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.
Applications & Materials
The Plastic Film Densifier handles post-consumer and post-industrial streams and prepares them for stable extrusion.
PE film (LDPE/LLDPE), printed film, stretch film, and shrink wrap.
PP woven bags, raffia, and jumbo bags after proper washing.
Agricultural film and greenhouse film with residual moisture.
Label film offcuts and packaging film reclaim.
Integration with Plastic Film Washing Line and Plastic Pelletizers.
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. |

Your Questions Answered
How is this different from a standard agglomerator or densifier?
This machine is a specialized dewatering and pre-processing unit. Its main goal is to dry material correctly for pelletizing with more controlled moisture and density than a simple agglomerator.
What level of film contamination can this machine handle?
It is designed to process material coming from a proper washing line. It can tolerate residual print and dirt, but final pellet quality still depends on upstream washing efficiency.
What is the expected maintenance for this densifier?
Routine maintenance focuses on the screw, barrel, screen cleaning, gearbox oil, and wear inspection. We provide a maintenance schedule and spare parts list with the machine.
What materials can the Plastic Film Densifier process?
PE film (LDPE/LLDPE), PP woven bags, raffia, stretch film, shrink film, agricultural film, and other washed flexible packaging materials.
Can it connect directly to a pelletizing extruder?
Yes. The densified, low-moisture granules feed consistently into plastic pelletizing lines, improving output and reducing pressure fluctuations.
What final moisture can I expect?
In most cases 1-3% with proper washing and drainage. We generally guarantee less than 5% to cover variation in input material and operation.
