FiberLean MFC Case Study for Offset Paper

MFC Grinder Case Study: Offset Paper Mill

Filler increase and softwood reduction for cost savings

Background

  • Offset paper grade: 70 g/m²
  • Base filler level: 26% (PCC)
  • Blend of hardwood and softwood pulp
  • MFC produced using G250 grinder with eucalyptus pulp

Trial Objectives

  • Add 1.25% MFC
  • Increase filler content
  • Reduce or eliminate softwood usage
  • Maintain paper properties and machine performance
  • Demonstrate cost savings

Trial Results

The trial successfully replaced fibre with filler while improving energy efficiency.

  • Ash content increased from 26% to 30%
  • Softwood fibre eliminated entirely
  • Reduced energy consumption
