Light Blocking Agriculture Greenhouse Film Waterproof Greenhouse Blackout Plastic

Light Blocking Greenhouse Film Manufacturer For Agriculture

Product description:

Black and white greenhouse film is a functional agricultural film produced using a multi-layer co-extrusion process. One side is white, and the other is black. It is primarily made of PE (polyethylene) material, with added UV stabilizers, antioxidants, and other functional additives.

Unlike ordinary transparent greenhouse film, black and white greenhouse film uses a special color design to regulate light and temperature:

White side facing out: reflects sunlight, reducing the temperature inside the greenhouse.

Black side facing in: absorbs and blocks light, preventing stray light interference and improving shading effect.

Technical Parameter

Advantages:

1. Warm in winter and cool in summer, with outstanding temperature control.

In summer, the white side reflects heat, lowering the temperature inside the greenhouse by 5-10℃, preventing crops and livestock from being scorched by high temperatures; in winter, turning it over and laying it on top absorbs heat and retains warmth, reducing the temperature difference between day and night, lowering heating costs, and providing a cooling effect far superior to ordinary shade nets.

2. Ultra-high shading, precise control of light.

The black side is almost completely opaque, creating a completely dark environment; it inhibits the growth of weeds and algae in the greenhouse, while meeting the low-light requirements of edible fungi, short-day flowers, and livestock sheds, eliminating the need for manual weeding.

3. Insect and fungal suppression, reducing pesticide use.

The dark environment inhibits phototactic pests; weeds and algae are significantly reduced, cutting off the host of pests and diseases; 100% UV blocking inhibits the germination of mold and green mold spores, reducing the incidence of diseases.

4. Sturdy and durable, with a long service life.

It features high tensile strength, tear resistance, and puncture resistance, and is resistant to frost, light hail, and coastal salinity. The thickened 5-layer UV-resistant version can be used outdoors for 5-8 years, reducing the labor and material costs of frequent film replacement.

Product Application:

1. Edible Fungus Cultivation (Core Mainstream Scenarios).

Enoki mushrooms, oyster mushrooms, shiitake mushrooms, king oyster mushrooms, wood ear mushrooms, etc.; complete light avoidance prevents contamination of the substrate, yellowing and cracking of the caps, stabilizes temperature and humidity, and enables continuous cultivation year-round.

2. Livestock and Poultry Farming Greenhouses.

Chicken, duck, pig, cattle, sheep, and silkworm sheds; dark environments reduce feather pecking and stress-induced fighting in poultry, provide heat protection in summer and insulation against frost in winter, improving livestock and poultry survival rates and growth rates.

5. Aquaculture.

Shading the tops of shrimp ponds and fish ponds to inhibit the outbreak of blue-green algae and stabilize water quality; can also be used as a seepage-proof lining for aquaculture ponds to prevent water leakage.
