Plastic Pellets, Flakes, and Regrind
Plastic Pellets · Resin Pellets · Plastic Flakes · Plastic Regrind · Polymer Granules
Plastic pellets, flakes, and regrind are forms of thermoplastic materials used in manufacturing and recycling processes. Pellets are typically uniform and free-flowing, while flakes and regrind can vary in size, shape, and bulk density. These materials are lightweight, sometimes electrostatically charged, and can become slippery or cohesive under certain conditions. KWS designs conveying systems that ensure reliable, low-dust, and contamination-free handling for plastic processing operations.

Material Characteristics
| Property | Value / Description |
|---|---|
| Common Forms | Pellets (Cylindrical or Spherical), Flakes (Irregular), Regrind (Shredded Fragments) |
| Bulk Density | 25–45 lb/ft³ (varies by polymer type and geometry) |
| Flow Behavior | Free-flowing for pellets; flakes and regrind may bridge or compact |
| Abrasiveness | Low generally non-abrasive to metal surfaces |
| Corrosiveness | Not Corrosive |
| Dust Potential | Moderate fines from regrind or flakes may become airborne |
Handling Challenges
- Bridging and inconsistent flow from irregular particle shapes
- Electrostatic charge causing sticking and dust adhesion
- Segregation of particle sizes during conveying and storage
- Pellet degradation or breakage from excessive mechanical handling
- Contamination risks in closed-loop or food-grade applications
Summary
Plastic pellets, flakes, and regrind require conveying and storage systems designed for gentle, clean, and efficient handling. KWS Manufacturing provides engineered solutions—including screw conveyors, drag conveyors, and bucket elevators—that maintain product integrity, minimize dust, and prevent contamination.
With decades of experience in plastics processing and recycling industries, KWS ensures reliable, efficient, and long-lasting performance for plastic material conveying systems.
