Where is the degassing valve placed, and can I customize its position?

Yes — valve placement is fully customizable. Most roasters choose back center or front upper corner, depending on branding layout and filling method. If you're using automated filling/sealing lines, we recommend confirming valve height for machine compatibility.

Can I use the coffee bag with valve immediately after roasting, or should I wait for degassing first?

You can package coffee immediately after roasting. The one-way valve will vent CO₂ naturally over time without risk of bag swelling or oxygen ingress. This shortens turnaround time, reduces storage costs, and preserves aromatics at peak.

Are valve bags compatible with sustainable materials like kraft paper or recyclable films?

Yes. We offer kraft/PLA compostable bags and recyclable mono-material PE bags with integrated valves. While compostable valves are more sensitive to heat and humidity, we’ll help you choose the best combination for your product, shelf life, and disposal requirements.

Stock coffee bags with Valve — Ready-to-Use packaging for roasters

FernPack’s stock coffee bags with valve provide a ready-to-use packaging option for roasters that need pre-installed one-way degassing valves without developing a fully custom bag. These bags are designed for roasted coffee beans and ground coffee where controlled CO₂ release is required.

The valve is integrated during bag production, allowing the finished bags to be used directly with labels, stickers, hot stamping, or other branding methods. This makes the stock format suitable for both emerging and established coffee brands that prefer a consistent packaging format across different products or SKUs.

FernPack offers stock valve bags in selected sizes and material structures, while custom production is available for specific bag shapes, dimensions, materials, valve positions, printing, or other packaging requirements.

For brands requiring a specific bag construction, the same one-way degassing valve can be integrated into different coffee bag formats. For example, our Flat bottom coffee bags can be produced with an integrated valve when a stable retail format and larger branding surface are required.
