Results
- Film per pallet
- 94 g
- Roll length used
- 12 m
- Applied (stretched) length
- 36 m
- Revolutions
- 9 wraps
Formula
Wraps = ⌈H ÷ (film width × (1 − overlap))⌉ + extra
Applied length = wraps × pallet perimeter
Roll length = applied ÷ (1 + pre-stretch)
Weight = roll length × film width × µm × density
Assumptions & limits
- Film necking is ignored; real consumption is usually 5–15% lower in weight.
- Pallet corners are treated as square.
Worked example
9 wraps × 4 m = 36 m applied ÷ 3 = 12 m of roll ≈ 94 g.
