Soft Plastics Shredder Machine
Built for PE/PP films and soft plastics—bags, woven sacks, stretch film, agricultural film, big bags, and light textiles. As a reliable plastic film shredder for LDPE/LLDPE film shredding, it delivers stable feeding and anti-wrapping cutting for consistent size reduction before washing, densifying, or pelletizing.
Why Choose Our Soft Plastics Shredder?
Soft materials are prone to wrapping and bridging. Our design focuses on stable feeding, clean cutting, and dependable automation.
Anti-Wrapping Design
Knife arrangement and cutting chamber geometry are optimized to reduce film wrapping around the rotor and keep the machine running smoothly.
Stable Feeding for Light Materials
Designed to handle light, fluffy film and soft plastics with more consistent feeding and fewer stalls.
Controlled Output (Optional Screen)
Configure screen size to target downstream requirements—densifier input, washing line, or pelletizer feed.
PLC Control & Protection
PLC-based start/stop, forward/reverse, and overload protection improve safety and reduce operator workload.
Materials & Applications
A soft plastics shredder machine is commonly used before washing, squeezing/densifying, or pelletizing to reduce size and improve line stability.
Typical Materials
- LDPE/LLDPE film: stretch film, shrink film, agricultural film, packaging film
- PP woven bags, raffia, jumbo/big bags (FIBC), non-woven materials (a common PP woven bag shredder application)
- Soft plastic bags, liners, light flexible parts
- Industrial textiles and fibers (application dependent)
Downstream Processes
- Film washing lines (pre-cutting to improve washing efficiency)
- Film squeezer / densifier feed preparation
- Pelletizing lines (stable feeding and reduced bridging)
- RDF / SRF preparation (where applicable)
Working Principle & Key Components
Designed for soft plastics—stable feeding, clean shearing, and controlled discharge.
How Does a Soft Plastics Shredder Machine Work?
Material enters the hopper and is guided into the cutting chamber where rotor knives shear it against fixed counter-knives. Anti-wrapping design helps keep film from winding on the shaft. When a screen is installed, output size can be controlled before the material moves to the next step.
- Rotor & knives: Wear-resistant knives for reliable cutting on film and woven bags.
- Fixed counter-knives: Support consistent shearing and reduce entanglement.
- Screen (optional): Controls output size to match your washing/densifying process.
- PLC protection: Overload and reverse recovery logic for safer operation.

Proof: Build Quality, Safety & Serviceability
For industrial purchasing, details matter. Below are the checkpoints and options we can provide to support a reliable soft plastics shredder machine selection.
Manufacturing & QC Evidence
Process controls and inspection checkpoints that reduce risk.
- Bearing / gearbox options: Brand options available on request (per project and supply chain).
- Heat treatment: Knife and wear-part heat treatment matched to film/soft plastics and contamination level.
- Rotor dynamic balancing: Helps minimize vibration, noise, and bearing wear.
- Assembly tolerances: Critical-fit checks for shaft, coupling, and bearing seats.
- Pre-shipment testing (FAT): No-load + functional run, current draw, temperature rise, and control logic verification; test video available.
Safety & Protection
Designed to protect people and equipment in real-world recycling.
- Overload logic: PLC monitors load and triggers protection to avoid motor/drive damage.
- Reverse strategy: Auto reverse / recovery logic for bridging or stalled cutting (parameterized).
- E-stop & interlocks: Emergency stop + safety interlock readiness (e.g., access door/cover protection, depending on configuration).
- Metal contamination response: Support for upstream magnet separation; optional metal detection solutions can be discussed for high-risk streams.
Maintenance & Serviceability Details
Practical design choices that keep downtime low.
- Knife change method: Service-access design for faster knife rotation/replacement (final method depends on model).
- Knife steel options: D2 / SKD-11 options available based on wear expectation and budget.
- Screen change: Screen configuration and replacement method available for controlled output size.
- Lubrication points: Clear lubrication points and maintenance checklist support for routine servicing.
