Calculated result

15.87 kg net film weight

15.87 kg net film · 15.87 kg gross with entered core

750 m² film area · 21.16 g/m² theoretical GSM

920 kg/m³ material density

15.87 kg gross roll weight

Show the working

1. Normalize length = 1,500 m, width = 0.5 m and thickness = 23 µm.
2. Film volume = length × width × thickness = 0.01725 m³.
3. Net film mass = volume × density = 0.01725 × 920 = 15.87 kg.
4. Theoretical GSM = thickness × density × 1000 = 21.16 g/m².

Material-only physics estimate. Actual rolls can differ because of resin blend, gauge tolerance, coatings, winding, labels and core/packaging mass. Use measured supplier data for purchasing acceptance.
