Anti-drip and anti-fog EVA film with high light transmittance for outdoor use

Product description:

EVA greenhouse film is a functional greenhouse film primarily made from ethylene-vinyl acetate copolymer (EVA), with the addition of anti-aging, anti-drip, anti-fog, thermal insulation, and light-conversion agents, and produced through blow molding. The higher the vinyl acetate (VA) content, the better the film’s thermal insulation, light transmission, and anti-drip performance. This product falls into the mid-to-high-end category of agricultural greenhouse films, with performance characteristics falling between those of standard PE films and PO films; it is the mainstream material for winter-warm greenhouses.

Technical Parameters:

Advantages:

1. Excellent thermal insulation: Its infrared blocking capability far exceeds that of pure PE film. It effectively traps heat inside the greenhouse at night and reduces the temperature difference between the interior and exterior during winter, making it ideal for protecting overwintering crops from frost.

2. Gentle light transmission and high photosynthetic efficiency: High light transmittance and moderate UV penetration ensure uniform fruit coloring; when used in conjunction with light-conversion agents, it effectively converts light energy, thereby improving yield and quality.

3. Long-lasting anti-drip and anti-fog effects: EVA is highly polar and has good compatibility with anti-drip agents, resulting in long-lasting anti-fog and anti-drip effects that significantly reduce the incidence of downy mildew and gray mold in high-humidity environments.

4. Good low-temperature flexibility and toughness: It does not harden or crack easily in low winter temperatures, making it less prone to damage during installation and removal in cold northern winters, and providing greater wind resistance.

Product Application:

1. High light transmittance and high photosynthetic efficiency: High light transmittance allows for moderate UV penetration, resulting in uniform fruit coloring; when combined with light-converting agents, it can convert light energy, increasing yield and improving quality.

2. Long-lasting anti-drip and anti-fogging effect: The anti-drip agent has good compatibility, providing a long-lasting anti-fogging and anti-dripping cycle, significantly reducing diseases in high-humidity environments.

3. Resistant to chemical corrosion: Resistant to fertilizers and pesticides, less prone to powdering and delamination, with a service life superior to ordinary long-life PE films.

4. Minimal light transmittance attenuation: Light transmittance decreases slowly under prolonged sun exposure, ensuring stable light levels inside the greenhouse and unaffected crop growth in the mid-to-late stages.
