Optimizing Calender Moisture Profiles for Board Bulk Retention
Retain board bulk and bending stiffness by applying surface moisture gradients to lower outer ply glass transition temperatures before soft nip compression.
How Paper Is Coated Calendered and Finished
Inline blade coating and soft-nip calendering establish surface uniformity, while targeted finishing passes balance visual embellishment against repulpability.
Calendering Moisture Profiles and Z-Direction Density Control in FBB Cores
Moisture-gradient calendering plasticizes outer chemical skins while keeping mechanical cores dry, maximizing FBB bending stiffness and yield.
Chemi-Thermomechanical Pulp Core Optimization for Low Grammage Boxboard Manufacturing
Optimizing CTMP core sulfonation and bulk yields lower grammage boxboard that maintains flexural rigidity while reducing landed carton cost.
Preserving Folding Boxboard Bending Stiffness during Weight Reduction
Preserving folding boxboard bending stiffness during weight reduction relies on maintaining mechanical core bulk while elevating outer ply elastic modulus.
Non-Contact Caliper Measurement Systems on High Speed Packaging Board Lines
Non-contact optical gauges eliminate mechanical board compression on high-speed lines, enabling tighter cross-machine caliper targets and reduced fiber mass.
