PO Film vs PE Film: Which Greenhouse Film Should You Choose?

Q: What does PO film actually stand for?

PO stands for polyolefin. In the greenhouse industry, PO film refers to multi-layer co-extruded polyolefin films with a UV stabilizer package - the mainstream long-life covering for vegetable and berry greenhouses.

Q: Can I test both films before committing?

Yes. Free samples are available, and many buyers run a PO bay next to their existing PE for one season - comparing temperature, condensation and light inside their own tunnel. Lead time for production orders is typically 30+ days.

PO Film vs PE Film: Which Greenhouse Film Should You Choose?

PE and PO greenhouse films look almost identical on a roll — but they behave very differently over three seasons. This comparison walks through light transmission, lifespan, heat retention, anti-drip performance and the real cost per season, so you can decide with numbers instead of price tags.

PO vs PE — At a Glance

PE film is the budget workhorse: cheap, light, easy to install — but single-layer PE typically lasts 1–2 years under real UV load.
PO film (polyolefin) is co-extruded in 3 or 5 layers with a UV stabilizer package: up to 90% light transmission and a 3–5 year lifespan.
The deciding number is cost per season, not price per square meter — a film that lasts 4 seasons at a higher unit price usually wins.
PE still makes sense for short-cycle crops, seasonal tunnels and tight first-year budgets.
PO wins for multi-season vegetables, high-value crops, strong-UV regions and anywhere replacement labor is expensive.

What PE and PO Films Actually Are

🟡

PE film (polyethylene)

The most widely used greenhouse cover in the world. Single-layer or basic 3-layer construction, typically 150–200 μm for greenhouse use. Low upfront cost and easy availability — but UV resistance depends entirely on the additive package, and basic PE degrades in 1–2 years.

Budget1–2 years

🟢

PO film (polyolefin)

A multi-layer co-extruded polyolefin film. Each layer has a job: outer layers carry the UV stabilizer package, inner layers handle clarity and anti-drip. Result: up to 90% light transmission, service life of 3–5 years, stable performance from −40°C to +60°C.

Mainstream3–5 years

Where does EVA fit?

EVA film is the insulation specialist — best heat retention of the three, aimed at flowers, nurseries and cold-night regions. If your bottleneck is night temperature rather than lifespan, see our crop & climate guide for the full PE / PO / EVA decision.

Cost per Season: The Math That Decides

PE looks cheaper on the invoice. But covering a greenhouse is a recurring cost, and the honest comparison is total covering cost per season of production. The table below shows the pattern we see across export markets (illustrative figures — ask us for current pricing on your spec):

Cost item	PE film, replaced every year	PO film, replaced every 4 years
Film purchases per 4-year cycle	4× (every year)	1×
Installation labor per 4-year cycle	4× removal + refit	1×
Downtime during replacement	Days out of production, every year	Once in 4 years
Light quality in later seasons	Degrades within each season’s film life	Consistent, high transmission
Crop risk	Undersized film fails mid-cycle	Stabilized against embrittlement

Rule of thumb: if your tunnel produces for more than two seasons, price PO per season instead of per square meter. For most multi-season vegetable and berry operations, PO film’s per-season cost comes out at or below PE — with better light the whole way through.

When PE Is Still the Right Answer

First-year budget cap

If capital is the binding constraint, PE gets you growing now — plan the PO upgrade into year 2.

Short-cycle / seasonal crops

One season of production doesn’t need a 4-season film.

🍅

Multi-season vegetables

PO 3–5 yr

Tomato, pepper, cucumber — the balanced default for tunnels you keep.

🏜️

Strong-UV regions

PO high-UV

Desert and high-altitude sun eats basic PE in months; the stabilizer package decides life.

Expensive or scarce labor

Every avoided re-covering job saves labor you probably can’t easily hire.

How to Decide: A Simple Flow

1 · How long will the tunnel produce?

1 season → PE · 2+ seasons → keep going

2 · How strong is your UV?

Desert / high altitude → PO high-UV package

3 · What does the crop hate most?

Dripping water → PO anti-drip · cold nights → consider EVA

4 · Compare cost per season

Film + labor + downtime ÷ seasons of production

Common Mistakes to Avoid

⛔

Mistake 1

Comparing price per square meter instead of cost per season. A cheap film bought four times, installed four times, with three production interruptions is rarely the cheap option.

⛔

Mistake 2

Judging light transmission on day one. All films look clear when new. The difference shows in year 2 — yellowed PE can cost more yield than the film ever saved.

⛔

Mistake 3

Buying “thick PE” as a lifespan fix. Thickness is not UV protection. Without a proper stabilizer package, a thick film still embrittles on schedule — you pay for polymer, not for life.

Buying Checklist

What to ask before you order either film

Measured light transmission — request the lab value, not “high clarity” (our PO film: 90%).
Stabilizer package — which UV system, and guaranteed life at your region’s UV index.
Anti-drip durability — how many seasons the anti-drip effect lasts, not just whether it exists.
Structure — 3-layer or 5-layer co-extrusion, width (up to 16 m) and length per roll.
Proof — a free sample roll or a trial bay before committing the whole farm.
Terms — MOQ (1000 kg per roll spec), lead time (typically 30+ days) and export documentation.

Ordering tip: send us your crop, tunnel dimensions, climate zone and target lifespan. Our factory team will quote both a PE and a PO option with a per-season cost comparison, so you can see the trade-off on your own numbers. Free samples are available for trial bays.

Common Questions About PO vs PE Film

What does PO film actually stand for?

PO stands for polyolefin. In the greenhouse industry, “PO film” refers to multi-layer co-extruded polyolefin films with a UV stabilizer package — the mainstream long-life covering for vegetable and berry greenhouses.

Is PO film worth the extra cost over PE?

For tunnels producing more than two seasons, usually yes. PO film delivers up to 90% light transmission, a 3–5 year lifespan and long-lasting anti-drip performance, so its cost per season typically matches or beats PE once you include replacement film, labor and downtime.

How long does each film last in a strong-UV region?

Basic PE film typically lasts 1–2 years, and less in desert or high-altitude UV. PO film with a high-UV stabilizer package is rated for 3–5 years; we quote the guarantee against your local UV index.

Can PE film be UV-stabilized to last longer?

Yes — UV-stabilized PE extends life versus basic PE, but it remains a single-additive system. Multi-layer PO puts stabilizers, clarity and anti-drip in dedicated layers, which is why its transmission and anti-drip performance hold up longer, not just its tear strength.

Which film is better for humid climates?

Humid climates put condensation high on the problem list. PO film’s built-in anti-drip layer makes condensation run down the walls instead of dripping onto the crop, reducing disease pressure — a major advantage for fruiting vegetables and flowers.

What widths and thicknesses are available?

Greenhouse film is produced to order: widths up to 16 m, custom roll lengths, 3-layer or 5-layer co-extrusion. PE greenhouse film is typically 150–200 μm; PO film thickness is matched to your climate and lifespan target. MOQ is 1000 kg per specification.

Can I test both films before committing?

Yes. We supply free samples, and many buyers run a PO bay next to their existing PE for one season — comparing temperature, condensation and light inside their own tunnel. Lead time for production orders is typically 30+ days.
