To address this specific challenge, HuaZhao has recently delivered a custom-tailored “Crusher / Side Feeder” PP PE Film Pelletizing Line for a client in Japan. This innovative modular system allows the client to handle diverse forms of PE film efficiently using a single production line.
Specifications of PE PP Film Pelletizing Line
Client Location: Japan
Machine Name: “Crusher / Side Feeder” PP PE Film Recycling Pelletizing Line (Water-Ring Cutting)
Model: HZ-160F
Processing Materials:
Crusher Mode: Unshredded dry PE films (raw material bags, courier bags, edge-trim rolls, etc.)
Side Feeder Mode: PP, PE film crushed flakes, washed film pieces, and powders
Production Capacity: 500–700 Kg/h (depending on material morphology and density)
Core Feature: One machine with dual purposes, flexible switching, solving feeding bottlenecks for dry films and low-density crushed materials.
System Workflow and Dual-Mode Operation
The entire pe pp pelletizing line consists of a belt conveyor, a dual-purpose inlet (interchangeable crusher barrel or side feeder), an extruder, a water-ring cutting system, a vibrating screen, and a storage silo.
Recycled from PE Powder
Recycled from PE Raw Materials
Mode 1: Crusher Barrel Mode (For Dry Film Materials)
Applicable Materials: Whole rolls of material bags, unbroken courier bags, and edge-trim film rolls.
Workflow: Materials are evenly fed into the integrated heavy-duty crusher via a conveyor belt. High-speed rotating blades inside the sealed barrel instantly shred large films into uniform small pieces through friction and shearing. Frictional heat naturally forms high-temperature thermal agglomerates, which are then directly compacted and fed into the extruder screw inlet.
Core Advantage: Direct feeding of thermal agglomerates ensures higher plasticization efficiency, achieving a seamless continuous process of “feeding-shredding-extrusion”.
Mode 2: Side Feeder Mode (For Crushed Materials / Powders)
Applicable Materials: Pre-processed film scraps, flakes, or powdery materials.
Workflow: When processing these materials, the operator switches to the side feeder module, which connects directly to the main extruder inlet. Materials enter the side feeder and are forcefully, uniformly, and controllably pushed into the main screw by a specialized twin-screw or single-screw mechanism.
Core Advantage: The forced-feeding design ensures stable, uniform, and controllable material transportation, guaranteeing high-yield and consistent extrusion.

Conclusion
By adopting a modular frontend switching design, HuaZhao’s dual-purpose PP, PE film recycling pelletizing machine allows users to effortlessly process both dry films and crushed materials using just one system.
The direct benefits for recycling plants include minimized initial investment by eliminating the need for duplicate production lines, maximized equipment utilization, and stable high-capacity outputs. It is the ultimate cost-effective solution for modern plastic recycling businesses looking to stay flexible in a complex market.
Frequently Asked Questions (FAQ) for B2B Buyers
Q: What is PP PE film pelletizing line?
A:
A PP/PE film pelletizing line (often called a plastic film recycling and granulating machine) is a specialized industrial production system designed to recycle waste plastic films—specifically Polypropylene (PP) and Polyethylene (LDPE, HDPE, LLDPE)—and convert them into reusable, high-quality plastic pellets (granules).
Because waste films (like shopping bags, agricultural films, stretch wrap, and packaging materials) are typically lightweight, bulky, and often contaminated or moist, standard recycling machines struggle to process them efficiently. A dedicated film pelletizing line is engineered to solve these unique challenges.
Q: How long does it take to switch between the crusher barrel mode and the side feeder mode?
A:
The system is designed with a modular quick-change structure. Typically, an experienced operator can complete the switch between the crusher barrel and the side feeder within 30 to 45 minutes, minimizing production downtime and maximizing operational flexibility.
Q: Can this dual-purpose machine handle wet film materials in the side feeder mode?
A:
Yes, but with conditions. The side feeder mode is optimized for pre-processed, crushed, and washed film flakes. However, if the moisture content of the washed flakes is relatively high, we recommend pairing the line with a proper dewatering or drying system beforehand to ensure stable extrusion and avoid bubbling in the final pellets.
Q: Does the dual-purpose configuration sacrifice the production capacity compared to a dedicated single-purpose machine?
A:
No. The HZ-600F model maintains a stable output of 500–700 Kg/h in both modes. HuaZhao’s precision-engineered screw design and forced-feeding mechanism ensure that plasticization and throughput remain consistently high regardless of whether you are processing dry film rolls or crushed flakes.
Q: What kind of maintenance is required for the heavy-duty crusher barrel?
A:
The crusher blades are made of high-wear-resistant alloy steel to extend their lifespan. We recommend daily routine checks for blade sharpness and clearance. Thanks to the open-access modular design, blade inspection and replacement are straightforward and require minimal labor time.
Q: Is this custom recycling line suitable for materials other than PE?
A:
While this specific model is optimized for PE (LDPE, HDPE, LLDPE) films, HuaZhao’s engineering team can customize the screw configuration, heating zones, and cutter systems to process other polymers such as PP, ABS, or PS based on your specific recycling requirements.
