The effects of Condebelt press drying on the densification of recycled sheets made from KOCC , AOCC UKP and BKP were examined using CLSM (Confocal Laser Scanning Microscope) and thermal image analysis techniques. It was shown that significant improvement in sheet density, compression strength, tensile strength, surface smoothness was obtained by Condebelt drying. Densification effect by press drying was most prominent for recycled KOCC sheets. And this beneficial effect of Condebelt drying of increasing sheet density and strength was shown to provide opportunities of reducing the utilization ratio of AOCC for cost saving.
