Recycling and reprocessing methods of plastic film
The processing methods of plastic films of different materials are slightly different, but most of them need the following steps.
First of all, the raw material needs to be crushed and washed easily by a crashing and cleaning machine, and then they will be washed thoroughly in a sink. After that, the wet plastic pellets 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.
PVC plastic film recycling production line
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.

Raw material related knowledge of plastic film recycling line
The common kinds of plastic are PE, PP, and PVC, those are widely used in our daily life. Therefore, learning the main performance and use of the above three materials are important.
Polyethylene (PE) has excellent processing and use properties, and is the most widely used variety in synthetic resins, and its production capacity has long ranked first among all plastic varieties. Polyethylene resins mainly include low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), and high-density polyethylene (HDPE).
PE can be blow-molded to make various bottles, cans, industrial tanks, barrels, and other containers; injection molded to make various pots, barrels, baskets, baskets, baskets and other daily containers, daily sundries, and furniture, etc.; extrusion molding Manufacture all kinds of pipes, straps, fibers. The two most important consumer areas are pipes and films，
The density is small, the raw material is transparent and light in appearance, non-toxic and tasteless, and has high strength and elasticity. It has high-temperature resistance of 100~120 degrees.
PP commonly used in plastic lunch boxes, water cups, food packaging boxes and other products.
PVC is also a colorless and transparent hard material construction of downpipes, plastic steel windows, credit cards, etc. are all hard PVC.
But PVC can be added with a lot of plasticizers, and then it can be made into soft PVC. Ordinary wire sheaths, disposable infusion tubes, some inflatable toys, soft curtains, transparent plastic table mats called soft glass sold in supermarkets, etc. are all soft PVC. PVC can also be colored.
The necessity of plastic film recycling
- Plastic production is made from petroleum，burning plastic can produce a lot of carcinogens. The number of people getting cancer is always incredible in the place where burning plastic. Therefore, dealing with plastic products in a proper way has no time to delay.
