Clear Polythene Sheeting for Greenhouse simply installed, is framed by galvanized tubes. There is no upright in the greenhouse strengthening lighting effects,good for the mechanical operations promoting the land-utilizing ability.
The advantage of Clear Polythene Sheeting for Greenhouse
1. Good light transmittance
The lighting light is astigmatic, the light is soft, and the light transmittance is maintained at a high level
2. Good flame retardancy
Maintains stable performance in the temperature range of -40 to 120 degrees Celsius, and does not soften at high temperatures
3. Corrosion resistance
It has corrosion resistance, acid and alkali resistance, and is suitable for roofing in chemical workshops, such as fertilizer plants, electroplating plants, etc.
4. Impact resistance
It can block the impact of wind, snow and hail and prevent nail holes from swelling, cracking and leaking.

Good light transmission:
Solar panel greenhouses are buildings for lighting during the day. Therefore, in the construction of solar panel greenhouse, it must have good light transmission effect. Light transmittance is one of the most basic indexes to evaluate greenhouse light transmittance. Transmittance refers to the percentage of light passing through the greenhouse to the outdoor light. The light transmittance of greenhouse is affected by the light transmittance of covering materials and the shadow ratio of greenhouse skeleton. The transmittance of greenhouse in different seasons also changes with the change of solar radiation angle. The light transmittance of greenhouse directly affects the growth of crops and the selection of crop varieties. The transmittance of PC sunlight board is the same as that of glass, and the transmittance of high-quality sunlight board can reach more than 85%.
Advantage of single tunnel/PC /Poly carbonate Greenhouse:
(1) Transparency: The transmittance is up to 89%. UV-coated panels do not produce yellowing when exposed to sunlight.
(2) Impact resistance: 150 microns, 200 microns with long life time
(3) UV protection: coated with anti-ultraviolet (UV) coating on the side
(4) Light weight: is light material, which saves the cost of transportation, unloading, installation, and support frames.
(5) Energy-saving: Keep cool in summer and keep warm in winter.
(6) Temperature adaptability: at -35°C, does not soften at 50°C.
