Wood & Paper Manufacturing worked example

Box Compression Margin with actual box compression strength of 63 value: a worked example

This worked example runs the box compression margin numbers for a tougher week than the baseline: actual box compression strength of 63 value instead of the typical 125 value. Estimate box compression margin for wood and paper manufacturing using production-ready inputs so teams can measure the gap between available and required amounts.

The inputs for this scenario

  • Actual box compression strength (BCT): 63 value (the input this scenario stresses; the baseline uses 125)
  • Required stacking strength for the load: 100 value (held at the documented default)
  • Reference required strength (baseline): 100 value (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Box compression margin amount gap = available box compression margin amount - required box compression margin amount.
  • Box compression margin works out to -37 % at these inputs, and this is the headline figure for the scenario.
  • Box compression margin amount gap works out to -37 value at these inputs.
  • Available box compression margin amount works out to 63 value at these inputs.
  • Required box compression margin amount works out to 100 value at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where actual box compression strength sits at 125 value and the headline result is 25 %, this scenario comes in 248% below the baseline at -37 %.
  • Use it when qualifying a new board grade, responding to a crush complaint, or right-sizing an over-built case to cut fiber cost. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Box compression margin: -37 % (headline result)
  • Box compression margin amount gap: -37 value
  • Available box compression margin amount: 63 value
  • Required box compression margin amount: 100 value
