What are the main production processes for agricultural plastic films?

The main production processes for agricultural plastic films include resin selection, extrusion, cooling, cutting, and winding. Resin selection involves choosing the appropriate plastic material, such as polyethylene or polypropylene. Extrusion is the process where the selected resin is melted and forced through a die to form a continuous film. Cooling is essential to solidify the film after extrusion. Cutting involves trimming the film to the desired width and length. Finally, the film is wound onto rolls for packaging and distribution. Quality control checks are also performed throughout these processes to ensure the film meets specific agricultural requirements.
