT system especially attractive and useful. A particular solution provided by the APT system, of significant importance to the textile industry and described in this paper, is enhanced wettability for dyeing and printing with water-borne formulations.

Conference Proceedings for the 81st Annual Convention of the Wire Association International | Year: 2011

Wire and cable jacketing materials are typically made from thermoplastics (PVC, ETFE, FEP, PP, TPE, PUR, etc), thermosets (CPE, CP, XLPE, EPDM, Si, etc) or fibrous coatings such as fiberglass or K-Fiber. All have low levels of polar functional groups on the surface and have poor wettability and adhesion properties, making it difficult to apply other functional layers such as inkjet inks, adhesives and coatings. Many experiments have been performed globally to investigate ways of improving adhesion to the materials used in wire and cable jacketing. Bonding connectors to wire ends is also critical, requiring cleaning and functionalizing to optimize dependable connections. This paper discusses current atmospheric surface activation systems, appropriate measurements of wettability and adhesion, over-treatment effects and surface analysis techniques relative to optimizing the adhesion of inkjet inks, coatings and adhesives to these polymer and fibrous surfaces. Atmospheric plasma cleaning of connectors is also discussed, along with recommendations for improved activation by substrate. Source

Automotive plastics with a low polarity, such as PE, PP, TPO, POM, PUR and PTFE typically require surface treatment when decoration is required. Metallic surfaces may also require cleaning to remove low molecular weight organic materials prior to decoration. Once the above-mentioned interior and exterior grades of substrate surfaces are cleaned and activated, printing, gluing and painting are possible without the use of adhesion-promoting primers. This paper describes the latest innovations in three-dimensional surface treating technology for plastics finishing which address the need to advance adhesion properties, increase product quality, and achieve environmental objectives within the automotive industry. These innovations include advanced thermal and non-thermal discharge treatment processes for raising the polarity of surfaces to be painted, bonded, decorated, laminated, printed, or to have tape applied.
