An Optimum Mixture of Virgin Bagasse Pulp and Recycled Pulp (OCC) for Manufacturing Fluting Paper
BioResources, 2013 This study evaluated the properties of fluting paper made with a blend of unbleached bagasse soda pulp (340 mL CSF freeness) and OCC pulp (250 to 300 mL CSF freeness) of 0:100, 10:90, 30:70, 50:50, 70:30, and 90:10 ratios by weight, respectively. Some handsheets at 120 g/m2 basis weight were made.

The influence of consistency and fibre length on the yield stress of OCC pulp fibre suspensions
BioResources, 2017 The effect of fibre length on the yield stress of recycled old corrugated containers (OCC) pulp fibre suspensions was investigated. Two types of OCC pulps were divided into four fractions based on the fibre length with a Bauer-McNett classifier. The yield stress of each fraction was measured using the shear stress ramp method at pulp consistency ...
