Erema Granulation Line
PE film granulation line is a specialized system designed to recycle polyethylene (PE) film waste into high-quality plastic pellets. These pellets can then be used to manufacture new plastic products, promoting a circular economy. Below is a detailed overview of the components, process, and considerations for setting up a PE film granulation line.
LDPE (Low-Density Polyethylene): Stretch film, grocery bags, and packaging films.
LLDPE (Linear Low-Density Polyethylene): Agricultural films, industrial liners.
HDPE (High-Density Polyethylene): Thicker films, such as those used in packaging.
Applications of Recycled PE Pellets
Packaging: Bags, shrink wrap, and films.
Agriculture: Mulch films, greenhouse covers.
Construction: Pipes, sheets, and liners.
Consumer Goods: Containers, toys, and household items.
Conveyor System:
Transports PE film waste to the processing units.
Pre-Washing Unit:
Removes dirt, sand, and other contaminants from the film.
Shredder/Crusher:
Shreds the film into smaller pieces for easier processing.
Extruder:
Melts the shredded film and homogenizes the plastic.
Single-screw or twin-screw extruders are commonly used.
Filtration System:
Removes impurities (e.g., paper, metals, or other debris) from the molten plastic.
Pelletizing Unit:
Cuts the molten plastic into uniform pellets.
Common pelletizing methods include strand pelletizing, underwater pelletizing, or air-cooled pelletizing.
Cooling and Drying System:
Cools and dries the pellets to ensure they are ready for storage or further processing.
Control System:
Automated controls for monitoring and optimizing the recycling process.

Collection and Sorting:
PE film waste (e.g., shopping bags, stretch film, agricultural film) is collected and sorted to remove non-PE materials.
Pre-Washing:
The film is washed to remove dirt, adhesives, and other contaminants.
Shredding:
The film is shredded into smaller pieces to facilitate melting and extrusion.
Extrusion:
The shredded film is fed into an extruder, where it is melted and homogenized.
Filtration:
The molten plastic is filtered to remove any remaining impurities.
Pelletizing:
The filtered plastic is cut into small, uniform pellets.
Cooling and Drying:
The pellets are cooled and dried to prevent clumping and ensure quality.
Packaging and Storage:
The recycled pellets are packaged and stored for use in manufacturing new products.
