In the industrial recycling sector, operational efficiency is defined by two critical metrics: moisture control and volume reduction. For facilities handling bulky waste like PP/PE films or woven bags, high-performance Plastic Film Squeezing & Densifying technology is the most effective way to cut logistics costs and prepare material for high-quality pelletizing.
Understanding the relationship between compressed density and compression ratio allows recyclers to optimize their complete plastic recycling solutions for maximum throughput and profitability.

Technical Insights: How Density Impacts Your Process
A highly efficient plastic film squeezer and densifier works by applying massive mechanical torque to wet plastic scrap. This process doesn’t just remove water—it uses frictional heat to transform loose flakes into dense, semi-molten granules.
The Loose Material Challenge
Post-consumer film typically has a bulk density as low as 0.02 g/cm³. This makes transportation prohibitively expensive and causes “bridging” or inconsistent feeding in most recycling extruders.
The Rumtoo Densified Solution
By utilizing our heavy-duty PP/PE film squeezer machine, you achieve a material density of 0.90-0.97 g/cm³. This near-intrinsic density ensures a stable, high-speed feed into your pelletizing line.
Reference Table: Density by Polymer Type
| Material Type | Target Density (g/cm³) | Common Form Factor |
|---|---|---|
| LDPE | 0.91 – 0.94 | Dense “Popcorn” flakes |
| LLDPE | 0.918 – 0.940 | Agglomerated granules |
| HDPE | 0.94 – 0.97 | Hard, compacted chunks |
| PP (Woven) | 0.90 – 0.91 | Semi-fused flakes |
The Impact of a 50:1 Compression Ratio
The compression ratio measures how effectively a system reduces volume. While entry-level machines often stall at 20:1, Rumtoo’s advanced engineering achieves ratios up to 50:1. This drastic reduction is essential for:
- Container Optimization: Loading 5 to 10 times more weight into every shipment.
- Energy Savings: Removing moisture mechanically is significantly cheaper than using thermal drying ovens.
- Increased Extrusion Yield: Densified material melts more uniformly, reducing energy spikes in the extruder.
Engineering for Performance
When evaluating an industrial-grade plastic film squeezer and densifier, ensure the system features a high-torque gearbox and a screw design tailored for abrasive post-consumer waste. Rumtoo systems are engineered to handle high contamination levels while maintaining the <3% moisture threshold required for premium pellet production.
Conclusion
Optimizing Plastic Film Squeezer density and compression ratios is the foundation of a profitable recycling business. By transforming wet, bulky waste into high-density feedstock, you ensure that your integrated recycling lines run at peak efficiency with the lowest possible environmental footprint.
