Surface Treating for Extrusion Coating
Increase surface energy for printing
Extrusion coating processes benefit from surface treating in many areas. Polymer films are often corona treated at the primary and secondary unwinds prior to the extrusion coating process.
Flame treatment is used with high speed paperboard applications. Corona treating is also used as a post treater to enable additional converting of the coated film.
Many extrusion coating operations are finding significant benefits in introducing ozone at the nip of the film and extrudate. Ozone treatment on extrusion coating lines can improve bonding adhesion, enable lower extrudate temperatures, and promote higher line speeds.
