PE Film Granulator

Product Overview

The PE film granulator is a customized, dedicated equipment for recycling and granulating plastic films, launched by the PURUI brand and manufactured in Nantong. It features an exclusive densifier–pelletizing feeding system that can directly compact and preheat fluffy waste plastic films, efficiently converting them into high-quality recycled pellets without the need for prior shredding, thus greatly simplifying the production process. The machine employs an integrated densifier–single-screw extrusion process, enabling it to handle entire rolls or bundles of film directly, increasing material bulk density by 3–5 times, ensuring more uniform and stable feeding, and producing finished pellets with a moisture content ≤0.3% and excellent appearance free of air bubbles. This equipment supports customized production to meet various output requirements and is suitable for diverse waste film recycling scenarios.

Technical Principle

This equipment utilizes an integrated densifier–single-screw extrusion process to achieve efficient recycling and granulation of waste films. First, the waste film enters the densifier (pelletizing hopper), where high-speed rotating blades cut and crush the material. Friction generated during rapid movement produces heat, causing self-heating; the originally fluffy film contracts and compacts into uniform pellets, significantly increasing bulk density before being fed steadily into the extrusion screw. Subsequently, the material undergoes staged heating and screw shearing to complete melting and plasticization, followed by multi-stage filtration and venting to remove impurities and moisture. Finally, after water-cooling and shaping, the material is cut into pellets, yielding high-quality PE recycled granules. The entire process eliminates the need for preliminary shredding, relying instead on self-frictional preheating, which both enhances plasticization efficiency and saves energy.

Core Advantages

1. Stable feeding without bridging: Equipped with a densifier–pelletizing feeding system, the machine compacts fluffy films into uniform pellets before feeding them into the screw, completely resolving issues of feed blockage, slippage, and uneven feeding common in traditional granulators, ensuring continuous and stable production.
2. Self-frictional preheating for greater energy efficiency: The material self-heats through high-speed friction within the densifier, eliminating the need for additional preheating equipment, improving plasticization efficiency, and saving over 15% electricity per ton processed, significantly reducing production energy costs.
3. Elimination of shredding step: The machine can directly process whole rolls or bundles of film without prior shredding, reducing labor by 1–2 workers, lowering labor costs and operational complexity, and boosting production efficiency.
4. Excellent venting and dehumidification: After multiple stages of venting and dehumidification, the finished pellets maintain a moisture content ≤0.3%, exhibit excellent appearance free of air bubbles, and keep the defect rate below 3%, ensuring stable and reliable product quality.
5. Customizable adaptation: Supports tailoring to customer-specific output needs, covering a capacity range of 100–1500 kg/h, and accommodating varying scales of waste film recycling operations.

Core Product Value

1. Simplified production workflow: By eliminating the separate shredding step, reducing labor input, and cutting down on time and manpower required at each stage, overall production efficiency is enhanced.
2. Energy savings and reduced consumption: Self-frictional preheating and plasticization save over 15% electricity per ton processed, significantly lowering long-term electricity expenses and boosting corporate profitability.
3. High-quality output: Finished pellets feature low moisture content, no air bubbles, and a defect rate ≤3%; production scraps can be fully recycled, improving raw material utilization and enhancing market competitiveness.
4. Flexible and controllable capacity: Offers customizable production options, with a maximum daily output of up to 36 tons under 24-hour operation, flexibly meeting diverse customer demand and adapting to various production scales.

Plastic film manufacturers, waste plastic recycling plants, packaging material companies, and resource regeneration firms—all these enterprises generate substantial quantities of waste plastic films requiring recycling. The equipment’s high efficiency and energy-saving features effectively address their production needs, enhancing the value of recovered resources.

Application Scenarios

This equipment is suitable for recycling and regenerating various types of PE waste films, including agricultural greenhouse films, packaging stretch films, BOPP/CPP industrial films, courier plastic bags, heat-shrink films, and more. Whether operating large-scale waste plastic recycling facilities or small packaging material companies handling edge scrap, this machine can transform fluffy waste films into high-quality recycled pellets, realizing circular resource utilization.

Solutions to Industry Pain Points

1. Addressing issues of feed blockage and uneven feeding caused by fluffy films: The densifier–pelletizing feeding system compacts fluffy films into uniform pellets, ensuring smooth and continuous feeding and preventing production interruptions.
2. Eliminating extra costs associated with pre-shredding: No need to separately equip shredding machinery or hire workers; direct processing of whole rolls or bundles reduces procedural steps and labor input, lowering production costs.
3. Improving inadequate plasticization and low capacity: After self-frictional preheating, the material enters the screw, dramatically boosting plasticization efficiency; standard models achieve capacities of 100–1500 kg/h, with a maximum daily output of 36 tons under 24-hour operation, effectively expanding production scale.
4. Solving problems of excessive air bubbles and high defect rates in wet-material granulation: Multi-stage venting and dehumidification ensure finished pellets have a moisture content ≤0.3%, exhibit excellent appearance free of air bubbles, and keep the defect rate below 3%, thereby improving product pass rates and quality.
