Plastic Film Squeezer Granulating Machine

The SUHUI plastic film squeezer granulating machine is a high-efficiency system designed to recycle plastic film waste directly into reusable granules. It processes materials including LDPE, HDPE, and PP films from packaging, agricultural covers, and industrial scraps — including wet or lightly contaminated films straight from the washing line.

By integrating crushing, squeezing, melting, and pelletizing into a single compact unit, this machine eliminates the need for a separate drying stage. The squeezing screw mechanically removes moisture and air from the film before it enters the extruder, significantly reducing energy consumption while producing dense, uniform granules.

Output pellets are suitable for extrusion, injection molding, and blow molding applications. The machine is widely used in plastic recycling facilities, film manufacturers, and waste management operations seeking a reliable, cost-effective pelletizing solution.

Key Features of SUHUI Plastic Film Squeezer

• Integrated Squeezing & Pelletizing: Combines moisture removal, melting, and granulating in one machine — no separate dryer required.
• High Throughput: Processes 300–750 kg/h depending on model, suitable for small to large recycling operations.
• Handles Wet Film Directly: Processes post-washing wet PP/PE film without pre-drying, reducing operating costs.
• Durable Hardened Steel Components: Wear-resistant screw and barrel ensure long service life with contaminated or abrasive materials.
• Energy-Efficient Design: Optimized heating zones and inverter-controlled motors minimize power consumption per kilogram of output.
• PLC Touchscreen Control: Real-time monitoring and adjustment of temperature, speed, and output parameters.
• Low Noise & Emissions: CE and ISO compliant design meets international environmental and safety standards.
• Easy Maintenance: Modular construction simplifies component access, cleaning, and part replacement.

Technical Data

How the Plastic Film Squeezer Granulating Machine Works

1. Film Feeding: Wet or dry PP/PE film scraps are fed into the machine via a conveyor belt or manual loading.
2. Crushing: A built-in crusher shreds bulky film rolls or bales into smaller pieces for consistent feeding.
3. Squeezing & Dewatering: The high-torque squeezing screw compacts the film and mechanically expels moisture before the material enters the heating zone.
4. Melting & Extrusion: The compacted, dried material is heated and melted in the extruder barrel, then forced through the die head.
5. Granulating: A rotating cutter slices the extruded melt into uniform pellets at the die face.
6. Cooling & Conveying: Pellets are air-cooled and conveyed to a storage silo or directly to packaging.

Frequently Asked Questions

What plastic film materials can the SUHUI squeezer granulating machine process?

The machine processes LDPE, HDPE, and PP plastic films including post-consumer packaging film, agricultural mulch covers, stretch wrap, and industrial film scraps. It accepts both wet film directly from the washing line and dry film without requiring pre-drying, making it suitable for integration into washing and recycling production lines.

Does the squeezer granulating machine require a separate dryer?

No. The integrated squeezing screw mechanically removes moisture and air from the film before it enters the heating zone, eliminating the need for a separate thermal drying stage. This reduces energy consumption and simplifies the production line layout while allowing wet film to be processed directly after washing.

What output capacity does the machine deliver?

The SUHUI plastic film squeezer granulating machine is available in three models: SH300 (300–500 kg/h), SH320 (400–550 kg/h), and SH350 (600–750 kg/h). Model selection depends on feedstock volume, film type, and moisture content. SUHUI engineers can recommend the appropriate model based on your specific production requirements.

What size pellets does the machine produce?

The machine produces pellets with a diameter of 12 mm or larger, cut by a rotating die-face cutter at 400 rpm. Pellet size can be adjusted by modifying the cutter configuration. Output pellets are suitable for use in extrusion, injection molding, and blow molding manufacturing processes.

What contamination level can the machine handle in input film?

The machine is designed for wet or lightly contaminated film scraps typical of post-washing recycling operations. The hardened, wear-resistant squeezing screw and barrel components extend service life when processing mildly abrasive or contaminated materials. For heavily contaminated film, a multi-stage washing line upstream is recommended to improve output pellet quality.

What are the power requirements for the different squeezer granulating machine models?

The SH300 model uses a 90 kW main motor and a 4 kW granulating motor. The SH320 model uses a 132 kW main motor and a 5.5 kW granulating motor. The SH350 model uses a 160 kW main motor and a 7.5 kW granulating motor. All models include an inverter-controlled drive system for energy-efficient operation and adjustable output speed.
