HONREL manufactures Custom PO Greenhouse Film with spectral control. Optimize UV blocking, light diffusion, and thermicity for precision crops. Factory Direct Wholesale.
If you grow crops like berries or flowers, you know that light is very important. Sunlight is like a recipe for your plants. The amount of red light and UV light changes how they grow. It also matters if the light scatters or hits the plants directly.
The right light makes your plants short and full of fruit. The wrong light makes them grow too tall and thin. Our special film helps you control this recipe. It scatters the light so it reaches every part of the plant. This film is long-lasting and perfect for shops.
To maximize yield quality, standard construction plastic is not enough. You need Custom PO (Polyolefin) Greenhouse Film engineered with Spectral Control. Unlike basic PE, our PO films allow us to use multi-layer extrusion to “tune” the plastic. We can block UV light to blind pests, diffuse PAR light to prevent leaf scorch, or block Near-Infrared (NIR) heat to cool the crop—all while maintaining over 90% light transmission.
At HONREL AGRICULTURE, we don’t just sell rolls of plastic; we act as your spectral engineers. In this guide, we will break down how light manipulation works, the clear advantages of PO over PE, and how to customize a recipe for your specific location.
In the past, the only goal of a greenhouse cover was to stop the rain and hold heat. Today, modern agriculture treats the film as a precise optical filter.
Most standard films degrade under UV. But with our advanced greenhouse po film, we can choose exactly which wavelengths to block or transmit.
Direct, sharp sunlight creates “hot spots” on top leaves and deep shadows below.
We often get asked: “Why should I pay more for Polyolefin (PO) instead of standard PE?”
The answer lies in the Coating Technology. Standard PE greenhouse film mixes additives into the plastic. Over time (12-18 months), these additives migrate to the surface and wash away, causing the film to lose its anti-drip and anti-fog properties.
HONREL PO Film is different. We use a 5-layer co-extrusion process where the anti-drip and spectral stabilizers are part of a permanent coating on the inner surface.
| Feature | Standard PE Film | HONREL Custom PO Film |
| Light Transmission | 88-90% (Degrades quickly) | 92-93% (Glass-like clarity) |
| Anti-Drip Lifespan | 1-1.5 Years | Lifetime of the film (3-5+ Years) |
| Tensile Strength | Moderate | High (Superior puncture resistance) |
| Spectral Accuracy | Basic | Precise (Custom Nanometer Cutoff) |
| Dust Resistance | Low (Static attracts dust) | High (Nano-coating sheds dust) |
Best Practice: For light deprivation setups where you need total darkness rather than light filtration, we recommend switching to our black and white panda film. It offers 100% opacity and heat reflection.
Do you need to keep heat in or keep heat out?
Even the best film will fail if it flaps in the wind. We recommend using proper locking profiles found in our Greenhouse accessories catalog. Ensure the film is installed with the correct side facing down (usually marked on the roll) to activate the anti-drip coating.
Spectral control doesn’t stop at the roof. To fully optimize your light environment, you must manage what happens under the canopy and on the walls.
To maximize the light you just filtered, cover your floor with white woven ground cover manufacturer material. This bounces the diffused light back up to the undersides of leaves and ripening fruit.
If you use a UV-blocking film to blind insects, don’t let them fly in through the window. Install high-mesh insect netting manufacturer screens on all intakes.
Custom spectral-control recipes require recalibrating our multi-layer extrusion lines. Because of this, the MOQ for fully customized PO greenhouse film is typically 3–5 tons.
For standard stock films, the minimum order quantity is much lower and depends on film thickness, width, and packaging requirements.
If you are unsure which option is best, our team can recommend a standard film or design a custom solution based on your crop and climate.
Agriculture is moving from simple protection to precision control. With HONRELAG Custom PO Film, you are not just buying a cover; you are investing in a tool that actively manages plant growth, reduces chemical use, and increases marketable yield.
Whether you need to block UV to stop pests or diffuse light for uniform growth, we have the manufacturing capability to blend the perfect recipe for your project.
