A commercial tomato grower outside Tashkent replaced single-season PE with UV-stabilized PO greenhouse film — and stopped rebuilding his covering every spring. Continental winters, hot dry summers and a covering expected to hold 3–5 years with anti-drip through the cold season: this is what that change looked like on his numbers.
Tashkent-region growers operate in a climate with two expensive extremes: winters cold enough for sustained condensation inside the tunnel, and summers with UV strong enough to embrittle basic polyethylene within a single season. For growers running seasonal PE, the covering itself becomes a yearly project — purchase, delivery, two days of re-covering labor per house, and disposal of the torn film — before a single tomato is sold.
The grower’s own accounting made the pattern obvious: across three seasons, the combined cost of replacement film plus installation labor exceeded what a multi-year covering would have cost upfront. And the winter drip problem was costing yield in a subtler way — water dripping from the ceiling onto flower clusters raised disease pressure exactly when prices were highest.
In autumn 2025 we supplied PO greenhouse film for the first block of houses. PO film is a multi-layer co-extruded polyolefin: the outer layers carry the UV stabilizer package, the inner layer carries the anti-drip effect, and the structure holds up to 90% light transmission through a 3–5 year service life. Three specifics mattered for this site:
Central Asian UV at summer highs, plus reflective winter light off snow, is harder on film than maritime Europe. The stabilizer loading was matched to the region’s UV index for a 3–5 year rating.
The anti-drip effect is built into the inner layer: condensation sheets down the sides instead of dripping onto flowers and fruit — the difference between harvested and lost winter sets.
Film was produced to each span’s arc plus channel allowance, so installation ran without field seams — fewer stress points, faster fitting, no offcut waste.
| Factor | Seasonal PE (before) | PO film (after) |
|---|---|---|
| Covering replacements | Every season | Planned every 3–5 years |
| Winter condensation on crop | Dripped onto flowers and fruit | Sheets to the gutter — drip eliminated |
| Light transmission in winter | Degrades through the season | Held at ~90% (rated up to 90%) |
| Re-covering labor | Every spring, every house | Once per multi-year cycle |
| Cost per season of production | Film + labor, annually | Lower spread over the film’s life |
The remaining houses are being converted to PO as their PE covers reach end of season, and the grower has moved to ordering against a multi-year plan instead of an annual emergency. For buyers planning a similar switch: MOQ is 1,000 kg per specification, production lead time is typically 30+ days, and free samples are available for a side-by-side trial against your current film before you commit a whole site.
Is PO film suitable for continental climates with cold winters?
Yes — PO film performs across a −40°C to +60°C working range, and the anti-drip inner layer is most valuable in winter when the temperature gap between inside and outside drives heavy condensation.
How does the anti-drip effect work?
The inner layer changes surface tension so condensation forms as a continuous water film that flows to the gutter instead of forming droplets that drip onto the crop.
What did the switch from PE to PO actually save?
The visible savings are the annual replacement film and installation labor; the larger gain is winter yield protected from drip-borne disease during the highest-price weeks.
Can film be produced to my greenhouse’s exact width?
Yes — we produce to the arc of your span plus anchoring allowance, single-piece up to 12 m and factory-seamed beyond that. Send span, length and anchoring method for a size check.
What is the lifespan in a high-UV region?
With the stabilizer package matched to your region’s UV index, PO film is rated for 3–5 years. We quote the rating against your location’s conditions.
Can we trial the film before ordering a full site?
Yes — free samples are available, and a one-house trial through one winter is the standard way buyers validate PO film before converting the whole farm. MOQ for production orders is 1,000 kg per specification; lead time is typically 30+ days.
