Our custom flat bottom coffee bag with valve is a specialty packaging solution tailored for coffee brands (exemplified by the Brewora-branded bag above). The core one-way degassing valve (the circular feature on the bag) solves a key pain point for fresh roasted coffee: it safely vents accumulated CO2 to prevent bag expansion, while creating an airtight seal to block external oxygen—locking in the coffee’s original aroma and flavor for 4+ weeks post-opening.
The flat bottom structure ensures the bag stands steadily on retail shelves (no leaning or tipping), and the resealable zip lock lets consumers re-seal the bag after each use. Our fully customizable printing supports brand logos, artistic graphics, and product details (like the modern, color-blocked design on this Brewora bag) to make your coffee line stand out in competitive markets.
- Degassing Valve: One-way design (vents CO2, blocks air) for coffee freshness preservation
- Sealing Feature: Resealable zip lock (top edge) for repeated freshness post-opening
- Printing & Branding: Full-color custom graphics + brand logo (high color accuracy for brand consistency)
