Specialty Films, Membranes & Barrier Materials worked example

Lamination Yield at 68% target lamination yield rate: a worked example in specialty films, membranes & barrier materials

Here is what the math looks like when conditions slip. We hold every other input steady and drop target lamination yield rate to 68%, then walk the calculation through step by step. Estimate lamination yield for specialty films, membranes and barrier materials using production-ready inputs so teams can track KPI performance and decide whether corrective action is needed.

The inputs for this scenario

  • Rejected laminate rolls (delamination, bubbles, tunneling): 8 count (held at the documented default)
  • Total laminate rolls inspected: 250 count (held at the documented default)
  • Target lamination yield rate: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

  • The calculation starts from the formula this tool documents: Lamination yield rate = lamination yield count ÷ total lamination yield population × 100.
  • Lamination yield rate works out to 3.2 % at these inputs, and this is the headline figure for the scenario.
  • Lamination yield gap to target works out to 64.8 points at these inputs.
  • Lamination yield count works out to 8 count at these inputs.
  • Total lamination yield population works out to 250 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target lamination yield rate sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to target lamination yield rate, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. The tool divides the first field by the total, so if you enter defects rather than good rolls the headline rate reflects the defect share — read the result in the context of what you entered.
