Thermal Insulation Greenhouse Film Diffused 200 MICRON

Thermal insulation greenhouse film (also known as IR Thermal Film ) refers to agricultural coverage film manufactured by adding infrared barrier additives (IR Additives) or utilizing high-thermal-retention resins (such as EVA, Ethylene-Vinyl Acetate copolymer) into the base polymer.

While standard polyethylene (PE) film offers good daytime light transmission, it has extremely low long-wave infrared barrier capabilities (only 20%–30%). At night, thermal radiation emitted from the soil and crops inside the greenhouse escapes freely through standard film. Thermal film functions by blocking and reflecting this long-wave infrared radiation back into the greenhouse, effectively locking in heat.
Core Working Mechanism

Daytime Heat Accumulation: High transmittance of solar short-wave radiation (visible light and Photosynthetically Active Radiation, PAR) allows air and soil temperatures inside the greenhouse to rise rapidly.

Nighttime Heat Retention: High obstruction of long-wave infrared radiation (7,000–14,000 nm wavelength band) emitted by the soil, plants, and equipment suppresses radiation heat loss and slows nighttime cooling.

Product Detail

Thermal Insulation Greenhouse Film Diffused (200 Micron) is a premium 5-layer co-extruded greenhouse cover engineered for commercial operations that require both night-time thermal retention and deep canopy light diffusion. Formulated with Far-Infrared (FIR) mineral additives alongside micro-scattering agents, this heavy-gauge 200μm (8 mil) cover prevents severe night-time temperature drops while eliminating harsh direct solar glare during peak sun hours. As a specialized dual-benefit cover in our Thermal Insulation Greenhouse Film line, it reduces heating costs, protects sensitive crops from solar scorching, and fosters uniform canopy growth across our commercial greenhouse films collection.

Targeted Performance Benefits

  • Far-Infrared (FIR) Heat Retention: Mineral thermal additives trap long-wave infrared radiation re-radiated by soil and foliage at night, keeping greenhouse interiors 2°C to 5°C warmer than non-thermal films.

  • Deep-Canopy PAR Light Diffusion: Scatters direct sunlight into multi-directional ambient light, driving photosynthetically active radiation deep into lower leaf layers while preventing top-canopy leaf scorch and hot spots.

  • 15%–25% Heating Fuel Reduction: Minimizes night-time thermal loss, significantly reducing winter electricity and heating fuel consumption in climate-controlled structures.

  • Anti-Condensation & Anti-Fog Coating: Advanced internal coating lowers water droplet surface tension, creating a smooth runoff layer that prevents dripping on delicate crops and reduces Botrytis risk.

  • 8 Mil Heavy-Duty Durability: 200μm co-extruded polyethylene provides high tensile strain, exceptional tear resistance, and high load capacity against wind, heavy rain, and snow.

200 Micron Diffused Thermal Greenhouse Film FAQ

What is the advantage of a diffused thermal film over a clear thermal film?

Diffused thermal film scatters direct sunlight into multi-directional light, which penetrates deeper into dense crop foliage, reduces leaf-surface overheating, and eliminates shadows without sacrificing total PAR energy.

How does 200-micron diffused thermal film save energy?

It features mineral additives that absorb and reflect long-wave infrared (FIR) heat back into the structure at night, reducing heating fuel and electricity consumption by 15%–25%.

Does the anti-drip property last as long as the film?

The internal anti-fog additives are co-extruded into the inner film layer to provide long-lasting condensation control, preventing heavy dripping that causes fungal diseases like Botrytis.
