The Unseen Technology Demystifying the One-Way Valve in YOLO-PACK's Coffee Pouches

Technological innovation in coffee packaging often lies in the seemingly minor yet crucial details. The one-way degassing valve equipped on YOLO-PACK's ‌Coffee Valve Aluminum Stand-up Pouch 250g‌ is a high-tech product integrating materials science, fluid dynamics, and precision manufacturing. This valve, with a diameter of only 16mm, contains three functional layers internally: an outer 100-mesh stainless steel filter, a middle silicone diaphragm with precise opening pressure, and an inner layer with food-grade activated carbon to adsorb odors. This precise design ensures a dynamic balance of the internal packaging environment.

In actual operation, this valve demonstrates exceptional performance. According to a 180-day third-party, under standard conditions, the valve releases an average of 1.2-1.8 liters of CO2 per day while strictly maintaining oxygen ingress at an industry-leading level. This precise gas exchange mechanism allows coffee beans to "breathe" optimally inside the package, preventing both bag bulging from CO2 buildup and oxidative damage to the coffee's flavor.

YOLO-PACK's R&D team is meticulous in selecting valve materials. The silicone diaphragm uses a patented material from Wacker Chemie AG, maintaining stable mechanical性能 after 1 million open-close cycles. The valve housing uses polypropylene from Dow Chemical, ensuring elasticity remains unchanged within a temperature range of -20°C to 60°C. These material choices far exceed the basic requirements of a standard ‌food packaging bag‌, reflecting YOLO-PACK'spursuit of product quality.

Furthermore, the valve innovatively integrates humidity regulation functionality. This design detail effectively avoids quality fluctuations in coffee beans due to environmental humidity changes.

From a technical standards perspective, YOLO-PACK's one-way valve has passed major global food safety certifications like FDA and EU 10/2011. These strict quality control measures ensure that every ‌Coffee Valve Aluminum Stand-up Pouch 250g‌ leaving the production line provides the ideal storage environment for coffee. Through this kind of unseen technological innovation, YOLO-PACK is redefining the technical standards for the ‌food packaging bag‌.
