PP/PE Film Shredding & Densifying Line
A game-changing technology that transforms dirty, low-value plastic film bales into high-density, reusable material, ready for the next stage of the circular economy.
A Four-Step Transformation Process
The journey begins with a robust shredder designed to break down compacted film bales, preparing them for the next stage.
A wet granulator uses high-speed knives to cut the film into small flakes, while water begins the initial cleaning process.
In a large water tank, PP/PE film floats while heavier contaminants sink, achieving effective cleaning and separation.
Finally, a squeezing dryer uses pressure and heat to remove water and compact the clean film into high-density pellets.

Frequently Asked Questions
Why is densifying plastic film necessary?
Plastic film is very light and fluffy, making it difficult to store, transport, and feed into a pelletizing machine. The densifying process dramatically increases its bulk density and removes moisture, transforming it into a compact, heavy material that is ideal for the next stage of recycling.
What is the final product from this densifying line?
The final product is densified, irregular pellets or chunks, not uniform, perfectly round pellets. This material has a moisture content of less than 3% and is the perfect feedstock for a plastic pelletizing extruder, which will then produce the final, marketable granules.
Can this machine handle dirty, post-consumer film?
Yes, absolutely. This is a complete washing and drying line. The integrated shredding, wet granulation, and sink-float separation stages are specifically designed to remove dirt, sand, and other contaminants from post-consumer or post-agricultural films.
What is the difference between this and a standard pelletizer?
This is a pre-processing line. Its main goal is to wash, dry, and compact the film. A pelletizer is the next step; it takes the clean, densified material from this line, melts it, filters it again, and cuts it into uniform pellets. This densifying line prepares the material for the pelletizer.
Is this a standalone machine or a full line?
We offer both. The squeezing dryer/densifier can be purchased as a standalone machine to upgrade your existing washing line. We also provide the complete, turnkey solution, including the shredder, granulator, washing tank, and densifier, all tailored to your capacity needs.
