The trials documented in this paper were run on a pilot coextrusion coating line at the Tampere University of Technology's Institute of Paper Converting in Finland. The study was conducted to test the ozonization system that was installed in our pilot line to treat the polymer melt in extrusion coating. The effect of the ozone, generated at the corona treater, on adhesion was studied. Ozone was first captured and transported to the nip with separate pipes. It was then led to an air knife near the air gap and blown against the polymer melt. The measured adhesion showed the usefulness of this technique. The following parameters were varied to determine the effectiveness of the ozone: substrate, line speed, coating weight, and melt temperature. Results indicated that thicker coating weights and higher melt temperatures improved adhesion values. The corona-generated ozone clearly improved adhesion compared to corona-treated or untreated samples.

With the advent of readily available nonpaper substrates (plastics and foils) in the mid-to-late 1950’s, the requirement for a reliable production speed surface treatment process became apparent. Several different technologies have been tried, but one, corona treatment, has become, by far, the primary surface treatment technology used across the Extrusion and Converting Industries. We will touch on these various technologies, technically describe the need for surface treatment and how it is measured, trace the development of corona treatment as the leading surface treatment method, and detail the current state-of-the-art in equipment, control parameters and applications.

The effect of time and surface contact on corona treated material can be measured and evaluated. Both components cause degradation of dyne level readings of wettability. However, the most significant cause, though it can be isolated, cannot be completely eliminated. A solution to the problem is possible but requires cooperation between material producers and converters.
