Flat Type vs. Gusseted Type Hemming: Engineering for Specific Needs
The debate between Flat Type and Gusseted Type hemming in PP Woven Bags boils down to application requirements. Let’s dissect both methods through practical engineering lenses.
Flat Type Hemming: When Simplicity Meets Efficiency
Common in 65% of global Poly Fabric sacks, this method features:
- Construction: Single 15-20mm fold secured with 8-10mm hot air weld
- Strengths:
- 12% faster production on Starlinger RX 8.1 looms
- 3% material savings critical for cost-sensitive markets
- 98% jam-free performance in automated systems
Ideal For:
- Cement packing (50kg-75kg ASTM C91 specs)
- Animal feed (HACCP-certified facilities)
- Resin pellets (FDA-compliant designs)
Gusseted Type Hemming: Engineering for Volume
Accounting for 35% of industrial demand, this method uses:
- Construction: 50-150mm tri-fold gussets with 12-15mm double stitching
- Strengths:
- 40% volume expansion (1.2m³ vs. 0.85m³)
- 25% better pallet stability in transit
- Superior performance with irregular cargo shapes
Ideal For:
- Chemical powders (REACH-compliant solutions)
- Construction aggregates (ASTM D4321 testing)
- Bulk foodstuffs (biodegradable additives)
