PO Greenhouse Film: A Smarter Covering Choice for High-Sunlight Greenhouses
Greenhouse covering materials directly affect the light transmission and temperature retention inside solar and plastic greenhouses, making them critical for stable vegetable and fruit production. Among today’s advanced options, PO (Polyolefin) greenhouse film has become a popular upgrade thanks to its high strength, high light transmittance, excellent aging resistance, and slow functional attenuation.

PO greenhouse film is produced using a refined polyolefin formulation—typically combining PE (polyethylene), EVA, and other polyolefin materials with functional additive systems through advanced manufacturing technology. Compared with conventional films, PO film delivers more stable performance over long-term use and is widely adopted in Japan and other markets.
Key Advantages of PO Greenhouse Film
1) Higher Light Transmittance
PO film provides excellent clarity and higher light transmission, improving photosynthesis and crop uniformity—especially important during winter or low-light seasons.
2) Better Heat Retention & Temperature Stability
Higher daytime transmittance helps the greenhouse capture more solar energy, often resulting in a warmer internal environment and better crop growth consistency.
3) Strong Mechanical Performance
PO film is known for high tensile strength and tear resistance, making installation easier and reducing damage risks during strong wind or tensioning.
4) Long Service Life with Slow Functional Attenuation
Compared with many standard films, PO film has a lower rate of performance decline, supporting multi-season use with more stable results.
5) Cleaner Recycling & Easier Disposal
Used PO film is generally easier to handle and can be recycled as a renewable resource. It also avoids the harmful gas concerns associated with some traditional materials during disposal.
Real-World Performance (Common Observations)
Field observations and greenhouse monitoring often show that PO greenhouse film can deliver:
Higher light transmittance than PE film, improving internal light conditions
Slightly higher average greenhouse temperature, supporting better winter performance
Reduced condensation on the film surface (when combined with effective anti-fog/anti-drip solutions), helping maintain clearer light conditions and lowering drip risk
