Specialty Coffee & Artisan Tea

Specialty Coffee & Artisan Tea

Freshly roasted coffee beans emit up to 6 liters of CO2 per kilogram while demanding zero oxygen ingress to prevent aromatic oil degradation. We engineer 5-panel box pouches with degassing valves and high-barrier foil laminates.

Key Packaging Hurdles:
  • •Continuous CO2 outgassing without admitting atmospheric oxygen
  • •Essential roasted oil aroma protection over 18+ months
  • •Smooth pull-tab pocket zippers with tactile matte tactile finish
QINPACK Solution:
  • Pre-welded Wipf & Goglio one-way degassing valves
  • Multi-layer foil laminate (PET/AL/PE) with OTR < 0.05 cc/m²·day
  • Reinforced 4-corner seals supporting rigid brick shelf display

Technical FAQ

Frequently Asked Technical Questions

Freshly roasted whole beans emit up to 6 liters of carbon dioxide (CO2) per kilogram over several weeks. Without a degassing valve, hermetic bags swell and rupture. Without an ultra-high foil barrier (PET/AL/PE, OTR < 0.05 cc/m²·day), oxygen penetrates the pouch and oxidizes delicate roast oils within days, causing stale off-flavors.
