Is Waterproof Feature Available for One-Way Degassing Valves?#degassing #waterproof #packagingbag #coffee-valve #coffee #freshness
This degassing valve can enable the carbon dioxide gas produced by roasted coffee beans or coffee powder within the packaging to be expelled, preventing the packaging from swelling or even rupturing due to gas accumulation. At the same time, it can prevent the entry of external oxygen, moisture, etc. into the packaging, thereby maintaining the freshness and aroma of the coffee and prolonging its shelf life.
