PO Greenhouse Film: The Ultimate Buyer’s Guide (2026)

PO greenhouse film — short for polyolefin greenhouse film — is a multi-layer co-extruded agricultural covering that delivers 90–92%+ light transmission, built-in anti-fog, and a 3–5 year service life. It is the premium alternative to traditional PE film for commercial growers, because the UV stabilisers and anti-fog agents are compounded inside the resin instead of surface-coated, so performance lasts the full life of the film. This guide explains what PO film is, how it compares to PE, why layer count matters, and how to choose the right grade for your climate and crop.

What Is PO Greenhouse Film?

PO (polyolefin) greenhouse film is made from a blend of polyethylene, EVA and other polyolefin resins, co-extruded into multiple functional layers. Unlike PE film, where anti-fog is applied as a surface coating that gradually washes off, PO film carries anti-fog, anti-drip, UV stabilisers, and thermal additives inside the resin itself. That single difference is why PO film keeps its performance for 3–5 years while economy PE film fades after one or two seasons.

Why Layer Count Matters: 3-Layer vs 5-Layer vs 7-Layer PO Film

The number of co-extruded layers decides how many functions the film can carry without compromise. In a 3-layer film, additives are mixed together; in a 5-layer or 7-layer film, each function lives in its own layer:

• 3-layer PO film — economy PO; UV + anti-fog in fewer dedicated layers.
• 5-layer PO film — the commercial standard; separates UV, thermal (IR), anti-fog, and structural layers for balanced long-life performance.
• 7-layer PO film — maximum customisation: anti-dust, light conversion, photoselective spectra, and barrier functions each in their own layer; used for high-value crops where optical precision pays.

InFunPlastic produces PO greenhouse film on advanced co-extrusion lines, with UV-stabilised 5-layer grades as the core commercial product and higher-layer custom builds on request.

How to Choose the Right PO Film: Thickness by Climate

What You Can Customise

• Thickness: 80–200 µ (0.08–0.20 mm)
• Width: 0.5–22 m, with welded side joints for large spans
• UV grade: 1-season to 5-year formulations
• Light diffusion: clear, medium (35–50%), high (60–75%)
• Add-on functions: anti-dust, light conversion, photoselective spectra
• Roll printing and private label for distributors

PO Greenhouse Film FAQ

What is PO greenhouse film?

PO (polyolefin) greenhouse film is a multi-layer co-extruded agricultural covering with UV stabilisers and anti-fog agents built into the resin, offering 90–92%+ light transmission and a 3–5 year service life.

PO film vs PE film: which is better?

For high-value crops and long cycles, PO film wins on light transmission, built-in anti-fog life, night insulation, and service life. PE film is the economy choice for budget seasonal tunnels.

How long does PO greenhouse film last?

Standard UV-stabilised PO film lasts 3–5 years; high-UV grades for tropical zones are formulated at the top of that range.

What thickness PO film do I need?

Tropical and high-UV zones: 150–200 µ; temperate: 100–150 µ; cold or storm-prone regions: 180–200 µ heavy-duty.

Is 5-layer or 7-layer PO film worth it?

More layers let each function live in its own layer, so UV, anti-fog, thermal, and optical performance hold up better over the film’s life — worth it for high-value crops and harsh climates.

Can PO film be customised?

Yes. Thickness (80–200 µ), width (0.5–22 m), UV grade, diffusion level, and roll printing are all customisable.
