How to Use This Calculator
- Enter product dimensions (length, width, height in mm) and the number of cavities per card.
- Enter thermoform material thickness (mm) and card stock weight (g/m2).
- Read total blister pack dimensions, cavity layout, and material area (cm2).
- Review forming depth-to-width ratio — ratios above 1:1 may cause thinning or tearing.
- Use cavity dimensions and material area to quote tooling and material costs.
