Film greenhouses are buildings that use plastic film covering materials as all or part of the surrounding structure materials, and can be used to cultivate plants in winter or other seasons that are not suitable for open-field plant growth.  Plastic greenhouses can make full use of solar energy, have a certain insulation effect, and can adjust the temperature and humidity in the greenhouse within a certain range through rolling films.  Plastic greenhouses are generally not heated indoors and rely on the greenhouse effect to accumulate heat.  The lowest temperature is generally 1~2°C higher than the outdoor temperature, and the average temperature is more than 3~10°C higher.  The light transmittance of plastic greenhouses is generally 60% to 75%.  In order to ensure a basic balance of average light throughout the day, the layout of the greenhouse is mostly extended from north to south.
