High-Performance PO Greenhouse Film for Blueberry & Grape | Diffused Light, Anti-UV & Long Service Life

Blueberry Diffused PO Film – Core Functions

Blueberry cultivation requires precise light management. Traditional greenhouse films often cause excessive direct sunlight, leaf scorch, fruit sunburn, and rapid film aging.
Our Blueberry Diffused PO Film is specifically engineered with high light transmittance and high haze to optimize plant growth while extending film durability.

1. High Light Transmittance

High PAR (Photosynthetically Active Radiation) transmittance is essential for blueberry photosynthesis and healthy growth.
Even under high haze conditions, this specialized film maintains over 92% light transmittance, significantly improving photosynthetic efficiency and crop vitality.

2. High Haze (Diffused Light)

Haze levels can be precisely controlled, reaching up to 90% or higher.
This enables uniform light distribution throughout the greenhouse, reducing shadows and preventing concentrated direct light that can damage blueberry leaves and fruits.

3. Anti-Sunburn Protection

By converting harsh direct sunlight into soft diffused light, the film eliminates high-light hotspots and dark zones inside the greenhouse.
Blueberry leaves and fruits receive balanced light from top to bottom, effectively preventing sunburn spots, fruit depressions, and surface damage—greatly enhancing fruit appearance, quality, and market value.

4. Extra-Long Service Life

Formulated with 5-year-grade masterbatch additives, the film is designed for strong UV environments and diverse climates.
Its superior anti-aging performance ensures a service life far longer than conventional greenhouse films.

5. UV Protection

The film effectively blocks 300–380 nm ultraviolet radiation, which helps suppress pests such as thrips and whiteflies.
It also inhibits the formation of fungal spores like gray mold, providing efficient disease and pest control while reducing chemical dependency.

6. High Strength & Durability

With over 60% metallocene materials, the film exhibits exceptional toughness and tear resistance.
Wind resistance and disaster tolerance are improved by two levels, significantly reducing risks during long-term use.

Long-Life PO Film for Grapes – Core Functions

Grape cultivation commonly faces sulfur corrosion and rapid film degradation due to frequent sulfur fumigation for disease control.
Our Long-Life Grape PO Film is engineered to resist sulfur damage, extend service life, and fully meet the growth requirements of grapes.

1. Anti-Sulfur & Corrosion Resistance

Sulfur fumigation is widely used to control powdery mildew and downy mildew in grape production.
Ordinary PO films are easily corroded by sulfur gas, leading to embrittlement and reduced light transmittance.
This specialized film incorporates anti-sulfur agents, effectively resisting sulfur erosion and maintaining film integrity and optical performance—ensuring uninterrupted photosynthesis.

2. Superior Anti-Aging Performance

Produced using multi-layer co-extrusion technology and enhanced UV stabilizers, the film withstands intense ultraviolet radiation in high-altitude regions such as Kunming and Xichang.
Its service life is 1–2 years longer than standard PO films, significantly reducing labor and replacement costs.

3. Optimized for Grape Growth

With light transmittance above 90%, the film supports grape flowering, fruit set, and berry enlargement.
Excellent heat retention and moisture control help stabilize greenhouse temperature and humidity, minimizing day–night temperature fluctuations that can cause fruit cracking or quality decline.
