A Barcelona recycling plant faced €24,000 monthly penalties until switching to CE-certified balers. Their bale weight consistency improved from 68% to 96% compliance – proving certification matters more than raw power.
CE-certified horizontal balers maintain EN643 standard bale weights (630-680kg) through precision hydraulics (±1.8 PSI control) and real-time density algorithms, achieving 15-18% higher resale value compared to non-certified models. These systems automatically adjust for 12 types of cardboard variations and 6 common contaminants.
Discover how five critical parameters separate compliant from substandard equipment.
How Much Does a Standard Cardboard Bale Weigh?
A Dutch recycler lost €14,000 monthly by producing 590kg bales that missed EN643 requirements. Precision weight control transformed their profitability overnight.
Standard cardboard bales under CE certification must weigh 630-680kg with dimensions of 700x800x900mm (LxWxH). Modern balers use laser measurement systems achieving ±0.35% weight variance through 9-stage compression cycles and moisture sensors with 0.8% accuracy.

What Type of Cardboard Should Be Placed in the Baler?
A UK facility destroyed €38k hydraulic seals processing prohibited poly-coated boards. Material restrictions aren’t optional – they’re economically essential.
6 Approved Cardboard Types:
- Corrugated Fiberboard (OCC)
- Solid Bleached Sulfate (SBS)
- Uncoated Chipboard
- Molded Pulp Packaging
- Paper-based Composite Boards (≤8% polymer)
- Wax-Alternative Treated Boards (BioPE coated)
Contaminant Detection Economics
| Detection Method | Error Rate | Cost/Ton Saved | Penalty Avoidance |
|---|---|---|---|
| Manual Sorting | 12-18% | €3.20 | €9.40 |
| NIR Sensors | 1-1.8% | €0.85 | €16.70 |
| X-Ray Systems | 0.5-0.9% | €1.40 | €23.50 |
Contamination Protocols:
- X-Ray identifies metal staples (≥1mm resolution)
- Air jets remove plastics at 8 bar pressure
- Auto pressure reduction for wet layers
- RFID tags log contamination events
Cost Analysis:
- Polish facility saved €71k/year using X-Ray detection
- ROI: 2.3 years on €162k system investment
How Much Force Does a Cardboard Baler Have?

Conclusion
CE-certified horizontal balers guarantee standard compliance through three pillars: adaptive force control (1,800-3,400 PSI), real-time contamination detection (≤0.9% errors), and automated weight calibration (±0.3% variance). Implement ISO 13849 controls and demand EN13042 certification for 19-27% ROI within 18 months. Always verify load cell calibration (Class M1) and hydraulic oil cleanliness (ISO 4406 16/14/11).
