Biodegradable and ECO-friendly PVOH Shading Screen

PVOH shading screen is made of PVOH film and polyester yarn through knitting. Nowadays, PVOH shading screen is widely used in agricultural greenhouses in many developed countries as it can not only reduce ultra-strong sun ray which may burn the crops, but also reserve the heat from the ground and keep the temperature inside the greenhouse. It provides better ambient condition for crops. Moreover, PVOH shading screen is soft, easy to use and compatible with mechanical device.
Advantages of Biodegradable and ECO-friendly PVOH Shading Screen
High transparency, anti-static, dust-proof
PVOH film has high transparency and luster which is the best choice of the shading screen. Dust free will gather as PVA film is anti-static so that high light transmission rate can be maintained stable.
Excellent temperature maintenance
PVOH film has excellent property of ultra-infrared ray prevention. The heat ray from the sun shine can be controlled so that the crops will not be burned, in addition, PVOH film can reserve the heat from the ground and keep the temperature inside the greenhouse. It provides better ambient condition for crops and save energy (Please refer to the right bottom picture).
Good moisture permeability, no fog & water droplets
PVOH shading screen has good property of moisture permeability and maintain the moisture balance. No fog and water droplets may form on the film surface, hence crop leaf damage can be avoided.
Great anti-aging
PVOH shading screen is sustainable under the temperature range of -60℃~130℃ PVOH shading screen has good property of small Light transmission change and has long working life due to its great anti-aging property.
Eco-friendly and fully biodegradable
PVOH film is a kind of eco-friendly material and it is fully biodegradable.
