Clean CPP/BOPP Pastic Film Recycling Line

Process A: CPP/BOPP Film Waste → Belt Conveyor → Metal Detector → Film Compactor → Extruder with Vacuum Degassing → Hydraulic Screen Changer → Pelletizing System → Pellet Cooling and Drying → Storage Hopper → Recycled Granules

Suitable for: Stable raw material supply, low impurity content, no washing required, and product quality requirements compatible with single-stage systems.

Advantages: Relatively simple equipment configuration, with the potential for lower investment, footprint, and maintenance costs.

Moderately Contaminated CPP/BOPP Plastic Film Recycling Line

Process B: CPP/BOPP Plastic Film Waste → Belt Conveyor → Metal Detector → Film Compactor → Primary Extruder → Hydraulic Screen Changer → Secondary Extruder → Hydraulic Screen Changer → Pelletizing System → Centrifugal Dewatering Machine → Pellet Storage Hopper → Recycled Granules

Suitable for: CPP/BOPP film production plants, flexible plastic packaging manufacturers, PP film waste recycling companies, and plastic recycling plants requiring stable feeding, two-stage filtration, and continuous pelletizing.

Advantages: Stable feeding; two-stage filtration ensures low impurity levels in the final product; efficient vacuum degassing in the two-stage extrusion process; stable, continuous production; and a wider range of applications for recycled PP pellets.

Key Considerations for Selecting a Plastic Film Recycling

Basic Selection Factors: Raw material type, target production capacity, intended use of recycled pellets, project budget

Target Production Capacity for the Entire Line	CPP/BOPP Raw Material Types	Applications of Recycled Pellets	Equipment Configuration and Positioning
100–200 kg/h	Clean production scrap	Standard Recycled PP Pellets	Economy
200–300 kg/h	Printed packaging film	High-Quality Recycled PP Pellets	Standard Export Configuration
300–500 kg/h	Post-consumer waste packaging film	Modified or Injection-Molding Grade Pellets	High-Automation Configuration
500–800 kg/h	Mixed or laminated packaging film
800–1,000 kg/h

Does CPP/BOPP film require washing?

Not necessarily. Clean production trimmings, clean printed film, or industrial waste film with a clearly identified composition can be directly compacted and extruded. Material containing food residues, grease, silt, or other contaminants requires sorting, washing, and drying. For PP/PE, PP/PET, or aluminum-foil-laminated films, standard filtration and two-stage extrusion cannot thoroughly separate the different polymers; separate pretreatment is required.

Are Two Hydraulic Screen Changers Necessary?

If the raw material is clean and contains few impurities, they are not necessary.

Is Two-Stage Extrusion Always Better Than Single-Stage Extrusion?

The choice between single-stage and two-stage extrusion should be based on a comprehensive evaluation that considers the level of raw material contamination and target production capacity, compares the total costs of single-stage vented extrusion, single-stage forced filtration, and two-stage extrusion, assesses the actual benefits of two-stage extrusion and two-stage filtration, and takes operating costs into account.

Selecting a Pelletizing System

Types of Granulation Systems	Applications
Water-Ring Pelletizing	General-purpose film recycling and pelletizing
Strand Pelletizing	Low investment, clean and stable raw materials
Underwater Pelletizing	High production capacity or high pellet consistency requirements
Air-Cooled Die-Face Pelletizing	Applications with water restrictions
