What determines the price of a big bag: 8 factors
A big bag's price is set by eight parameters: size, number of loops, fabric density, spouts, polyethylene liner, safety factor, printing and batch size. Spouts add the most (+20–30%), followed by the liner and four loops (+15–25% each), while a batch of 1000+ pieces cuts the unit price by 15–30% compared with 50 pieces.
Size and load capacity
The larger the bag, the more fabric, thread and loop material it takes. A 500 kg bag (75×75×100 cm) needs ~3.6 m² of fabric for the walls and bottom, a 2000 kg one (100×100×165 cm) ~7.6 m² — more than twice as much material.
Number of loops: 2 or 4
A 4-loop big bag costs 15–25% more than a 2-loop one: more loop material, more complex sewing (4 attachment points instead of 2) and a higher load rating.
Fabric density (g/m²)
Standard density is 160–180 g/m², heavy-duty is 200–220 g/m²; the price difference is 10–15%. Denser fabric is needed for heavy abrasive materials (crushed stone, ore) and for multi-trip use.
Spouts: filling and discharge
A flat bottom and open top is the cheapest option. Every spout (filling on top, discharge at the bottom) adds to the price: a bag with both costs 20–30% more than the basic one.
Polyethylene liner
An inner PE liner adds 15–25% to the cost. Thickness (60–150 µm) and type matter: loose, gusseted or form-fit. Form-fit is the most expensive but follows the bag shape best.
Safety factor: 5:1 or 6:1
A big bag with SF 6:1 (multi-trip) costs 10–20% more than SF 5:1 (single-trip): 6:1 needs denser fabric, reinforced seams and loops. If you plan 2–3 cycles, 6:1 pays off.
Printing and branding
Logos are applied by flexo printing in 1–4 colors. One color is a minimal surcharge, four-color printing on all sides is more substantial. The minimum batch with printing is 1000 pcs.
Order volume
The wholesale price is 15–30% lower than for a small batch. The lowest unit price comes with batches of 1000+ pcs; at 50–100 pcs the price is higher because of fixed production setup costs.

| Spouts | No spouts | Top + bottom | +20–30% |
| Liner | No liner | Form-fit 100 µm | +15–25% |
| Safety Factor | 5:1 | 6:1 | +10–20% |
| Printing | No printing | 4 colors | +5–15% |
| Batch | 1000+ pcs | 50 pcs | +15–30% |
How to save money without losing quality
- ✔Define the real need: for loads up to 1000 kg without stacking, a 2-loop SF 5:1 bag is enough.
- ✔A liner is not always needed — dry materials in a closed warehouse can do without one.
- ✔Increase the batch — the difference between 50 and 1000 pcs is significant.
- ✔Spouts — only if your process really needs them.
- ✔Buy directly from the manufacturer — no intermediary or distributor markups.

Frequently Asked Questions
Why do big bags from different manufacturers cost differently?
The difference is usually in fabric density, loop quality, UV stabilization and ISO certification. A cheaper bag may use 120 g/m² fabric instead of 180 — invisible to the eye but critical for safety under load.
What is cheaper: single-trip 5:1 or multi-trip 6:1?
Single-trip is 10–20% cheaper per unit. But if you plan 2–3 cycles, multi-trip 6:1 is cheaper overall: one 6:1 bag replaces 2–3 bags rated 5:1.
Does color affect the price?
Standard white is the cheapest. Colored polypropylene (green, blue, beige) costs 5–10% more because of the pigment and is ordered in batches from 500 pcs.
