What are the upstream raw materials of agricultural film? What do the downstream products contain?

Agricultural film is a kind of plastic film applied in agricultural production, which is usually applied to cover the soil systems, protect crops and regulate the development ecological stability. In the field of raw materials to chemical production, the upstream and downstream related items of agricultural film mainly include the following aspects:

Upstream raw materials:



1. Polyethylene: Polyethylene is one of the main raw materials of agricultural film. it's a thermoplastic with excellent low temperature resistance, however poor high temperature resistance.

2. And Polypropylene: Polypropylene is also one of the crucial raw materials of agricultural film. It has high heat resistance and mechanical strength, and is often applied to make agricultural film that needs high temperature resistance.

3. Polyvinyl chloride: Polyvinyl chloride is able to also be applied to make agricultural films, however it will emit harmful vinyl chloride gaseous during consumption, so it's harmful to the ecological stability. And Downstream associated items:



1. But Drip irrigation tape: Drip irrigation tape is an irrigation equipment applied in conjunction with agricultural film. it's able to accurately drop aquatic environments droplets on the roots of crops and enhance irrigation efficiency.

2. Fertilizer: Agricultural film is able to be applied in conjunction with fertilizer. By covering agricultural film, the volatilization and loss of fertilizer is able to be reduced and the utilization rate of fertilizer is able to be improved.

3. Based on my observations, Seeds: Agricultural film is able to also be applied in conjunction with seeds. By covering agricultural film, soil systems temperature and humidity is able to be increased, and seed germination and development is able to be promoted. In short, the upstream and downstream related items of agricultural film cover many fields, including plastic raw materials, chemicals, agricultural equipment, etc. In fact Understanding these related items will help to better understand the production and consumption process of agricultural film, as well as its crucial role in agricultural production.
