High-Performance Polyolefin Greenhouse Film for Modern Agriculture
Product Description:
PO Greenhouse Film, also known as Polyolefin Greenhouse Film, is a high-performance agricultural covering film designed for modern greenhouse cultivation. It is commonly manufactured using multi-layer co-extrusion technology, allowing different functional layers and additives to work together to provide excellent light transmission, UV resistance, mechanical strength, condensation control and thermal performance.
PO greenhouse film is suitable for vegetable greenhouses, fruit cultivation, flower production, nurseries, tunnels and commercial multi-span greenhouses.

| Elongation at Break | ≥ 600% |
| Shrinkage Rate | ≤ 5% |
| Temperature Resistance | -40°C to 80°C |
| Technology | Five-layer co-extrusion production process |
1. High Light Transmission
PO film is designed to provide high light transmission, helping more sunlight enter the greenhouse and supporting photosynthesis and crop growth.
Benefits for crops:
Better sunlight availability
Supports photosynthesis
Helps promote healthy plant growth
Suitable for vegetables, fruits and flowers
2. Excellent UV Resistance
PO greenhouse film can incorporate UV stabilizers to improve resistance to ultraviolet radiation and outdoor weathering.
This helps the film maintain its mechanical and optical performance during long-term greenhouse use. Actual service life depends on the film formulation, thickness, UV package, climate and installation conditions.
3. Anti-Drip Performance
Anti-Drip technology helps condensation water spread along the inner surface of the film instead of forming large droplets that fall directly onto crops.
This can help:
Reduce water droplets on leaves
Improve greenhouse humidity management
Maintain better light conditions
Create a more favorable growing environment
Anti-drip performance is particularly useful in humid greenhouse environments.
4. Anti-Fog Performance
Temperature differences between day and night can cause condensation and fogging inside a greenhouse.
PO film can be formulated with Anti-Fog properties to reduce condensation fog and help maintain better visibility and light conditions inside the greenhouse.
5. Thermal Insulation
PO greenhouse film can be customized with IR / thermal retention technology to help reduce heat loss and maintain a more stable greenhouse temperature.
This is particularly valuable for:
Winter cultivation
Early-season planting
Cold climates
High-value crops
Year-round greenhouse production
