PEP Three Layer Low Light Plastic Film Greenhouse For Mushroom
Product describe:
As the greenhouse is a daylighting building, the transmittance is the basic index to evaluate the transmittance of the greenhouse.Transmittance is the percentage of the amount of light that penetrates into the greenhouse versus the amount of light outside.The transmittance of greenhouse is affected by the transmittance of greenhouse cover material and the shadow rate of greenhouse frame.In addition, the transmittance of the greenhouse will change at any time with the different solar radiation angles in different seasons.The transmittance of greenhouse directly affects the growth of crops and the selection of crop varieties.General plastic greenhouses number is 50% ~ 60%, glass greenhouses transmittance is 60% ~ 70%, daylight greenhouses can reach more than 70%.
This product is white on the outside and black on the inside.It is used in summer and autumn.When it is covered, the white side is up and has a strong ability to reflect light.The black side prevents light from passing through, providing shade and cooling.It's a lot lower light
Greenhouse Framework:
Our polyethylene film greenhouse frame is hot dip galvanized steel structure;it's a stable structure, high intensity;the assembly style is without welding points and excellent anti-corrosion,the frame steel size can be customized design ,the steel is a high quality material which is good aging resistance;the steel has a long life time and the frame assemble easily.

Greenhouse Covering:
PEP black and white functional film, using advanced five-layer co-extrusion technology, film width 8-18 meters, thickness 12 silk, 1 square meter 100 grams, raw materials using pure masterbatch and adding UV anti-aging agent, extended Service life, service life is 3-5 times that of ordinary shade nets.
Use the black side facing outwards in the winter to absorb the frost and snow from the surface. The thickness is 12 wires. PEP black-and-white functional film and white-faced internal energy can block and reflect most of the infrared (thermal energy) inside the shed to radiate to the outside of the shed, thus playing a thermal insulation role.
