Calculated result

1.75 yd tape per box

H-seal (3 strips) · 1.67 yd before allowance

175.44 yd planned for 100 boxes

3 whole yd-rolls · 4.56 yd projected remainder

12 entered-currency roll cost

Show the working

1. Center strip = 18 + 2 × 3 = 24 in.
2. Each cross strip = 12 + 2 × 3 = 18 in.
3. Base H-seal tape = center + 2 cross strips = 1.67 yd.
4. Allowance model = base ÷ (1 − 5%) = 1.75 yd/box.
5. Batch = 1.75 × 100 = 175.44 yd; rolls = ceil(batch ÷ 60) = 3.

Planning estimate, not a package-performance certification. Required tape pattern, width, grade, adhesion and strip count depend on carton, contents, environment, carrier and tape manufacturer guidance. Measure real consumption for procurement calibration.
