FAQ

● Is the preferred solution for mid to high end coffee packaging, with stability, freshness, and high aesthetics as its core, balancing functionality and brand communication needs.

Core advantage: How to "lock fresh" coffee with one-way exhaust valve ☕ ️

‌ ✅ Release carbon dioxide and block oxygen from entering

Applicable scenario: Deep roasted coffee beans will produce a large amount of CO ₂ due to high temperature, and the valve will automatically discharge the gas to avoid packaging bursting.

Preservation principle: The valve only allows one-way discharge of internal gas, and external oxygen cannot flow back, reducing oxidation rate (extending shelf life by more than 30%).

‌ ✅ Balance internal and external air pressure to prevent flavor loss

Technical details: The valve is made of food grade PP/PE material, with precise control of the air pressure threshold (± 1.5kPa) to prevent the volatilization of coffee oil and aromatic substances.

‌ ✅ Adapt to the dynamic requirements of different baking degrees

FAQ

Q: Why is the bottom designed as a flat bottom? Is it easy to stand up? ‌

A： Flat bottom enhances support, allowing for upright placement without the need for additional brackets; Some brands have added anti slip patterns at the bottom to prevent tipping.

Q: How long can coffee be stored after opening? ‌

A： It is recommended to use up the packaging without adding a one-way exhaust valve within one month; The packaging containing a one-way valve can be extended for 2-3 months, but it needs to be stored in a cool place away from light (preferably 15-25 ℃).

Q: Can empty bags be reused? ‌

A： It can be used as a storage bag after cleaning (such as travel packaging), but high-temperature disinfection may damage the inner structure, and it is not recommended to come into contact with food for a long time.

Q: How to choose different brands with significant differences in packaging capacity? ‌

A： Recommended size for household use is 200-500g (avoid frequent opening); For commercial use, a large capacity of 1kg or more can be selected, but it needs to be used in conjunction with a packaging tank.

Q: Does bloating in coffee bags indicate spoilage? ‌

A： Mild bloating is normal exhaust (especially for deep roasted coffee). If accompanied by an acidic odor or severe bulging, it may have been damp or oxidized, and it is recommended to stop consumption.
