Agricultural Greenhouse Blackout Film Black And White Plastic Film For Crop Protection

Blackout Greenhouse Film Black And White Plastic Film For Crop Protection

Product description:

Black and white film is a double-sided, two-color composite PE functional greenhouse film, made using a three- or five-layer co-extrusion process. One side is white, and the other is black. The two layers are combined with different functional masterbatches and anti-aging additives. Utilizing the reflective properties of the white side and the shading properties of the black side, it achieves integrated temperature control, light regulation, oxygen barrier, and waterproofing.

White side (reflective layer): Contains highly reflective masterbatch to reflect sunlight and infrared rays, reducing heat absorption. When used inwards, it reflects heat from inside the greenhouse for insulation while gently scattering light.

Black side (shading layer): High-concentration carbon black formula with a shading rate of 90%~99.5%, completely blocking ultraviolet and visible light penetration, isolating light, and inhibiting algae, weeds, and bacteria.

Middle substrate layer: Metallocene polyethylene, improving tensile strength, tear resistance, and puncture resistance, combined with UV-resistant additives to extend outdoor service life.

Technical Parameter

Advantages:

1. Strong temperature control, providing warmth in winter and coolness in summer.

In summer, the white side reflects light and provides heat insulation, keeping temperatures 5-10°C lower than ordinary transparent PO film, preventing heat burn to seedlings and heat stress in livestock and poultry.

In winter, the black side absorbs heat, while the inner white film locks in warmth, resulting in superior insulation compared to ordinary shade nets, reducing heating costs.

2. Ultra-high shading, precise light control.

With a shading rate approaching 100%, it can create a completely dark environment:

Inhibits weed growth inside the greenhouse, eliminating the need for manual weeding;

Meets the needs of edible fungi, light-shielding flowers, and low-light livestock and poultry farming.

3. Good airtightness, stable humidity.

The dense, water-impermeable, and low-oxygen-permeable film reduces the need for frequent watering; in silage environments, it can create an anaerobic, light-free environment, resulting in higher-quality fermented feed that is less prone to spoilage.

4. Durable and robust, with a long service life.

With added UV-resistant and anti-aging additives, the premium version can be used outdoors for 5-8 years, far superior to ordinary shade nets and simple PE films, reducing the labor cost of film replacement.

Product Application:

1. Edible Fungus Cultivation (Core Use).

Fungi such as enoki mushrooms, shiitake mushrooms, oyster mushrooms, king oyster mushrooms, and wood ear mushrooms require shade and constant temperature during the mycelial and fruiting stages.

2. Livestock and Poultry Farming Greenhouses.

Full coverage for chicken, duck, goose, pig, cattle, and sheep sheds: Dark environments reduce feather pecking and stress in poultry, improving growth rate; Significantly lowers summer temperatures, reducing heatstroke mortality; Provides insulation and frost protection in winter, improving the farming environment.

3. Aquaculture.

Top coverings for fish and shrimp ponds: Shading inhibits the outbreak of blue-green algae and green algae, stabilizing water quality and reducing water changes; Pond lining membranes: The black, impermeable layer prevents groundwater leakage, suitable for elevated ponds.
