A coffee one way degassing valve, a key component, plays a crucial role in preserving coffee freshness. It is installed on coffee bags, whether in aluminum foil, kraft paper, or stand-up pouches, using valve applicator machine at approximately 200°C. This high-temperature installation method not only effectively prevents the degassing valve from falling off and leaking, but also protects fresh coffee from contamination by external moisture. A high-quality one way degassing valve provides one way degassing, effectively preventing backflow of air while blocking moisture, ensuring a high degree of airtightness and stable degassing performance. When choosing a suitable degassing valve, consider the HZV6 & HZV6F valve models. These valves automatically expel carbon dioxide released from roasted coffee beans out of the bag, preventing outside air from entering, thereby ensuring the beans remain dry and fragrant. This design also effectively prevents bag expansion caused by carbon dioxide accumulation and oxidation contamination of the inner packaging.
