1 cold insulation performance: replace the film, avoid blindly choose low prices, promotional items. The price of blindly pursuing low-price film is to replace the new film every year. With manpower and material resources, the cost is not low, and the total cost of the integrated film is not much cheaper. Therefore, it is best to choose durable, high quality, high thickness, and high tensile strength of the film. Covering such a shed film, the temperature in the deep winter festival can be 2° C. to 3° C. higher than that of the conventional shed film. 2 tear strength: tear strength refers to the transverse film, longitudinal tensile strength and toughness. Tear-resistant films with high tear strength do not cause tears or tears in the winter or spring season. 3 light transmission performance: the winter and spring season dust, with hazy weather, air humidity, the 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. 4 fog atomization performance: shed film is divided into drop film and no 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.
