The BottleDyne™ Corona Surface Treatment System

Taking unique advantage of open air corona discharge, directed to the surface requiring treatment, 3DT’s self-contained BottleDyne pre-treating surface treatment system sets new standards for corona technology. It’s now possible to in-line corona treat virtually any extrusion or injection blow molded container. The surface treatment is done delicately, quickly and efficiently, without damage to the surface being treated or adverse effect on the molding, printing or labeling process.


The BottleDyne Surface Treatment System advantages:

  • Treatment of cylindrical, rounded oval, rectangular and square containers.
  • Line speeds up to 7,000 parts per hour.
  • Treating levels up to 70 mN/m (dyne/cm) depending on the application.
  • Compact inline and maintenance friendly designs with one easy to clean or change electrode assembly.
  • Open air corona discharge, directed to the surface requiring treatment, for high treating levels, even on polypropylene containers.
  • Easily installed into molding, printing and filling lines or used as a stand-alone work-station.
  • No open flame and no heat developments to contaminate the work environment or to increase insurance premiums.
  • Damage-free, consistent treatment for highly improved adhesion.
