The 84mm fermentation lid is designed with an integrated one way duckbill valve that automatically releases carbon dioxide generated during fermentation while preventing outside oxygen, dust, and contaminants from entering the mason jar. This helps create a stable anaerobic environment for safer and more effective food fermentation.
Designed for wide-mouth mason jars with an 84mm opening, this reusable silicone fermentation lid is ideal for homemade fermented foods such as pickles, kimchi, sauerkraut, and fermented vegetables. The one-way venting system helps reduce internal pressure buildup during active fermentation while maintaining reliable sealing performance.
Manufactured from premium food-grade silicone rubber, the fermentation lid is safe, non-toxic, odorless, and suitable for direct food contact applications. The silicone material offers excellent flexibility and durability, and it does not easily crack, deform, or absorb odors during repeated use.
The precision slit opening on the duckbill valve is processed using high-precision punching technology, ensuring stable quality, clean slit cutting, and consistent one-way venting performance. The valve provides excellent sealing capability while allowing fermentation gas to escape smoothly.
The silicone fermentation lid is durable, flexible, and easy to clean. It is dishwasher safe and reusable for long-term fermentation applications, helping reduce disposable plastic waste while improving convenience for home fermentation users.
The lid color can be customized according to Pantone color numbers to match different branding or packaging requirements. Hopewell specializes in precision silicone molding and custom food-grade silicone products, including fermentation lids, vent valves, and silicone sealing components for various fermentation and packaging applications.
