1. High Light Transmission
Higher light availability helps crops receive sufficient sunlight for photosynthesis, healthy growth and improved crop quality. Commercial PO films are commonly designed around high-transmission performance, with some products achieving around 90% or more depending on formulation and grade.
2. Excellent UV Resistance
PO greenhouse film can be formulated with UV stabilizers to improve resistance to ultraviolet radiation and slow down photo-aging.
This helps reduce premature yellowing, cracking and embrittlement, supporting stable outdoor performance over the intended service period. Film life depends on UV formulation, climate, thickness, installation and other conditions.
3. Excellent Anti-Drip Performance
With anti-drip technology, condensation is encouraged to form a water film and flow down the surface rather than forming large droplets that fall onto crops.
4. Anti-Fog Performance
Anti-fog technology helps reduce fogging and condensation on the inner surface of the greenhouse film.
5. Better Thermal Insulation
PO greenhouse film can be formulated with IR heat-retention additives to reduce heat loss and help maintain a more stable temperature inside the greenhouse, particularly during colder nights.
6. High Mechanical Strength
PO greenhouse film can provide good tensile strength, tear resistance and puncture resistance, making it suitable for greenhouse structures exposed to wind and other outdoor stresses.
7. Long Service Life
High-quality PO greenhouse films are designed for long-term outdoor agricultural applications. Their actual service life depends on the UV package, film thickness, climate, greenhouse structure, installation method and local environmental conditions.
