Aluminum-Plastic Composite Film Granulator

Product Overview

The aluminum-plastic composite film granulator is a specialized machine designed for the recycling and regeneration of waste films. It features an advanced densifier–pelletizing feeding system, enabling it to process loose, bulk waste films directly—without requiring prior shredding. The equipment employs an integrated densifier–single-screw extrusion process, which compacts and preheats the fluffy waste film before efficiently converting it into high-quality recycled pellets. The finished pellets have a moisture content of ≤0.3% and an excellent appearance with no air bubbles, meeting the requirements of various recycled plastic processing applications. As a customized product, the machine can be configured according to customers’ production capacity needs; standard models offer capacities ranging from 100 to 1,500 kg/h, suitable for waste film recycling scenarios of different scales.

Technical Principle

This equipment utilizes an integrated core process combining a densifier and single-screw extrusion to achieve complete conversion of waste films into high-quality recycled pellets. First, the waste film enters the densifier (pelletizing hopper), where high-speed rotating blades cut and shred the material. During this rapid motion, intense friction generates heat, causing the fluffy film to contract and compact into uniform pellets, increasing its bulk density by 3–5 times. This effectively resolves the issue of feed bridging and slippage found in conventional machines, ensuring smooth feeding into the extrusion screw. In the extrusion stage, the material undergoes staged heating and shear action by the screw, achieving thorough melting and plasticization. It then passes through multi-stage filters with filtration precision up to 80–120 mesh to remove impurities, followed by venting and dehumidification to eliminate moisture and contaminants. Finally, water-cooling and pelletizing produce high-quality recycled pellets with a moisture content of ≤0.3%.

Core Advantages

1. Densifier feeding system: The unique densifier–pelletizing structure effectively addresses industry challenges such as feed bridging and uneven feeding caused by fluffy films, ensuring uniform and stable feeding and guaranteeing continuous, efficient operation.
2. Self-friction preheating and plasticization: The material achieves self-heating through high-speed friction within the densifier, resulting in higher plasticization efficiency when entering the extrusion screw. Compared to traditional equipment, this reduces energy consumption by over 15% per ton processed, making it more energy-efficient and environmentally friendly.
3. Eliminates pre-shredding step: The machine can handle whole rolls or bundles of waste film directly, without prior shredding, reducing labor by 1–2 workers, lowering labor costs and simplifying processes, thereby boosting overall production efficiency.
4. Efficient venting and dehumidification: An advanced venting and dehumidification system effectively removes moisture and volatile impurities, yielding finished pellets with ≤0.3% moisture, excellent appearance free of air bubbles, and a defect rate kept below 3%.
5. Flexible customization: As a customizable product, the machine’s parameters can be adjusted to meet specific production capacity needs, covering a range of 100–1,500 kg/h and adapting to recycling facilities of varying sizes.
6. High-quality component assurance: Core components are sourced from international first-tier brands or premium domestic suppliers, including motors from Siemens, ABB, and bearings from NSK, SKF, ensuring stable, reliable operation and extended service life.

Core Product Value

1. Cost reduction and efficiency gains: By eliminating the need for shredding and reducing labor input, combined with self-preheating and lower energy consumption, the machine saves over 15% on electricity per ton processed, while enabling up to 36 tons of daily output under 24-hour operation, significantly improving productivity and cutting operating costs.
2. Enhanced product quality: The finished pellets feature low moisture, no air bubbles, and excellent appearance, with a defect rate maintained below 3%. Scrap generated during production can be fully recycled, maximizing raw material utilization and creating greater value for customers.
3. Simplified production workflow: The machine handles entire rolls of waste film directly, bypassing the need for preliminary shredding, streamlining processes, reducing operator workload, and minimizing equipment and space requirements.
4. Versatile material compatibility: Capable of processing agricultural greenhouse films, packaging stretch films, BOPP/CPP industrial films, courier plastic bags, shrink wrap, and other types of aluminum-plastic composite waste, offering broad applicability to meet diverse waste film recycling needs.

Target Customer Groups

This equipment is primarily aimed at plastic film manufacturers, waste plastic recycling plants, packaging material companies, and resource recovery enterprises—especially those with large-scale waste film recycling needs. Whether small-to-medium-sized recycling facilities or large resource recovery groups, they can customize equipment models tailored to their specific production capacity requirements.

Application Scenarios

The aluminum-plastic composite film granulator is suitable for various recycling and regeneration scenarios involving used aluminum-plastic composite films, including post-season recycling of agricultural greenhouse films, recovery of stretch films and BOPP/CPP industrial film waste from the packaging industry, collection of vast quantities of plastic bags from the courier sector, as well as regeneration processing of shrink wrap and other industrial waste films. By transforming these used films into high-quality recycled pellets, they can be reused to manufacture new plastic films, containers, pipes, and other plastic products, achieving resource circularity that aligns with environmental policies while delivering significant economic benefits to businesses.
