Blackout Poly Film White/Black 50'x150'

This white-and-black blackout polyethylene film measures 50 by 150 feet and is approximately 5 mil thick. The layered agricultural film is intended for high-opacity applications such as photoperiod control, reflective greenhouse surfaces, silage covering, and stale-seedbed preparation. The white side reflects light and heat, while the black side limits light transmission.

• 50 by 150 feet roll
• White surface and black backing
• Approximately 5 mil thickness
• Multi-layer construction for outdoor agricultural use

This is the largest format in the group; plan lifting, unrolling, and anchoring before opening it, and use enough people or equipment to prevent dragging and punctures. Measure the structure or ground area before ordering and allow material for fastening and overlap. Support the film so wind cannot whip against sharp edges, use attachment hardware suited to polyethylene, and avoid excessive tension. Blackout performance depends on sealed seams and edges; inspect for punctures after storms or equipment movement. Keep folded film away from heat and flame, and store unused material dry and protected from rodents and sunlight.
