After that, the wet plastic film sheet will be dehydrated and will be melted as a mushy shape with electromagnetic heating, long strips will be created by the plastic granulator machine, then those long strips will be cooled in a cold water sink, at this moment, they will be cut by the pellet cutting machine, at last, the pellets will be stored in the storage bin.

Due to the characteristics of PVC material, it is best not to wash it in the process of recycling PVC plastic film. If a water washing step is necessary, the raw materials must be dried. And in the processing process, chemical ingredients need to be added. Generally, the quality of plastic particles is related to the water content of raw materials. Too much water content will seriously affect the quality of plastic particles.
