EVA Film Pelletizing Machine

Product Overview

The EVA film pelletizing machine is a specialized device designed for the recycling and regeneration of waste plastic films. It features an advanced compacting and agglomeration feeding system, capable of directly processing whole rolls or bales of loose waste film without requiring prior shredding. The equipment employs an integrated process combining compaction and single-screw extrusion: first, the loose waste film is compacted and preheated; then, it undergoes melting and plasticization, impurity removal, and venting to eliminate moisture. Finally, it is transformed into high-quality recycled pellets. Standard models offer capacities ranging from 100 to 1500 kg/h, with finished pellets having a moisture content of ≤0.3% and filtration accuracy reaching 80–120 mesh, meeting the production needs of recycling facilities of various scales. Customization is available based on customer output requirements, making it suitable for diverse waste film recycling scenarios.

Technical Principle

The EVA film pelletizing machine utilizes an integrated core process of compaction and single-screw extrusion to efficiently convert loose waste film into high-quality recycled pellets. First, the waste film enters the compactor’s agglomeration hopper, where high-speed rotating blades cut and shred the material. Friction generated during rapid movement produces heat, naturally raising the temperature of the film. As the originally loose film heats up, it contracts and compacts into uniform agglomerates, increasing its bulk density by 3–5 times and ensuring stable feeding without bridging. Subsequently, the compacted agglomerates are smoothly fed into the extrusion screw. Through staged heating and shear action of the screw, the material achieves thorough melting and plasticization. Multi-stage screens then filter out impurities, while the exhaust system effectively removes moisture and volatile substances. Finally, water cooling and pelletizing produce uniformly shaped, bubble-free, high-quality recycled pellets.

Core Advantages

1. Stable feeding with no bridging: The compactor’s agglomeration feeding system compresses loose film into high-density pellets before feeding, completely resolving issues of air gaps, slippage, and uneven feeding found in conventional equipment, thus ensuring continuous and stable production.
2. Self-friction preheating for energy efficiency: High-speed friction within the compactor naturally raises the temperature of the material, eliminating the need for additional preheating equipment. This not only enhances plasticization efficiency but also significantly reduces energy consumption—saving over 15% per ton processed.
3. Eliminates the need for preliminary shredding: Whole rolls or bales of waste film can be fed directly into the machine without prior shredding, reducing labor by 1–2 workers, cutting manpower costs and processing time, and boosting overall productivity.
4. Excellent venting and dehumidification: Equipped with a comprehensive venting and dehumidification system, the machine effectively removes moisture from the material, resulting in finished pellets with moisture content ≤0.3%, bubble-free appearance, and a defect rate kept below 3%.
5. Reliable quality of core components: The screw and barrel are made of nitrogen-treated 38CrMoAlA alloy or bimetallic materials, while motors, bearings, and inverters all use top international or premium domestic brands, ensuring robust durability and stable operation.

Core Value of the Product

1. Simplified processes reduce costs and boost efficiency: By eliminating separate shredding steps and minimizing manual input, production time and labor costs are lowered, enabling up to 36 tons per day under 24-hour operation, dramatically increasing capacity.
2. Energy savings enhance profitability: The self-friction preheating design saves over 15% electricity per ton processed, yielding substantial long-term energy cost reductions. Additionally, production scraps can be fully recycled, further lowering raw material losses.
3. High-quality pellets secure market access: With low moisture content, bubble-free surfaces, and uniform appearance, the product meets downstream plastic manufacturers’ raw material standards, helping recycling companies expand stable sales channels.
4. Customizable solutions meet diverse needs: Available in capacities ranging from 100 to 1500 kg/h, the machine can be tailored to suit different production scales, adapting to various recycling scenarios.

Target Customer Groups

Plastic film producers, waste plastic recycling plants, packaging material companies, and resource recovery firms—especially those handling large volumes of agricultural greenhouse film, packaging stretch wrap, industrial films, and courier plastic bags. Whether small-scale recycling operations or large resource recovery groups, customers can select models that best match their specific capacity requirements.

Application Scenarios

This equipment is suitable for recycling and regenerating various types of waste plastic films, including post-season collection of agricultural greenhouse film, recycling of packaging stretch-wrap scraps, reuse of BOPP/CPP industrial films, resource recovery of discarded courier plastic bags, and pelletizing of heat-shrink films and other plastic waste. Regardless of whether the material is stored in whole rolls or collected in scattered pieces, it can be fed directly into the machine without additional preprocessing, adapting to diverse real-world conditions in waste film recycling.

Solutions to Industry Pain Points

1. Solves the challenge of feeding loose film: Traditional pelletizing machines often suffer from air gaps, slippage, and uneven feeding when processing loose film. The compactor’s agglomeration system increases bulk density by 3–5 times, ensuring continuous, stable feeding and preventing production interruptions.
2. Eliminates extra costs associated with preliminary shredding: Conventional waste film pelletizing requires prior shredding, adding both equipment expenses and labor. This machine handles whole rolls and bales directly, removing the need for shredding and reducing labor by 1–2 workers, thereby cutting both manpower and equipment costs.
3. Improves inadequate plasticization and low capacity: The compactor’s self-friction preheating prepares the material for extrusion, allowing more thorough plasticization once it enters the screw. Combined with a large-diameter screw and efficient shear structure, capacity is greatly enhanced—standard models reach up to 1500 kg/h, producing 36 tons daily under 24-hour operation.
4. Addresses high defect rates in wet-material pellets: The machine’s multi-stage venting system effectively removes moisture, resulting in finished pellets with moisture content ≤0.3%, bubble-free appearance, and a defect rate kept below 3%, enhancing product quality and market competitiveness.
