GGPO® Diffused Film FL686H 150 MICRONS

FL686H is a 150μm (6 mil) 5-layer co-extruded light-diffusing cover engineered as a high-performance solution in our 5 layer greenhouse film selection. Designed specifically to transform harsh direct sunlight into uniform, scattered light, FL686H prevents canopy shading, reduces crop stress, and lowers ambient temperature spikes. Combining soft light diffusion with advanced anti-drip and anti-fog performance, this 3rd-generation PO film is ideal for commercial growers seeking balanced light distribution and superior crop quality in high-radiation regions.

Key Performance Benefits

• High-Efficiency Light Diffusion: Converts strong direct radiation into soft, multidirectional PAR light, penetrating deep into dense crop canopies and preventing top-leaf scorch.

• 150μm Standard Commercial Gauge: Engineered with 5-layer co-extrusion technology for reliable tensile strength, tear resistance, and multi-year structural stability.

• Super Long Anti-Drip & Anti-Fog Coating: Specialized inner surface coating prevents condensation droplets, safeguarding foliage from fungal diseases while preserving optical transmission.

• UV-Open & Bee-Friendly Structure: Formulated to permit essential UV spectrum pass-through, promoting natural bumblebee navigation, effective pollination, and rich crop pigmentation.

• Thermal Retention & Chemical Resistance: Provides high thermal insulation to minimize heat loss overnight, fortified with advanced UV stabilizers to resist pesticide and sulfur breakdown.

Recommended Crops and Applications

FL686H is ideal for heat-sensitive, high-canopy, or shade-sensitive crops and intense sunlight geographic areas:

• Fruiting Vegetables: High-density tomatoes, cucumbers, peppers, and eggplants requiring deep canopy light penetration.

• Floriculture & Nursery: Premium cut flowers (roses, orchids, gerberas) susceptible to petal burn under direct sun.

• Geographic Suitability: Highly recommended for regions with high solar radiation, hot summer climates, and intense sunlight zones.

How This Model Compares

While super-clear models optimize total direct PAR light in low-sunlight regions, FL686H excels in high-radiation climates by eliminating hot spots and shade gaps. For heavier snow load zones or extreme weather requirements, explore 180μm (FL786I) or 200μm diffused models. For maximum structural durability in high-wind zones, consider pairing with woven greenhouse covers.

Quality Control and Test Documentation

Manufactured under strict ISO-certified manufacturing protocols, FL686H is rigorously tested prior to global delivery:

• Spectrophotometer testing to verify precise PAR light transmission and haze ratio percentage.

• Tensile strain (26 MPa) and dart-drop impact testing per production batch.

• Supplied with a certified Technical Data Sheet (TDS) and factory quality inspection certificate upon request.

Installation and Correct-Side Orientation

To ensure maximum anti-drip longevity and structural performance, follow these installation practices:

• Correct Orientation: The coated anti-drip surface must face inside the greenhouse. Confirm orientation by checking the printed directional logos on the film.

• Coating Surface Care: Prevent the coated side from dragging or rubbing against rough ground or metal frames during unpacking and installation.

• Recommended Mounting Hardware: Secure using locking profiles and wiggle wires to avoid friction and structural wear.

• Corrosion Protection: Do not install directly over rusted structural steel. Clean, treat, or paint frames prior to covering.

• Roof Geometry: Ensure continuous slope without concave dips or sagging areas where rainwater can pool.

• Installation Tension & Timing: Install during cooler morning or evening hours. Apply firm tension in winter and lighter tension in summer setup.

• Initial Humidity Activation: Maintaining internal greenhouse humidity near 70% during initial installation helps activate peak anti-drip performance.

Warranty Conditions

FL686H comes with a factory-direct pro-rated commercial warranty:

• 2-Year Warranty: Central Africa, Middle East, and high-UV extreme climate zones.

• 3-Year Warranty: East Asia, Southeast Asia, North/South America, Australia, and Europe.

Diffused Greenhouse Film 150 Micron FAQ

What is the main advantage of choosing FL686H diffused film over clear film?

FL686H diffuses direct sunlight into soft, scattered light, preventing top-leaf burn, lowering greenhouse temperatures during hot peak hours, and allowing light to reach lower leaves for even growth.

How do I know which side faces inward toward the crops?

Check the printed text and logo marks on the diffused greenhouse film surface. Ensure the text reads correctly from inside the greenhouse so that the inner anti-drip coating layer faces your crops.

Does FL686H interfere with bumblebee pollination?

No, FL686H features a UV-open formulation that allows necessary natural UV spectrum wavelengths through for unhindered bee navigation and efficient pollination.
