Frequently Asked Questions
1. How does the one way valve work for coffee bags?
The one way valve allows CO2 (produced by freshly roasted coffee during degassing) to escape the bag, preventing bulging or bursting. At the same time, it blocks oxygen from entering, which would oxidize the coffee and ruin its flavor—keeping it fresh for longer.
2. Can we choose the position of the one way valve on the bag?
Yes! We can place the one way valve anywhere on the bag (top, side, or bottom) according to your design or functional needs. Most clients prefer the top corner for easy degassing and minimal impact on branding.
3. Are the one way valves food-safe and durable?
Absolutely! Our one way valves are made of food-grade plastic certified by FDA and SGS, non-toxic and odorless. They’re designed to remain functional for up to 12 months, ensuring long-term freshness preservation.
Do the bags still need to be sealed after adding the one way valve?
Yes! The one way valve only handles degassing and oxygen blocking. We recommend adding a zip lock or heat-sealable closure to the bag, so consumers can reseal it after opening—maintaining freshness for unused coffee.
5. Can we get samples to test the valve’s performance?
Yes! We offer custom samples with one way valves within 3-5 working days. You can test the valve’s degassing efficiency, bag airtightness, and overall quality before placing a bulk order. Sample fees are deductible from bulk payments.
