PVC Soft Film Recycling Pelletizing Machine

Product Overview

The PVC soft film recycling pelletizing machine is a specialized equipment for regenerating and pelletizing films, equipped with a densifier–pellet feeding system. It is a customized product without a fixed price, tailored according to the customer’s production requirements. The machine can directly process whole rolls or bundles of fluffy waste film without prior shredding. Through the densifier’s preheating and compaction process, it efficiently converts the material into high-quality recycled pellets with a moisture content ≤0.3% and excellent appearance. Standard models offer capacities ranging from 100 to 1500 kg/h, meeting the recycling needs of various types of used PVC soft films, making it a core piece of equipment for plastic recycling and processing enterprises.

Technical Principle

This pelletizer employs an integrated process combining a densifier and a single-screw extruder, enabling complete conversion from waste film to recycled pellets. First, the waste film enters the densifier (pelletizing hopper), where high-speed rotating blades cut and shred the material. Frictional heat generated during this process raises the temperature of the material, causing the originally fluffy film to shrink and compact into uniform pellets, increasing its bulk density by 3–5 times. The pellets are then fed steadily into the extrusion screw. In the extrusion stage, the material undergoes staged heating and shear action by the screw to achieve melting and plasticization. It then passes through multi-stage filters with mesh sizes of 80–120 to remove impurities while simultaneously venting air and moisture. Finally, after water cooling and shaping, the pellets are cut into granules, yielding high-quality recycled PVC soft film pellets.

Core Advantages

1. Densifier feed prevents bridging: With a densifier–pellet feeding system, the material’s bulk density is significantly increased before entering the screw, completely resolving issues of loose film feeding—such as bridging, slippage, and uneven feeding—ensuring consistent, stable feeding and enhancing production continuity.
2. Self-friction preheating saves energy: The material achieves self-heating within the densifier through high-speed friction, eliminating the need for additional preheating equipment. This not only improves plasticization efficiency but also effectively reduces energy consumption, saving more than 15% per ton processed and substantially lowering production costs.
3. Eliminates shredding step: Whole rolls or bundles of waste film can be fed directly into the machine without prior shredding, reducing the need for 1–2 operators, cutting labor costs and simplifying processes, thereby boosting production efficiency.
4. Excellent venting and dehumidification: Multi-stage venting and dehumidification effectively removes moisture and impurities from the material, resulting in finished pellets with moisture content ≤0.3%, bubble-free appearance, and a defect rate kept below 3%, ensuring high-quality recycled pellets.
5. Wide capacity range: Standard models offer capacities from 100 kg/h to 1500 kg/h, with a maximum daily output of up to 36 tons when operating 24 hours a day, meeting the production needs of businesses of varying scales. Additionally, edge scraps can be fully recycled in a closed-loop system, maximizing resource utilization.

Core Value of the Product

1. Simplifies the production process by eliminating the shredding step, reducing labor input, and lowering both production and labor costs.
2. Self-friction preheating technology enhances plasticization efficiency, significantly cuts electricity consumption, and enables energy-efficient production.
3. Stable feeding and plasticization processes ensure high-quality recycled pellets with low defect rates, improving product market competitiveness.
4. A broad capacity range accommodates businesses of different sizes, while 100% recycling of edge scraps maximizes resource circulation.

Target Customer Groups

Plastic film manufacturers, waste plastic recycling plants, packaging material companies, and renewable resource firms—all these enterprises generate large quantities of used PVC soft films that require treatment. This equipment helps them efficiently recycle and regenerate waste materials into reusable plastic pellets, enhancing resource utilization and improving corporate economic performance.

Application Scenarios

This equipment is suitable for recycling and regenerating various types of PVC soft films, including agricultural greenhouse films, packaging stretch films, BOPP/CPP industrial films, courier plastic bags, heat-shrink films, and other waste films. Whether it’s whole rolls of industrial waste film or scattered courier plastic bags, they can all be directly fed into the machine for processing into high-quality recycled pellets, which can then be used to manufacture various plastic products, achieving resource circularity.

Solutions to Industry Pain Points

1. Addresses the pain point of loose film feeding—bridging, slippage, and uneven feeding—by using the densifier–pellet feeding system to compress fluffy material into high-density pellets, ensuring smooth, even feeding and preventing production interruptions or capacity fluctuations caused by feeding issues.
2. Solves the problem of needing to shred materials beforehand, adding extra steps and labor: The machine can handle whole rolls and bundles directly, eliminating the need for additional shredding, reducing 1–2 operators, simplifying the production process, and cutting labor and time costs.
3. Tackles the issue of insufficient plasticization and low productivity: The dual plasticization process of self-friction preheating combined with staged screw heating ensures thorough melting and plasticization, coupled with a stable feeding system, effectively boosting capacity to a maximum daily output of 36 tons.
4. Resolves the problem of wet material producing pellets with many bubbles and high defect rates: Multi-stage venting and dehumidification, paired with high-precision filtration, results in finished pellets with moisture content ≤0.3%, bubble-free appearance, and a defect rate controlled below 3%, guaranteeing stable product quality.
