PE Film Pelletizing Machine

The PE film pelletizing machine we offer is designed for recycling common soft plastics such as HDPE, LDPE, LLDPE, PP, and PS.

It is ideal for processing both clean production scraps and post-washed materials.

Whether you're recycling clean film waste or handling contaminated materials like woven bags, agricultural film, or dirty post-consumer waste, we provide the right single-stage or two-stage pelletizing solutions to match your needs.

Our systems ensure that the final pellets meet high-quality standards, regardless of input complexity.

    Double Stage Pelletizing Machine Process

     

    Compactor Feeding Unit

    Pre-conditioning for Lightweight Film Scraps

    The compactor compresses lightweight film and edge trims into a denser, more uniform feed, enabling stable and continuous feeding into the extrusion screw.

    Key Features:

    High-speed shearing and frictional preheating

    Increases material bulk density for efficient extrusion

    Reduces bridging and feed fluctuations for improved system stability

    Screw Extrusion System

    Melting, Filtering, and Homogeneous Extrusion of Recycled Materials

    Performs melting, impurity filtration, and uniform extrusion of pre-treated plastic film materials.

    Key Features:

    Single-screw extruder design

    Optimized for high-contamination film feedstocks

    Forced Vacuum Degassing

    Ensures a smooth pellet surface with no black spots and no air bubbles, effectively improving the overall quality of the final product.

    Melt Filtration System

    Enables continuous production with non-stop screen changing, ensuring stable operation and consistent pellet quality.

    Optional Non-Stop Filter Types:

    Piston-type screen changer

    Plate-type screen changer

    Scraper-type (self-cleaning) filter

     

    		 

    Strand Pelletizing System

    Features a simple structure, low operational cost, and easy maintenance — ideal for general-purpose pelletizing applications.

    Optional Pelletizing Methods:

    Water ring pelletizing

    Underwater pelletizing

    Vibratory Screening System

    Removes fine impurities and oversize particles from finished pellets to ensure uniform size and high product purity.

    Final Product Collection System

    Collects finished pellets after cooling and screening, ensuring clean discharge, efficient packaging, and easy downstream handling.

     

     

     

    Pelletizing Strategies Based on Film Cleanliness Levels

    Different types of film waste require different pelletizing configurations to ensure optimal product quality and system performance. Below is a general guideline:

    Material Type

    Recommended Pelletizing Type

    Notes
    Washed PE film / Packaging film Single-stage or Two-stage pelletizer Depends on the required purity level of the final pellets. Two-stage is recommended for export-grade or high-end applications.
    PP woven bags (washed or unwashed) Two-stage pelletizer only Contains hard-to-remove impurities. Single-stage systems lack sufficient filtration, which may result in poor pellet quality and unstable downstream performance.
    Heavily contaminated film (e.g. agricultural film, mulch film, mixed post-consumer film) Two-stage pelletizer Often contains sand, oil, and heavy metal residues. Requires secondary filtration and stable extrusion to ensure pellets are odor-free and contaminant-free.
