Tightly sealed bracket.

One-way valve

The design of the one-way degassing valve allows pressure inside the package to escape while preventing air from entering. Because freshly roasted coffee beans release carbon dioxide, the one-way degassing valve allows roasters to immediately package their product without worrying about the coffee bag bursting.

Resealable zipper

The sealing groove uses a unique concave-convex technology for a tight fit. The zipper can be opened and closed repeatedly, with strong sealing performance, and will not automatically open due to product compression even when the bag is full.

TAG:

It features a one-way exhaust function that prevents gas backflow and water vapor, ensuring high airtightness and stable exhaust performance.
