Corona treating for blown and cast film extrusion operations
Film extruders use corona treaters to increase a film’s surface energy at the time of extrusion. This pretreatment process enables the film to be later converted by printers, coaters & laminators.
Surface Treating for Extrusion Coating
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.
