ISHITVA® Flake Sorter
In plastic recycling, purity is profit. Even a few contaminated flakes can reduce batch value, impact quality, and increase rejections. That’s why visual inspection or random sampling is no longer enough.
Sort by Polymer. Sort by Color.
What is Ishitva’s Flake Sorter?
In plastic recycling, purity is profit. Even a few contaminated flakes can reduce batch value, impact quality, and increase rejections. That’s why visual inspection or random sampling is no longer enough.
The ISHITVA® Flake Sorter brings intelligence and automation to this critical stage. Powered by AI, machine learning, and hyperspectral vision, it doesn’t just sort—it understands. The system can detect polymers, colors, and contaminants invisible to the human eye, ensuring every flake that passes through your line contributes to higher yield and consistent quality.
From PET, HDPE, and PP to mixed regrinds, the Flake Sorter separates materials with precision—delivering a cleaner, purer output that meets buyer specifications every single time.
Why Ishitva’s Flake Sorter Matters
Manual or semi-automated flake sorting can’t keep up with the demands of food-grade, fiber-grade, or brand-grade recycling. The Flake Sorter revolutionizes this process with real-time, automated detection and data-backed sorting accuracy at industrial scale.
With it, you can:
- Sort flakes by polymer, color, and contamination
- Remove PVC, metals, and off-colored flakes instantly
- Achieve consistent batch purity
- Reduce manual dependency and sorting errors
- Meet food-grade and brand-grade compliance standards
- Improve yield and profitability through cleaner output
With Ishitva’s Flake Sorter, you don’t just clean your flakes—you redefine what “clean” means.
Key Capabilities
For PET Flakes
- Detects and separates unwanted polymers (HDPE, PP, PVC, PC, etc.)
- Identify and eject flakes with unwanted colors (Green, Brown, Black, Red, Orange, Yellow, degraded PET)
- Detects and separates metal fines coming from caps, closures, or neck rings
- Detects and separates BOPP PVC flakes coming from labels and sleeves
- Maintain <30 PPM contamination levels
- Enable high-purity bottle-to-bottle or food-grade rPET output
For HDPE & PP Regrinds
- Separate by polymer type, color, and even as per your MFI requirements.
- Detects and separates various polymer types, including PVC, PC, HIPS, ABS, and more.
- Identify and separates label residues, films, or colored contaminants
- Ensure consistent material quality for high-value upstream applications like caps, closures, pipes, and containers.

Pre-requisites for Flake Sorter
- Cleanliness
- The flakes must be washed and free from dust, labels, glue, and moisture.
- Presence of dirt, sticky residues, or wet flakes can affect optical and hyperspectral detection accuracy.
- Impurity Level
- The incoming material should have a manageable impurity level suitable for optical sorting (e.g., <5% contamination) for best throughput and purity results.
- Size Consistency
- Flake size should be uniform (typically 3–12 mm) to allow even feeding and consistent detection.
- Material Preparation
- Ensure flakes are properly dried before feeding.
- Avoid overlapping or agglomerated flakes on the conveyor or feeding system.
- Feeding & Flow
- Maintain a steady, uniform layer of flakes on the belt.
- Proper vibration feeding helps achieve stable sorting accuracy.
