Bag Weight Calculator
Industry-standard weight estimation for woven PP / HDPE bags.
Method:
Quick Presets
Bag Specifications
Step-by-step Calculation
1. Cutting length = 36 + 1 = 37"
2. 24 × 3 = 72.00
3. 72.00 ÷ 39.37 = 1.8288 g/inch
4. 1.8288 × 37 = 67.67 g fabric
5. 67.67 + 2 (thread) = 69.67 g per bag
Result
Per bag
69.67g
≈ 0.07 kg per bag
Cutting size24" × 37"
Equivalent GSM118.1 g/m²
Fabric weight67.67 g
Stitching thread+ 2 g
Total bags1,000
Total weight69.67 kg
Formula Reference
Trade Formula (Industry Standard)
Weight (g) = (Width" × Fabric gram × Cutting Length") ÷ 39.37- Cutting Length = Finished Length + Bottom Fold + Top Hem
- 39.37 inches = 1 meter (unit conversion)
- Used directly for tubular woven PP/HDPE
- "3 gram" fabric ≈ 118 GSM ; "2 gram" ≈ 79 GSM
Technical (GSM)
Weight (g) = 2 × W × L × (1 + seam%) × GSM ÷ 10000- Dimensions in cm, GSM in g/m²
- 2× for tubular (front + back panel)
- Useful for engineering specs / spec sheets
- Tolerance: ±3–5% in actual production
