Plastic Film Pelletizing Machine is a plastic film recycling machine used to recycle plastic films into pellets. This machine is a part of the plastic recycling process, where post-consumer or post-industrial plastic films, often in the form of scraps or waste, are converted into manageable pellets. It can be reused in various manufacturing processes.
How Does a Plastic Film Pelletizing Machine Work?
Many people want to know the plastic film granulation process. The working principle of a plastic film pelletizer is simple. The machine melts the plastic film at a high temperature, forces it through a mold, and then uses a pellet cutter machine to cut it into small plastic pellets.
Detailed Plastic Film Pelletizing Process
Feeding
The crushed plastic film is fed via a conveyor belt into the machine inlet. By the way, if you want to get crushed plastic film, you need to use a plastic film shredder.
Melting
The plastic film will then be melted in the plastic film extruder, which is a heating chamber. The extruder is a heating chamber. Customers can choose between electromagnetic heating, ceramic heating, iron heating, and other heating methods.
Extrusion and Pelletization
The molten plastic is forced through a die, which is a small opening that shapes the plastic into strands.
Cooling
Water is used to cool the strands of plastic.
Cutting
The strands of plastic are cut into small pellets with a plastic pellet cutter.
Plastic Film Granulator Design
A plastic film granulator is mainly composed of a feed inlet, screw, heating device, extrusion chamber, discharge die head, motor, reducer, and other structures.
The body of the plastic granulator is made of alloy steel material, which is characterized by high heat resistance, high wear resistance, and corrosion resistance.
The screw inside the machine is the device used to push the material forward. The screws are also made of corrosion-resistant and high-strength alloy steel.
At Shuliy Recycling Machinery, we have three types of discharge die heads such as electric gear die heads, hydraulic die heads, and automatic slag filters.
The machine head is fitted with a grinder alignment device to correct the concentricity of the discharge opening and the die head.
The machine is also equipped with a cooling device to eliminate excess heat generated by the rotating friction of the screw. This prevents excessive temperatures that can cause some unwanted problems.

What Are the Benefits of Using a PE Film Granulator?
- Versatility in Recycling: PE film granulators can handle a wide range of plastic film types, including polyethylene, polypropylene, and polyethylene terephthalate, making them versatile recycling solutions.
- Reduced Plastic Waste: Plastic film pelletizing machines play a crucial role in minimizing plastic waste. By converting plastic film scraps into usable pellets, these plastic film pelletizing machines divert plastic from landfills and incinerators, reducing their environmental impact.
- Production of New Products: Recycled plastic pellets obtained from pelletizing machines serve as valuable raw materials for manufacturing new plastic products. This reduces the demand for virgin plastic, further conserving natural resources.
Applications of Recycled Plastic Pellets
Manufacturing of Plastic Products: Recycled plastic pellets made by plastic film granulators are used to create a wide array of plastic products such as containers, bottles, packaging materials, and household items.
Construction Materials: They are utilized in making construction materials like pipes, decking, panels, and insulation materials.
Automotive Parts: Recycled plastic pellets are employed in producing various automotive components such as bumpers, interior parts, and trim pieces.
Textiles and Fibers: They can be used in the production of synthetic fibers for clothing, carpets, upholstery, and other textile applications.
Films and Sheets: These pellets are utilized in manufacturing plastic films and sheets used in packaging, agriculture (mulching films), and industrial applications.
How to Operate a Plastic Film Pelletizing Machine?
Do you want to know how to make plastic pellets with this pp/pe film pelletizing machine?
Cleaning and Preparing the Machine
Before starting the machine, make sure that it is clean and free of any debris. Inspect the machine for any damage or loose parts.
Loading the Plastic Film
Load the plastic film into the feed hopper of the machine. The feed hopper is usually located at the top of the machine. If using a conveyor belt, ensure that it is properly aligned with the hopper.
Starting the Plastic Film Recycling Granulator
Turn on the power switch of the plastic film recycling granulator. Set the desired parameters such as temperature, pressure, and cutting speed according to the specific type of plastic film being recycled.
Monitoring the Machine
Monitor the plastic film pelletizing machine during operation to ensure that it is running smoothly. It can ensure pellets are being produced correctly. Check for any unusual noises or vibrations, and adjust the parameters as needed.
Emptying the Pellets
Once the machine has finished producing pellets, turn off the power switch and allow the machine to cool down.
The Cost of Plastic Film Pelletizing Machine?
The cost of a plastic film pelletizing machine can vary depending on several factors, including the size and capacity of the machine, the features and options included, and the brand of the machine. In general, small, single-stage pelletizing machines can be purchased for as little as a few thousand dollars, while large, two-stage machines can cost upwards of several hundred thousand dollars.
Please note that the actual cost of a plastic film pelletizing machine may vary depending on the specific requirements of the buyer. If you want to know the exact price, please contact us and we will recommend the right machine according to your requirements.
How to Maintain Plastic Film Granulator?
Cleaning
Perform daily cleaning to remove any residual plastic film from the feed hopper, extruder, die, and pellet discharge bin. This helps prevent blockages and ensures consistent production.
Inspection
Conduct a daily visual inspection for any signs of wear or damage, such as loose bolts, worn belts, or leaking seals. Promptly address any issues to prevent further deterioration.
Lubrication
Check and replenish oil or grease levels according to the manufacturer’s recommendations. Proper lubrication ensures smooth operation and reduces wear on moving parts.
Tightening and Adjustments
Tighten any loose bolts or screws, and adjust belts or chains to maintain proper tension. This ensures optimal machine performance and reduces the risk of mechanical failures.
Electrical Inspection
Inspect electrical connections and components for any signs of damage or looseness. Ensure that all wiring is properly secured and that there are no exposed wires.
