I. Efficient PA6 film recycling begins with reliable size reduction
As the demand for engineering plastic recycling grows, the volume of PA6 (polyamide 6/nylon 6) film recovered from packaging, industrial production, and processing operations is steadily increasing.
However, the characteristics of PA6 film—such as extreme thinness, high toughness, and continuous roll form—present unique challenges for the recycling process. Conventional shredding equipment often struggles to handle this material, frequently encountering issues like material wrapping, unstable feeding, low throughput, and excessive downtime.
To address these challenges, ACERETECH has developed a customized PA6 film crushing solution based on the GH heavy-duty crusher. This solution ensures stable feeding and efficient size reduction, providing a reliable foundation for subsequent washing or pelletizing processes.
II. Project Overview
Material Information
The material processed in this project consists of ultra-thin PA6 film rolls, measuring just 10 microns in thickness and 1000 millimeters in width. Given the film's high flexibility and tendency to tangle, achieving efficient feeding and crushing is critical to overall recycling performance.

IV. Challenges in PA6 Film Crushing
Recycling and processing PA6 film differs significantly from processing rigid plastics such as HDPE, PP, or PET.
1. Ultra-thin film structure
PA6 film is only 10 μm thick; if feeding is not properly controlled, the film is highly prone to folding, stretching, or wrapping around the rotor.
2. High tensile strength
Nylon film possesses excellent mechanical properties and toughness, placing higher demands on the equipment's cutting performance and rotor design.
3. Continuous roll feeding
Wide film rolls often lead to unstable feeding, easily causing bridging or material accumulation issues.
4. Uniform particle size requirements
Downstream washing lines and pelletizing systems require uniform crushed flake sizes to ensure processing stability and melt quality.
V. ACERETECH PA6 Film Crushing Solution
1. Dual-traction feeding system
The dual-traction unit continuously pulls the film into the crushing chamber at a controlled speed. Advantages include:
Stable material feeding
Prevention of film accumulation
Reduced manual intervention
Increased production efficiency
2. Heavy-duty rotor design
The GH series shredder features a large-diameter (700mm) rotor with the following characteristics:
High cutting efficiency
Stable rotational inertia
Low energy consumption
Long blade service life
3. Hydraulic ram assistance
The hydraulic ram ensures consistent contact between the material and the rotor, maximizing shredding efficiency while maintaining a stable output.

FAQ
Q1. Can PA6 film be recycled into high-value engineering plastic pellets?
A: Yes. After crushing, washing, drying, and pelletizing, recycled PA6 film can be converted into high-quality nylon pellets suitable for various applications, including automotive components, industrial parts, packaging products, and engineering plastic compounds. The quality of the final pellets depends on material purity, moisture control, and the pelletizing process.
Q2. Why is a large rotor diameter important for crushing PA6 film?
A: A larger rotor diameter provides higher cutting inertia and more stable operation when processing tough engineering plastics such as PA6. The 700 mm rotor used in the GH crusher improves cutting efficiency, reduces energy consumption, minimizes vibration, and helps prevent film wrapping around the rotor during continuous operation.
Q3. What feeding system is recommended for wide-width film rolls?
A: For wide-width film rolls such as 1000 mm PA6 film, a dual traction feeding system is highly recommended. Compared with manual feeding or conveyor feeding, dual traction devices ensure stable material tension and continuous feeding speed, significantly reducing downtime caused by film accumulation or blockage.
Q4. Can the GH crusher be integrated into a complete PA6 recycling line?
A: Yes. The GH crusher can be integrated with downstream washing, drying, extrusion, and pelletizing systems to form a complete PA6 film recycling line. ACERETECH can provide customized turnkey recycling solutions based on material condition, contamination level, and required production capacity.
Q5. How can recyclers improve the efficiency of PA6 film recycling?
A: To maximize recycling efficiency, recyclers should focus on:
Stable and continuous feeding
Proper crushing particle size
Effective drying and moisture control
High-performance melt filtration
Optimized extrusion and pelletizing technology
A well-designed recycling system can improve production efficiency, reduce operating costs, and increase the value of recycled PA6 materials.
