The greenhouse film has a service life, and the years of use of different materials are also different. Due to the influence of high temperature and strong light rain erosion and other factors, the aging speed of the agricultural film is relatively fast, and it needs to be replaced in time to prevent damage.

High temperature stuffy sheds cause relatively great damage to the shed film. According to the understanding, if the stuffy shed is more than one month in the high temperature season, the shed film will be seriously aging, the light transmittance will be reduced, the thermal insulation will be reduced, and it is easy to break.

First, the airtightness of the greenhouse needs to be checked. When the sealing condition is good, there will be no problem if the air pressure inside and outside remains the same. To prevent this, a thin film can be produced on the bow.
