【 摘 要 】

Coreboards are produced entirely from corrugated cardboard wastes and 165 to 450 g/m2 depending on the area of use and used as coil cores (tissue papers, bobbins, etc.). Calendering processes at different temperature, pressure and time were applied to coreboards surfaces in order to improve surface properties. The calendering process was applied to coreboards with 165, 275 and 400 g/m2 at 110, 130, 150 and 170 ºC temperatures for 3 and 5 seconds and under 10, 15, 20 and 25 bar pressure. Then, the surface roughness, Scott bond and air permeability properties of the coreboards were determined and the effects of calendering conditions on these properties were also examined. As a result of the study, it has been determined that applying the calendering process to the coreboard has a positive effect on the surface properties such as roughness, Scott bond and air permeability, and it is also thought that the calendering process will also improve theprint quality to be applied to coreboards.
