White plastic film has obvious thermal insulation effect, and hot air can be absorbed and discharged over a large area. Because white materials can insulate well and heat is easy to dissipate, the environment should be kept at a low temperature. During construction operations, there will be no large temperature difference between morning and evening. In addition, white plastic film can also prevent damage to the white film by fallen objects, which plays a good protective role. The greenhouse adopts a thickened plastic film design to achieve the purpose of small heat conduction, reduced damage, and rapid climate change (large temperature difference between morning and evening reduces warming, and small temperature difference between morning and evening increases warming and precipitation). According to relevant data, greenhouses use plastic film for thermal insulation, some of which have a target of 80% shading, a few have 60% shading, and can reach about 80% shading, reducing direct sunlight and protecting from insect pests. The plastic film insulation layer should meet the operating conditions and be able to withstand its deformation within a reasonable range.
