I. Efficiently Recycle LDPE Film into High-Quality Recycled Pellets

LDPE films and packaging bags are among the most widely used flexible packaging materials globally. They are commonly found in applications such as packaging films, shopping bags, industrial liners, agricultural films, and logistics packaging.

However, the efficient recycling of LDPE film faces many challenges due to its low bulk density, high moisture content, and tendency to tangle in feeding components. Recyclers frequently encounter issues such as unstable feeding, poor degassing performance, and inconsistent pellet quality.

To address these challenges, ACERETECH developed the ACSS double-stage compacting and pelletizing system—a high-efficiency recycling solution specifically designed for LDPE film and soft plastic waste. Integrating compacting, double-stage extrusion, vacuum degassing, and strands pelletizing process, the system ensures stable production, superior pellet quality, and continuous industrial-scale operation, with a capacity up to 1,000 kg/h.

II. Características del material y desafíos del reciclaje

Los residuos de films y bolsas de embalaje de LDPE suelen presentar los siguientes desafíos para el reciclaje:

*   Densidad aparente extremadamente baja y grandes requisitos de volumen de almacenamiento
*   Alto contenido de humedad tras el lavado
*   Presencia de contaminantes ligeros como polvo, etiquetas y restos de papel
*   Alimentación inestable causada por el enredo y la formación de puentes del material (atascos)
*   Altas exigencias en los procesos de filtración de masa fundida y desgasificación

Sin un sistema de reciclaje bien diseñado, estos desafíos pueden provocar fluctuaciones en la producción, mayores tiempos de inactividad, mala calidad de los gránulos y un aumento de los costes operativos.

2. Ventajas clave del sistema de granulación ACSS

🔹 High-Efficiency Cutter-Compactor for Stable Feeding

The system features a 2000-liter cutter-compactor chamber that integrates cutting, mixing, drying, and compacting functions.

Advantages include:

Rapid volume reduction of bulky film waste
Evaporation of surface moisture via frictional heating
Material homogenization prior to extrusion
Continuous, stable feeding to the extruder

This design effectively resolves common feeding challenges associated with soft plastic films.

🔹 Intelligent Conveying and Metal Protection System

Belt conveyor equipped with metal detector ensures safe and reliable operation.

Advantages include:

Automatic material conveying
Early detection of metal contaminants
Protection of screw and barrel components
Reduced risk of unplanned downtime

🔹 Two-Stage Single-Screw Extrusion for Superior Melt Quality

The ACSS system utilizes a two-stage extrusion design:

First-Stage Extruder

Screw diameter: Ø180 mm
Responsible for plasticization and primary filtration

Second-Stage Extruder

Screw diameter: Ø200 mm
Responsible for melt stabilization, homogenization, and fine filtration

Compared to traditional single-stage systems, two-stage extrusion significantly improves melt consistency and pellet quality, making it ideal for high-capacity film recycling applications.

🔹 Enhanced Vacuum Degassing

To enhance the quality of recycled pellets, the system incorporates:

Roots vacuum degassing system

This configuration effectively removes:

Moisture
Volatile compounds
Printing ink residues
Residual odor

This can achieve cleaner melt flow, reduce black spots, lower bubble content, and significantly improve downstream processing performance.

🔹 Stable Strand Pelletizing System

Processed through the strands pelletizing system:

Pellets with uniform size
Pellets with consistent shape
Excellent flowability
The recycled LDPE pellets are suitable for a wide range of secondary manufacturing applications.

FAQ

A: Los sistemas de granulación con compactador integrado son ampliamente reconocidos como una de las soluciones más eficaces para el reciclaje de film de LDPE, ya que mejoran la estabilidad de la alimentación, reducen el volumen del material y producen granza reciclada de alta calidad.

A: El film de LDPE tiene una densidad aparente muy baja y a menudo contiene humedad, polvo, etiquetas y residuos de impresión. Estas características hacen que los procesos de alimentación, desgasificación y filtración sean más complejos en comparación con los plásticos rígidos.

A: El proceso de extrusión en dos etapas ofrece una filtración del fundido superior, estabilidad de presión y homogeneización del material, lo que se traduce en una mayor calidad de la granza y un proceso de producción más estable.

A: Los gránulos de LDPE reciclado se utilizan habitualmente para fabricar bolsas de basura, películas para embalaje, películas agrícolas, láminas de plástico y diversos productos moldeados por inyección no destinados al contacto con alimentos.

A: Dependiendo de las condiciones del material y de la configuración del equipo, la capacidad de los sistemas industriales de granulación de películas de LDPE suele oscilar entre 300 kg/h y más de 1.500 kg/h. El sistema ACERETECH ACSS utilizado en este proyecto tiene una capacidad aproximada de 1.000 kg/h.
