Goals

Learning outcomes :

  • To understand and know the calendering process (based on the thermophysical properties of lignocellulosic materials), in particular the main parameters of the thermoforming process
  • To state what an industrial application is, and what calendered papers are (comparison Europe/North America) and the different types of calender (smooth, supercalender, soft calender), the different calendering processes, the main calendering parameters, the mechanics of calendering, the heat of calendering, the effect of calendering on the structure of coated papers and the effect of calendering on thickness variations
