Corona Applications

  • Coating Adhesion for Films with Corona, Flame & Plasma

    Successfully applying a high quality, continuous web coating requires advanced and versatile technologies which can effectively meet the varied needs for films. Surface treatment plays an important role in this process. The properties of the substrate are therefore absolutely critical to ensure good coating quality and product performance.

  • Converting Film With Corona, Plasma & Flame Surface Treatment

    Flexible packaging converters and label printers know that almost all engineered films have nonporus surfaces with inherently low surface energy. These films are surface treated at the time of extrusion, but also require in-line treatment at the time of conversion.

  • Corona Treatment For Extruded Film (Cast & Blown Film)

    Most cast and blown film extruding applications are best served with a covered roll surface treater. Enercon offers two types of covered roll systems for extruding applications.

  • Embossed film corona treating design minimizes pinhole potential

    Embossed films have peaks and valleys that create a special set of circumstances when it comes to interacting with corona. To minimize the chance of pinholing Enercon has developed a special ceramic electrode treater station design that minimizes filamentary discharges and also expertly manages the films’ exposure to watt density per square inch without sacrificing treatment levels.

  • Improve Ink Printing Adhesion with Surface Treating

    The task of optimizing printing adhesion can be difficult, primarily because of the many process variables which require control. There are six major printing/decorating processes, each distinguished by the method in which ink and an image are transferred to a substrate, and by the method by which the ink and image are conveyed for adhesion to a substrate. Almost all surfaces require preparation to establish minimum adhesion requirements. This step is known as pretreatment and post-treatment, and influenced by the base material surface receptivity of the ink layer.

  • Improve Lamination Adhesion with Surface Treating

    For many industrial applications, the use of a single ply of a material does not provide all of the critical properties required for the optimal performance of a product. In these cases, a composite of two or more layers of material can provide this required performance. A common method of creating such a composite is to laminate various materials to each other with an adhesive. Surface treating solutions such as corona treaters, atmospheric plasma systems and flame treaters are often used to improve lamination adhesion.

  • Metallized Film Adhesion: Processing & Converting with Surface Treatment

    Metallized film presents adhesion challenges to both film suppliers and converters. Today, new developments in surface treatment are creating competitive advantages by extending surface energy stability on metallized film.

  • Optimal blown film line layout for surface treatment

    When it comes to surface treatment on a blown film line there are a number of different philosophies employed. Factors including budget, available space, and specific application criteria all contribute to your ultimate decision.

  • Solvent Printing Ink Adhesion & Corona Treating

    The use of corona treating to improve adhesion on water based ink formulations is widely accepted as a best practice. However printers who use solvent inks may not realize that there is much to be gained from using a corona treater for solvent printing applications.

    Foams can be difficult to surface treat for adherence to other materials. Manufacturers use a variety of thermoplastic and thermoset resins, resulting in foams either having a high resident surface energy or low surface energy. Foams manufactured of low surface tension polyolefins require surface treatment when applying adhesives foams, in order for it to penetrate into the foam structure.
