The greenhouse film that works in a temperate tunnel can fail within one season in a desert. Light, humidity and temperature are different for every crop and every climate — and the film formula should be matched to both. This guide walks through the main crop and climate scenarios, then compares PE, PO and EVA films so you can order the right structure the first time.
Four seasons, moderate sun and cold winters. The film must balance UV stability with good heat retention for spring and autumn growing.
High humidity and strong sun year-round. Prioritize UV stabilization, anti-drip, and ventilation-friendly designs over insulation.
Extreme UV and heat. Film must resist rapid degradation — don’t chase maximum light transmission; chase stabilizer quality and longevity.
Big day-night temperature swings. Strong insulation and anti-drip matter more than peak light; thermal films hold night heat.
Salt air and wind load shorten film life and stress the structure. Specify tear-resistant film and reinforce the cover system.
Fruiting vegetables want high light transmission for yield and good heat retention at night. Anti-drip keeps humidity off the canopy.
Botrytis and spotting start with dripping water. Anti-drip film plus good light diffusion protects petals and improves grade-out.
Lettuce and herbs prefer diffused light to avoid tipburn and bolting. Light-diffusing films even out canopy temperature.
Young plants need stable night temperature and protection from cold drafts. Insulated films reduce heating cost in propagation.
Combining a greenhouse cover with mulch film controls fruit cleanliness and ripening pace — a proven high-value setup.
Vigorous growers that appreciate warmth; anti-drip matters when humidity climbs inside dense canopy.
| Property | PE 3-layer | PO 3-layer | EVA 3-layer |
|---|---|---|---|
| Light transmission | Good (standard) | High (up to ~90%) | High |
| Typical life | 1–2 seasons | 3–5 years | 3–5 years |
| Heat retention | Moderate | Good | Excellent |
| Anti-drip option | Optional | Common | Common |
| Best fit | Budget tunnels, short cycles | Mainstream vegetables & berries | Flowers, nursery, high-value crops |
Ordering tip: tell us your crop, climate zone and tunnel size. Our factory team recommends the structure (PE / PO / EVA), UV level and feature set, and supplies greenhouse film up to 16 m wide at factory-direct pricing.
How long does greenhouse film last?
Standard PE film typically lasts 1–2 seasons. PO and EVA films with a proper UV stabilizer package last 3–5 years in most climates; in extreme UV regions, the guarantee should be quoted against your local UV index.
Is PO film worth the extra cost over PE?
For a greenhouse you keep for more than two seasons, usually yes: PO gives higher light transmission, better heat retention and a 3–5 year life, so the per-season cost often ends up lower than replacing PE every year.
How do I choose film for a desert / high-UV region?
Prioritize the UV stabilizer package and guaranteed life over peak light transmission. A slightly lower-light film that survives 4 seasons is cheaper per season than a brighter film that embrittles in 12 months.
Why do flower greenhouses need anti-drip film?
Condensation dripping onto petals causes spotting and botrytis. Anti-drip film makes water run down the walls in a film, keeping the canopy dry and improving flower grade-out.
What does 3-layer co-extrusion mean?
Three layers are melted together in one pass, letting the manufacturer put the stabilizer where it protects and the thermal/anti-drip additive where it works — a stronger, more even film than a single-layer sheet. Five-layer co-extrusion adds even more control.
Can greenhouse film be made to my width and length?
Yes. Greenhouse film is produced to your width (up to 16 m), length and gusset spec. Send your tunnel dimensions and crop details for a tailored quote.
What is the difference between anti-drip and thermal film?
Anti-drip stops condensation from falling on the crop; thermal (or infrared) film reflects night heat back inside to hold temperature. Many PO and EVA films combine both features.
