Product Details

Paperboard, Scoring, Folding, Conversion, Bending

  1. This test is used to evaluate the bending quality of both coated and uncoated paperboard from 0.4 to 1.0 mm (0.016 to 0.040 in.) in thickness made on fourdrinier or multi-ply cylinder machines .
  2. The scoring and folding of a sample of paperboard is evaluated by scoring the board using different combinations of rule and die widths and die penetration depths and then folding the board along the score line.
  3. The bending quality of paperboard depends on both the elastic properties of the paperboard and the proper selection of the rule and die width and depth of die penetration used to score the board.
  4. The test results are used to assess the suitability of paperboard for conversion into folded cartons without score line rupture of the outer surface.
