The polypropylene woven sack is the most widely used packaging for dry bulk products. The price per piece looks small, but at millions of sacks a year every 5 g of fabric is tonnes of polypropylene. Here is where you can save — and where you can't.
Fabric weight by product
| Product | Fabric weight | Why |
|---|---|---|
| Flour, cereals | 60–70 g/m² | Light product, does not cut the fabric |
| Sugar, salt | 70–80 g/m² | Heavier; crystals abrade the fabric |
| Mineral fertilizers | 80–90 g/m² + lamination | Hygroscopic, often stored outdoors |
| Cement, dry mixes | 90 g/m² + lamination | Dust, moisture |
Lamination: needed or not
Lamination is a thin PP film on the fabric. It protects from moisture and dust but reduces breathability. For flour and cereals lamination is usually not needed (the product must breathe); for sugar, salt and fertilizers it is needed.
Sizes
The standard for 50 kg is 55×105 cm (flour, sugar) and 50×95 cm (salt, fertilizers with high bulk density). We produce widths from 45 to 120 cm — to suit your bagging line.
Printing
Flexo printing up to 4 colours. One-side print in 1–2 colours hardly affects the price; full-colour two-side print adds 8–12 %.
What the price is made of
- Sack weight (fabric weight × area) — 60–70 % of the cost.
- Lamination — +5–8 %.
- Printing — 0–12 %.
- Order size — from one truck (about 250,000–300,000 sacks of 50 kg) the price is 5–7 % lower than for small lots.
- Logistics — a truck from Turkmenistan to the Volga region and the Urals takes 5–7 days; within the CIS there is no import duty (ST-1).
Why the "cheapest" costs more
A sack made of recycled PP is 10–15 % cheaper but tears when dropped from a pallet and in frost. One torn lot at the buyer's warehouse costs more than a year of savings.
