Cold insulation performance
Replace the film, avoid blindly choosing low prices, promotional items. It is best to choose durable, high quality, high efficiency, thickness increase and tensile strength of the film.
Tearing strength
Tear strength refers to the transverse and longitudinal tensile strength and toughness of the film. Tear strength of the shed film, spring wind will not cause it to tear or tear light.
Light transmission performance
The dust in the spring of our province is relatively large, and the shed film will be covered with a layer of dust. If it is a light-permeable film, the surface is smooth and dust-free, or it is very clean after being washed with rain or snow. Transparency directly affects the light intensity and temperature of the greenhouse.
Droplet atomization performance
The film is divided into drop film and drop film. The quality of the high-quality filming of the film is good, and no mist is formed in the shed. When the humidity is high, the water vapor flows down the film along the film and back to the ground, and the mist elimination function is excellent. At the same time pay attention to the shed, the good shed film has positive and negative points, do not reverse the anti-fog layer to the outside.
