To guarantee the strength and durability of fiber drums, the following key measures are implemented during the manufacturing process:

1. High-Strength Material Selection

• Kraft paperboard (made from virgin or recycled pulp): Provides the foundational strength.
• Metal reinforcements: Such as galvanized steel rings for reinforcing the top and bottom.
• Liner materials (e.g., LLDPE plastic or aluminum foil): Enhance moisture resistance and chemical protection.

2. Structural Design and Manufacturing Process

• Multi-layer compression molding: High-temperature and high-pressure forming to improve compressive strength.
• Seam reinforcement: Stapled seams with steel banding for added durability.
• Square/rounded corner designs (e.g., Ro-Con drums): Optimize stacking stability and impact resistance.

3. Rigorous Testing Standards

• UN certification tests: Including drop tests (impact resistance), stacking tests (load-bearing capacity), and material consistency checks.
• Chinese national standard GB 12463: Requires waterproof testing and structural strength validation for rigid fiber drums.

4. Additional Protective Measures

• Moisture-proof treatments (aluminum foil coating or polyethylene lining): Prevent degradation in humid conditions.
• Customizable accessories (e.g., metal lids/ventilation systems): Adapt to different transportation environments.

5. Quality Control & Certifications

• Consistent production standards: Ensure uniform material specifications for each batch.
• Periodic recertification (e.g., every 5 years): Maintain compliance with international shipping regulations.

By integrating these measures—from material selection to testing—fiber drums achieve high strength and durability while remaining lightweight.
