BACKGROUND ART In recent years, with the aim of adding high value to agricultural products and increasing yields, greenhouse cultivation such as greenhouse cultivation using agricultural vinyl chloride resin films has been actively carried out. By the way, these greenhouse cultivation systems often require ventilation during high temperatures such as summer or daytime to prevent crops from weakening or burning. Many methods of reversal are used. However, in this winding and unwinding work, conventional agricultural vinyl chloride resin films have poor blocking properties, which means that the films do not peel off each other, so the work cannot be progressed or the film is damaged. There was a problem with doing so.

Until now, in order to improve this blocking property, in most cases methylene bis-searlylamide was added in an amount of about 0.1 to 1.0 parts by weight per 100 parts by weight of vinyl chloride resin, but it still remains undesirable. There was a need for something that had sufficient properties and was also effective in improving stickiness and blocking properties.

Regarding weather resistance, it was desired not only to improve the discoloration and deterioration caused by light rays, but also to improve the ability to prevent staining and wear. In other words, farmers use agricultural vinyl fill 1
・There is a tendency to use it for a long time as Amano 1 in the first year, side in the second year, and multi in the second year, so it is necessary to withstand long-term use, and However, there was a drawback that the flexibility of the film became negative.

In addition, the lack of flexibility of the film during the cold season has caused the film to easily tear, which has been a major problem. While the film is buried in soil, it loses flexibility. Similarly, so-called deterioration in the soil became a problem as the usage cycle became longer.
