Commercial PO film greenhouse

Zheyang utilizes commercial-grade PO (polyolefin) film, manufactured using advanced multi-layer extrusion technology and designed specifically for commercial horticulture:

• Anti-fog performance: Compared to standard films, PO films utilize nano-coating technology that prevents water vapor from forming individual droplets on the surface. Instead, the moisture coalesces into a continuous, ultra-thin water film, which then flows into collection gutters around the perimeter of the greenhouse. This anti-drip property helps reduce the need for chemical fungicides and promotes healthy leaf growth.
• Consistently high light transmission: Within the photosynthetically active radiation (PAR) spectrum, light transmission can reach 92%—comparable to that of single-layer horticultural glass. Utilizing micro-prism diffusion technology, the material scatters intense direct sunlight, preventing heat-induced scorching of the crop canopy while allowing light to penetrate deeper into the lower canopy, thereby promoting uniform plant growth.
• High tensile toughness: With puncture and tear resistance three times greater than that of standard polyethylene film, it can withstand tearing caused by strong winds, hail, or structural deformation during use—a characteristic that directly extends the film's service life.

 

An integrated structure makes film greenhouses more reliable to use. 

Key points for the maintenance and upkeep of multi-span greenhouses:

Forcommercial PO film greenhouses  over long periods, the surface will inevitably accumulate dust, pollen, and soot. To ensure that light transmission remains above 90% throughout each growing season, the surface must be cleaned. In arid, barren, or dusty agricultural regions, the exterior roof should be washed twice a year using a low-pressure spray boom or a soft-bristled agricultural brush. Use a mild, pH-neutral, biodegradable soap; avoid abrasive scrubbing sponges or harsh, highly acidic or alkaline industrial cleaning agents.

For multi-span greenhouses equipped with double-layer, air-inflated PO film, maintain a dynamic pressure differential between 0.20 and 0.45 inches of water column (in. w.c.) by adjusting the dampers at the blower air intakes. Additionally, inspect the intake screens of the centrifugal blowers monthly to check for the accumulation of dust, leaves, and insects. Each autumn, clear all galvanized rainwater gutters of dead leaves, crop residues, and other debris.

To have a commercial PO film greenhouse customized by Zheyang, you need to provide four key pieces of information: 

• Project location and meteorological loads: maximum instantaneous wind speed, maximum snow load, snow depth, and minimum winter and maximum summer temperatures;
• Land dimensions and planning specifications: total area and plot aspect ratio, preferred span and bay width, and eave height;
• Crops and Cultivation Systems: Types of crops; whether the system needs to support the tension from high-wire trellising; and the specific cultivation method—such as soil-based cultivation, substrate cultivation (using coir or rockwool slabs), hydroponic piping, or mobile benches;
• Specific configuration for PO film: Selection of either a single-layer PO film or a double-layer inflatable PO film, along with choices regarding thickness and optical properties.
