Frequently Asked Questions
1. What is the function of the degassing valve on the aluminum foil coffee bags?
The degassing valve automatically releases carbon dioxide produced by freshly roasted coffee beans during storage, preventing the bag from expanding or bursting. At the same time, it blocks oxygen from entering, which is crucial for maintaining coffee freshness and flavor.
2. How effective is the aluminum foil layer in preserving coffee freshness?
Aluminum foil provides a 100% barrier against oxygen, moisture, light and odors - the main factors that cause coffee to stale. Combined with the degassing valve, our bags can extend the shelf life of coffee by 6-12 months, preserving its original aroma and flavor.
Can the degassing valve be customized in terms of color or position?
Yes. We offer degassing valves in various colors (black, white, silver, etc.) to match your brand design. The valve can also be installed in different positions (top, side) according to your bag structure and aesthetic preferences.
Are the aluminum foil bags suitable for vacuum packaging coffee?
Yes. Our aluminum foil bags have excellent airtightness and can be used for vacuum packaging. For vacuum-sealed coffee bags, we can omit the degassing valve or install a special valve that works with vacuum packaging processes, depending on your specific needs.
How do you ensure the quality of the degassing valves?
We source degassing valves from trusted suppliers with international certifications. Each valve undergoes strict testing (air tightness, pressure resistance) before installation, and we conduct random sampling tests on finished bags to ensure the valves function properly throughout the product lifecycle.
