Case Study 2: Specialty Coffee Roaster — Extending Freshness Shelf Life by 60%
How Aritpack’s Custom 8-Side Seal Pouches with One-Way Degassing Valves Helped a Nordic Coffee Brand Scale Globally
Client Background
A Nordic specialty coffee roaster shipping 40,000+ bags/month to 18 countries. Their premium single-origin beans demanded packaging that preserved aroma and freshness during 4–6 week ocean freight.
The Challenge
- Existing stand-up pouches allowed oxygen ingress, causing staling within 3 weeks
- No degassing valve → freshly roasted beans built up CO₂, causing bag bloating and occasional ruptures
- Inconsistent foil barrier layers led to 3.2% product spoilage rate
- Brand needed premium shelf presence to justify $18/bag price point
Aritpack’s Solution
Custom 8-side seal flat bottom pouch with high-barrier laminate:
- Structure: PET(12μm) / AL(7μm) / PE(80μm) — oxygen transmission rate < 0.5 cc/m²·24h
- Integrated one-way degassing valve (GORE membrane) releases CO₂ while blocking oxygen
- Matte finish with spot UV accents on brand logo
- Resealable zipper for post-opening freshness
- Tin-tie closure option for 250g retail SKU
- Valve placement precision: ±1mm tolerance for consistent sealing

Client Testimonial
“The difference in cup quality after 6 weeks is night and day. Aritpack’s valve placement is so precise that we’ve never had a single leak in 500,000+ bags. Their team even helped us optimize the foil thickness to cut costs by 8% without sacrificing barrier performance.”
