Corona Treaters for Blown Film Extruders

Professional Surface Treatment Systems for Plastic Film Production
The ELES Corona Treater Series is designed to improve the surface energy of plastic films produced by blown film extrusion lines. By increasing the dyne level of the film surface, the system ensures excellent adhesion for printing, lamination, coating, metallizing and converting applications.

Suitable for LDPE, LLDPE, HDPE, PP, OPP, CPP and many other plastic films, ELES Corona Treaters deliver stable, reliable and energy-efficient performance for continuous industrial production.
