One of the biggest advantages of the Maren ProPak 2R350 Two-Ram Baler is its ability to process an extremely wide range of commodities with consistent bale weights and density. This makes it a favorite among recycling centers, printers, packaging plants, and MRFs that handle multiple material streams.
High-Density Bale Capabilities
According to Maren's published bale weight data, the 2R350 produces impressive bale weights across common recyclables, including:
- OCC: 1,700 lbs
- Mixed paper: 1,700 lbs
- Magazines: 2,000 lbs
- Aluminum cans: 1,100 lbs
- Aluminum extrusions: 1,400 lbs
- Tin cans: 2,200 lbs
- HDPE: 1,500 lbs
- PET: 1,300 lbs
- Copper (non-insulated wire): 6,000 lbs
- #1 Copper: 4,000 lbs
These weights position the ProPak 2R350 as a top performer in the two-ram class.
Why It Handles So Many Materials Well
1. Wide 57.5” x 80” feed opening
This allows large volumes of material—OCC, metals, rigid plastics, and more—to enter the chamber efficiently.
2. High ram force (353,429 lbs)
This force, combined with 207 psi ram face pressure, ensures dense bales even with springy or lightweight materials like PET or HDPE.
3. Smart material recipes
Operators can store parameters for each commodity:
- Pressure
- Dwell time
- Wire settings
- Photo-eye selection
- Bale dimensions
Switching between commodities becomes both cleaner and faster.
4. Bale separation door
This feature virtually eliminates cross-contamination between materials and allows for easy clean-out when switching commodities.
Perfect for Multi-Material Facilities
If your facility handles more than one commodity, this baler excels in:
- Fast changeovers
- Consistent bale density
- High throughput
- Reduced wire usage
- Cleaner material transitions
The ProPak 2R350 is engineered to run continuously across different material types with minimal operator intervention.
