Choosing the Right Plastic Film Densifier: A Practical, Technical Guide
Plastic film recycling has one stubborn bottleneck: flimsy, wet, low-bulk-density material that is difficult and expensive to handle. Densification—especially when paired with efficient dewatering—turns that bottleneck into a throughput boost. In this guide, Energycle Machine explains how densifiers and squeezer-densifier systems work, which KPIs matter, and how to select the right configuration for your line. The article is written for manufacturers, industrial recycling equipment buyers, and plant engineers across the USA and Europe who need technical depth and practical selection criteria. What a Plastic Film Densifier Does (and Why It Matters) In film recycling, you’re constantly fighting three disadvantages: extremely low bulk density (~20–50 kg/m³ for loose LDPE/LLDPE film), high moisture after washing, and inconsistent feeding into extruders or pelletizers. A plastic film densifier: Raises bulk density (often 3–6×), stabilizing material flow. Removes free and bound water...
