Calculated result

4.6 ft roll length per item

0.849 m² planned bubble-wrap area per item

114.2 ft total roll length for 25 items

1 roll required · 38.3 items per roll

1. Rectangular item surface area = 2 × (77,419 + 61,935 + 51,613) = 381,935 mm².
2. Base wrap area = 381,935 × 2 layers = 763,869 mm².
3. Planned area with 10% cutting/overlap allowance = 763,869 ÷ (1 − 10%) = 848,744 mm².
4. Equivalent roll length = 848,744 mm² ÷ 609.6 mm roll width = 4.6 ft per item.
5. Batch roll length = 4.6 × 25 = 114.2 ft.
6. Rolls = ceil(114.2 ft ÷ 175 ft) = 1.

Material-planning baseline, not a protective-packaging certification or cut-layout optimizer. Rectangular surface area is converted to equivalent roll length; folds, seams, corners, irregular shapes, bubble compression and real cut layouts can use more material. Use measured-use variance to calibrate future batches when you have a representative pack-out.
