In order to prolong the service life of agricultural plastic film and achieve greater economic benefits, it is necessary to make reasonable choices, correct uses, good storage and maintenance according to the actual situation of the region. Here's a quick overview of how to select, use and maintain agricultural plastic films.

Selection of agricultural plastic films 

There are different varieties and specifications of plastic films according to the original method, molding method, use, width and thickness. When purchasing plastic film, a reasonable choice should be made according to the climatic conditions and use of the region. For example, thick plastic films are suitable for use in areas north of the Yellow River; The thin plastic film is suitable for use in the south of the Yangtze River; The 0.1 mm thick plastic film is suitable for the outer layer covering of the plastic film greenhouse; The plastic film with a thickness of 0.065 mm or 0.075 mm is suitable for rice seedling raising, the plastic film for mulching is preferably wide, and the plastic film for packaging is preferably blown film with a thickness of more than 0.1 mm.

When choosing plastic film, we should also pay attention to the safety performance of plastic filmGenerally, agricultural plastic film will not produce harmful gases, and there is no adverse impact on the contact with people, animals and crops, which can be said to be safe. However, if the plastic film manufacturing plant accidentally uses some volatile auxiliary materials in production, such as adding diisobutyl trimthalicate to the polyvinyl chloride plastic, in the process of use, it will gradually volatilize harmful gases from the plastic film, so that crops produce "poisoning" phenomenon, plant growth is slow, and leaves appear yellow and white spots, wilting, etc. At this time, it is necessary to quickly ventilate the greenhouse, water the crops, and replace the "toxic" plastic film in time to avoid the spread of the element. The solution to this problem is, first of all, the manufacturer should strictly control and carefully select auxiliary materials to prevent "toxic" plastic film from leaving the factory; The total number of users should be inspected frequently, and pay attention to the growth and changes of crops in the plastic film greenhouse, and take measures immediately once there is a problem. In addition, agricultural plastic films are directly used in agricultural production, not to package food, beverages, medicines, etc.

Protection of agricultural plastic book films 

In the process of using plastic film, under the action of light, heat, machinery, chemicals, microorganisms, etc., it is often soft and hard, and the light transmittance decreases, and the color gradually changes to brown and yellow, and finally, even rubs it into pieces by hand, this phenomenon is called the "aging" of plastic film. The longer the plastic film is resistant to aging, the longer its service life will be. The aging resistance of plastic film is determined by the film formula and processing technology of the manufacturing plant, but practice has proved that the same plastic film, in a similar climatic environment, due to the different use and maintenance methods, the aging resistance time is not the same. It can be seen that correct use and proper maintenance are two important links to extend the service life of plastic films.

The agricultural plastic film is mainly used for crop seedling raising, and the manufacturing plant mainly considers its formula,
