The recycling of plastic films and bags presents unique challenges in material handling and processing. Specialized industrial equipment has been developed to address these challenges, combining robust engineering with intelligent design to optimize the recycling of flexible plastic packaging materials.
Processing thin plastic materials requires equipment that can handle:
Material tangling and wrapping
Variable thickness (0.01-0.2mm)
High contamination levels (up to 40% in post-consumer waste)
Electrostatic adhesion
Modern systems overcome these challenges through three key innovations:
Anti-Wrapping Rotor Design
Helical blade arrangement prevents material accumulation
Self-cleaning cutting edges maintain efficiency
360° rotating shafts eliminate dead zones
Advanced Separation Technology
Air classification systems (98% purity)
Electrostatic separators remove dust particles
Optical sorting for contaminant detection
Energy-Efficient Processing
Variable frequency drives reduce power spikes
Heat recovery from friction energy
Low-inertia rotor systems
