Tearable composite film is more and more widely used in agriculture. Under the guidance of the general national economic policy of "agriculture based, industry oriented", agricultural plastic film has developed rapidly. In China, plastic film has been applied to agricultural production for more than ten years. At first, it was used to raise rice seedlings, with remarkable yield increase effect. Later, it was gradually extended to sweet potato, cotton seedling, vegetable cultivation, tobacco, ginseng, silkworm production, etc., and achieved results.

Agricultural plastic film is not only used in agricultural production, but also used to store fruits and vegetables. It can not only delay the ripening process of fruits and vegetables, reduce water evaporation, prevent decay, but also maintain their freshness. From the comparison of the experiment of apple storage, the natural consumption is below 0.7% after five months of storage with plastic film packaging. Unused natural consumption can reach 5. 83%。

Indeed, plastic film has become more and more widely used in agriculture and plays an increasingly important role. Like chemical fertilizers and pesticides, it has become an important means of agricultural production in agricultural production. The poor and lower middle peasants said well that agricultural plastic film is a good "partner" in agricultural production and a "film for increasing production" in agricultural production.

At present, there are two kinds of plastic films used in agricultural production: one is called PVC film, and the other is called polyethylene film. The amount of PVC film is large. PVC agricultural film can be divided into two categories according to its use; One is PVC film for agriculture, the other is cold resistant PVC film for agriculture. With the expansion of the application scope of film in China and the requirements of different crops, there are also black film, colored film, drip free film and drip film.
