Plastic film recycling production line
What are the common plastic films?
In daily life, you will see plastic films of various materials, such as beverage packaging films, frozen food packaging films, medical plastic films, and fresh-keeping films. They are made of PET, PC, PVC, PP, PE, etc.
- Among them, PE film is the most widely used plastic packaging film, which has good moisture resistance, heat shrinkability and toughness. It is often used in food, clothing, fertilizers, industrial products, packaging materials and agricultural films.
- PP film has the characteristics of high strength, good heat resistance and good electrical insulation properties. Commonly used in the outer packaging of cigarettes, medicines, frozen foods, and woven bags.
- PVC film has a large market in the field of non-food packaging and can be used to make tablecloths, curtains, raincoats, etc. Because it is easy to print, it can be used to make both transparent and printed products.
Recycling and reprocessing methods of plastic film
The processing methods of plastic films of different materials are slightly different, but most of them need to be crushed — washed — dehydrated — melted, reshaped — cooled — cut — stored.
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.
Relevant equipment for PVC plastic ilm recycling
No cleaning: plastic crusher — plastic pellet extruder — cooling tank — pellet cutting machine
PP plastic film recycling production line
Woven bag is a more common kind of PP soft material. Some woven bags are dirty and need to be washed twice before entering the next processing step.
Relevant equipment for PP plastic film recycling
Crusher — washing machine — dewatering machine — washing machine — dewatering machine — plastic pellet machine — cooling tank — pellet cutter
PE plastic film recycling production line
There is a special type of PE plastic film, namely cling film. In supermarkets, frozen food or fresh vegetable packaging is usually covered with plastic wrap. However, this type of cling film is often affixed with a label. At this time, a paper-plastic separator is required to separate the label paper and the cling film.
Recycling equipment for cling film
Plastic Crusher — Paper-Plastic Separator — Cleaning Tank — Dehydrator — Plastic Granulator — Cooling Tank — Pelletizer

Related machine introduction
There is a rotating cutter inside the crusher. The cutter is specially treated to crush the material into small pieces in a short time. The blade can be re-sharpened for durability. This machine has a low working noise and a wide range of applications. It can be used not only for plastic films but also for rigid plastics such as plastic bottles and plastic sheets.
The cleaning tank is mainly used to remove dirt on plastic materials. There are several models to choose from. There are multiple agitators installed on the upper part of the machine, which can make plastic materials cleaner. The bottom of the conical machine is equipped with a screw pushing device, which can automatically discharge sewage, save labor and save water resources.
The dehydrator is divided into a vertical dehydrator and a horizontal dehydrator. usually. The horizontal dehydrator has better dewatering effect, but it needs to be matched with relevant material conveying equipment. The inside of the vertical dewatering machine is a screw feeding device, which uses a strong centrifugal force to throw out the water in the material during the screw conveying.
Plastic pellet extruder
The dried material enters the plastic pellet machine from the feeding port. The material is melted under the heating of the heating ring. The molten material flows out from the outlet of the main machine and then enters the auxiliary machine. Under the extrusion of the auxiliary machine, it is extruded from the die at the head of the machine.
The cooling tank is mainly used for cooling the material extruded from the plastic pellet machine. It is made of stainless steel, which can ensure no rust and corrosion during long-term contact with water.
The plastic pellets that are melted and extruded by the plastic pellet machine are in the shape of long strips. In order to facilitate storage and secondary use, plastic pellet cutters are also required to cut the plastic strips into plastic pellets.
The prepared plastic granules can be directly packed in woven bags or put in storage bins. There is a pump in the lower part of the storage bin, which can continuously suck plastic particles into the inside of the machine.

Common problems of plastic film recycling production line
- Can I use the same production line to process PP and PE materials?
A: This production line can be used to process multiple materials, but the same production line can only process one material to avoid affecting the purity and quality of the final product.
- What is the power consumption of the entire production line?
A: The power consumption is about 500 degrees when processing one ton of material.
- What are the materials of the granulator screw and die?
A: 38 Luo manganese steel / 40 Luo
- What is the heating method of the granulator?
A: Electromagnetic heating, cast aluminum heating ring, ceramic heating ring, quartz tube heating ring, etc., selected according to raw material processing needs and customer requirements
- How to make different colored plastic particles?
A: Add pigment when granulating, formula can be provided after order
