Paperboard dispersion-coated trays could be manufactured; how- ever, moisture content was reduced to 4.5 – 5.0% to prevent blanks from sticking to the equipment. Although this is an atypical procedure to prepare the materials for processing, it strongly affected coating blocking behaviour. Still, tray forming speed damaged coat integrity. Lower formation speed and higher temperature proved to qualita- tively reduce coat cracking, though fine-tuning is required to achieve a flawless converted coated paperboard tray. Overall, dispersion- coated substrates showed good machinability. The present study provided further insights into the relationship between coating properties and their influence on process parame- ters, posing an additional basis for future research.
