Plastic Film Yield Calculator
Film yield in square metres per kg and square inches per pound from thickness and density.
Inputs
µm
g/cm³
Results
- Yield
- 55.25 m²/kg
- Yield
- 38,844 in²/lb
- Yield
- 269.7 ft²/lb
Formula
Yield (m²/kg) = 1000 ÷ (Thickness µm × Density)
in²/lb = m²/kg × 703.07
Assumptions & limits
- Theoretical yield of the base film; coatings and metallisation reduce it.
Worked example
1000 ÷ (20 × 0.905) = 55.25 m²/kg ≈ 38,844 in²/lb.
