A greenhouse film is an engineered sheet — not a tube of plastic. Material, thickness, lifespan and total cost, in a practical field guide from a manufacturer co-extruding agricultural film since 1994.
Both are polyolefins. The difference is in clarity, service life and price — not in whether they “work”.
budget matters and you replace film every 3–4 seasons anyway.
light quality and a longer service life beat the upfront premium — flowers, nurseries, high tunnels.
5-layer co-extruded PE — the best price/life balance for most commercial growers.
Microns (µm) decide strength against wind, hail and tension. Pick your structure to see the spec.
The most common commercial spec. Balances light, strength and cost for seasonal production in moderate climates.
The base resin is half the story. These packages are what separate a film that lasts from one that chalks in a season.
Set real service life in direct sun. Weak UV package = early embrittlement.
Condensation runs down the wall instead of dropping onto crops and burning them.
Keeps clarity in high humidity so light actually reaches the plants.
Spreads light evenly, cuts leaf scorch and reaches lower canopy.
Retains heat at night — valuable in temperate and cold seasons.
Reduces static buildup so the cover stays clean and transmits more light.
A greenhouse film is an engineered product. These are typical values from a production lot — always ask for a lot-specific Certificate of Analysis.
| Thickness | 150 µm ±5% |
| Light transmission | 90% |
| Haze | ≤ 18% |
| Tensile strength (MD / TD) | 22 / 20 N/mm² |
| Elongation at break | ≥ 450% |
| UV warranty | 4 years |
| Width (as extruded) | 4 – 20 m |
Values measured per EN 17033 / ISO 4892. Your target spec may differ — tell us your crop and climate and we’ll tune the formula and send a lot-specific COA.
Cheap film per m² is often the most expensive film you can buy. Compare what really compounds over a season.
Same crop, different continent — different spec. Get the climate fit right before you order.
High UV, heavy humidity. Anti-drip is non-negotiable; go thicker to survive storms.
Four seasons, cooler nights. IR thermal pays for itself in heating savings.
Intense sun and dust. Max UV loading and anti-dust keep light transmission up.
PO wins on clarity and lifespan (4–7 years) but costs more. PE (3–5 years) is the value default. Choose PO for high-value crops and long seasons; PE for standard seasonal production.
120 µm for low tunnels, 150 µm for standard temperate greenhouses, 180 µm for large/commercial structures in wind, and 200 µm for harsh sun or storm-prone regions such as East Africa.
A well-stabilized PE film lasts 3–5 years; PO lasts 4–7. Life depends on the UV package and climate — always ask for the UV rating, not just the micron number.
Without it, condensation forms drops that fall on plants and act as lenses that scorch leaves. Anti-drip makes water sheet down the wall, protecting crops and clarity.
Yes. Widths from 4–20 m, custom micron, and tailored additive packages (UV / anti-drip / IR) are available with a 500 kg minimum — factory-direct from Infunplastic.
“Since switching to Infunplastic’s 5-layer PE, we’ve had no mid-season tears, and the light inside is noticeably better than the film we ran before.”
