As one of the main greenhouse covering materials, agricultural film plays an important role in building high-yield, high-quality and high-efficiency agriculture. Observe the following points when distinguishing the quality of agricultural film:
1. Transparency of highly transparent agricultural film, and the general agricultural film color white, fog.
2. The high-quality agricultural film has good weather resistance, and in the cold winter, it still maintains good softness, while the general agricultural film is hardened, and there is a white mark at a slight discount.
3. Durability Agricultural film tensile strength is high, such as cutting a small strip, stretching can be extended 6 to 7 times, still will not break, general agricultural film is crisp.
4. When the drip-proof membrane is sprayed with water, the water droplets are flaky and flow down the membrane wall.
5. When the heat-insulating film is stretched, the place where it is stretched will turn white, and if it is repeatedly pulled, it will be transparent again, which means that the heat-retaining film will show high heat preservation, and the general film will not have such effect.
6. Anti-settling plastic film is not sticky, film laying is convenient, and water spray film surface, the collection of water is small water droplets, and the general agricultural film is strong, the film and the film will stick together, not easy to open, easy to dust .
7. When the agricultural film with good light transmission passes through the sunlight, the light is softly dispersed, and the general agricultural film has a direct feeling.
