What Materials Can Be Processed?

A plastic film pelletizing machine is suitable for:

PP film scrap
PE packaging film
LDPE agricultural film
Stretch film
Shopping bags
Woven bags (after crushing)
Post-consumer washed film

Material cleanliness and moisture level will directly affect machine configuration.

Why Film Pelletizing Requires Specialized Design

Unlike rigid plastics, film materials have:

Low bulk density
High flexibility
Easy screw wrapping
Possible sand or ink contamination

Therefore, a dedicated film pelletizing system must include:

✔ Compactor feeding system
✔ Optimized screw structure
✔ Vacuum degassing
✔ Efficient melt filtration
✔ Stable pellet cutting unit

Main Technical Specifications

Equipment Parameters

Parameter	Typical Range
Screw Diameter	85 – 160 mm
L/D Ratio	30:1 – 36:1
Output Capacity	200 – 1200 kg/h
Motor Power	55 – 200 kW
Pellet Size	3 – 4 mm
Filtration Precision	80 – 200 mesh
Pellet Moisture	≤ 1%
Control System	PLC automatic control

Actual configuration depends on raw material condition and required output.

Water Ring vs Strand Pelletizing

For PP PE LDPE film recycling:

Water ring pelletizing – high efficiency, automatic operation, widely used for film materials
Strand pelletizing – simpler structure, suitable for rigid plastics

Water ring systems are generally preferred for film processing due to higher productivity and automation.

Energy Consumption & Operating Efficiency

Typical energy consumption:
280 – 450 kWh per ton

Factors affecting energy efficiency:

Material moisture
Screw design
Temperature control accuracy
Motor quality

Optimized systems reduce long-term electricity costs and improve profitability.

Single Stage vs Double Stage Film Pelletizing

Stage Comparison

Item	Single Stage	Double Stage
Suitable Material	Clean industrial film	Post-consumer film
Filtration Efficiency	Medium	High
Pellet Stability	Good	Excellent
Investment Cost	Lower	Higher

For agricultural or heavily contaminated films, double-stage extrusion is recommended to improve pellet quality.

Frequently Asked Questions

What is the delivery time and payment terms?

Yes. The integrated model is equipped with an enhanced cleaning module (bubble cleaning + high-pressure spray), which can effectively remove soil and oil stains on the film surface; the subsequent centrifugal dehydrator can dehydrate the film to moisture content ≤1%, ensuring the melting effect. For severely polluted materials, an additional chemical cleaning module can be customized.

Can PP, PE and LDPE film materials be processed at the same time?

Yes. The twin-screw model is specially designed for mixed materials; it has strong mixing and melting capacity, which can uniformly mix and melt PP, PE and LDPE film materials. It is recommended to pre-classify the materials if high-purity single-material pellets are required, and the single-screw model can be used for separate processing.

What is the daily maintenance requirement of the equipment?

Daily maintenance mainly includes: 1) Clean the crusher, cleaning tank and filter screen regularly to avoid impurity accumulation; 2) Check the wear of the crusher blade and pelletizing cutter, and replace them in time when the wear is excessive; 3) Lubricate the transmission parts (bearing, gearbox) regularly; 4) Check the heating system and sensors to ensure accurate temperature control and parameter monitoring.

Do you provide sample testing services?

Yes. Customers can send their PP/PE/LDPE film waste samples to us; we will process them into finished pellets using the corresponding model equipment and send the samples back for inspection. We also provide test reports (pellet purity, moisture content, particle size) to help customers confirm the equipment performance. The courier cost is borne by the customer.
