PULP, PAPER & PAPER BOARD TESTING

Paper and Paper Board Tests

  • Analyze paper and paper board physical and optical properties such as texture, grammage, brightness, thickness and density.
  • Examine the proximate chemical analysis for moisture, ash, extractives which include alcohol-cyclohexane, 1% NaOH, and hot/cold water and klason lignin.
  • Determine strength properties such as resistance to bending, puncture, tearing, and crushing force of paper and board.
  • Based on the following standards:
    • ISO 2470 (Measurement of diffuse blue reflectance factor)
    • ISO 2471 (Determination of opacity)
    • ISO 1974 (Determination of tearing resistance)
    • ISO 536 (Determination of grammage)
