The Industry Trends Lighter Packaging Papers

• Smaller boxes require a basis weight reduction
• Lighter packages need better strength utilization
• Trends in supermarket displays demand printed
  large scale packaging
• Lower cost manufacturing

the MultiForm HC HR combination acheive this
balanced dewatering . - Our MultiForm HR have
achevied a life of 86days, the longest so far,
Our HCW also showed very good life potential

Results / Benefits

• Customer required improved dewatering without
  negatively affecting retention and other sheet
  qualities.
• MultiForm HCW was supplied and resulted in a
  formation improvement on 120 and 150gsm
• The RCT values remained consistent
• The SCT values improved slightly at the 120
  150gsm grades.
• Improved retention 120gsm, flow rate of
  retention aid reduced from 550 to 330l/hr, a
  significant saving !
