Plastic Film Densifier for PE/PP Film
Struggling with high energy costs and unstable extruder feeding from wet, fluffy film? Our Plastic Film Densifier creates high-density, dry granules that cut operational expense and improve pelletizing stability.
- Mechanically dewaters and compacts washed PE and PP film into free-flowing granules.
- Typical final moisture reaches 1-3%, reducing downstream drying load and pellet defects.
- Supports 300-1500 kg/h lines and integrates directly with washing and pelletizing systems.
What Is a Plastic Film Densifier?
A Plastic Film Densifier mechanically dewaters and compacts washed PE and PP films into dry, free-flowing granules ideal for feeding a pelletizing extruder. It replaces energy-intensive thermal drying and solves unstable feeding from fluffy film.
Also known as a squeezer dryer or film agglomerator, it integrates high-pressure squeezing and controlled frictional heating to reduce moisture to 1-3% typical while increasing bulk density 3-5x. This directly improves extruder stability and output.
Unlock Peak Efficiency & Profitability
This single machine is the alternative to traditional centrifugal and thermal dryers, delivering practical gains for film recycling and pelletizing lines.
-
Drastically Lower Energy Costs
Reduce energy consumption by over 40%. The mechanical squeezing process lowers dependence on power-hungry hot-air drying systems.
-
Higher Extruder Output
Dense, free-flowing granules feed the pelletizer consistently, reducing clogging and improving throughput.
-
Superior Pellet Quality
Lower moisture helps produce bubble-free recycled pellets with more stable melt quality and higher resale value.
-
Simplified Workflow
This integrated dewatering and densifying solution replaces separate drying stages, saving floor space and maintenance effort.
Plastic Film Densifier: From Washed Film to Pellet-Ready Granules
Our three-step mechanical squeezing and agglomerating process ensures efficient drying without unnecessary thermal load.
-
1. Direct Feeding
Washed film from the recycling line is conveyed into the machine inlet and accepted at high initial moisture.
-
2. Mechanical Squeezing
A high-speed screw applies pressure to force water out through the screen in a highly efficient dewatering process.
-
3. Frictional Agglomerating
Controlled friction generates heat and forms dense, uniform granules that are easier to feed into the extruder.
The Plastic Film Densifier is designed to work in tandem with washing and extrusion-pelletizing components, helping improve output and efficiency across the full line.

Plastic Film Densifier Equipment Overview
Explore the machine layout, wear-resistant screw design, and densifying discharge concept used for stable downstream feeding.
Main Densifying Assembly
The reinforced screw and barrel assembly is designed for continuous squeezing, drainage, and controlled frictional heating, producing dense granules from wet flexible film.
Stable Discharge for Pelletizing
The finished granules discharge in a more uniform, free-flowing form than fluffy wet film, reducing feeding instability and helping pelletizing lines run more consistently.

Why Densifier vs. Centrifugal or Thermal Drying?
A Plastic Film Densifier combines dewatering and densifying in a single step, cutting energy demand and simplifying the line.
| Method | Energy Use | Moisture | Feeding Behavior | Notes |
|---|---|---|---|---|
| Plastic Film Densifier | Low | 1-3% typical | Stable, free-flowing granules | Replaces two machines. |
| Centrifugal Dryer | Medium | 5-10% typical | Fluffy, bulkier | Often needs thermal stage. |
| Thermal Hot-Air Dryer | High | 3-5% typical | May remain fluffy | Higher OPEX and larger footprint. |

Frequently Asked Questions
Clear answers to common questions about film densifiers, operating principles, and recycling line integration.
This machine is a continuous screw-type mechanical squeezer dryer that combines dewatering and densifying in one step. Unlike batch-type pot agglomerators, it runs continuously inline with the washing line, delivering stable output moisture (1-3%) and lower power consumption.
It is designed to handle material coming directly from a thorough washing line. While its primary role is dewatering, it is robust enough for films with residual print and dirt, but final pellet quality still depends on washing performance.
Yes. The densified, low-moisture granules feed consistently into pelletizing lines, improving output and reducing melt pressure fluctuations.
In most cases 1-3% with proper washing and drainage. We generally guarantee less than 5% to cover variations in input material and operation.
The screw segments and dewatering screen barrels are manufactured from wear-resistant alloy steels. Regular inspection of the discharge die and lubrication of the reduction gearbox ensure long service life.
We recommend installing an inline metal detector and magnetic separator on the feeding conveyor before the densifier inlet to prevent tramp metal from damaging the screw assembly.
