Valve Tutorial

The simple, yet ingenious One-Way Degassing Valve allows gas to exit a package without allowing air to get in.  The valve is essential for packaging fresh coffee.  It is also used to release air pressure from large bags (e.g. petfood, resin, agricultural products, etc.) to allow stable pallet stacks. 

The valve is a disc shaped device about the size of a quarter.  It is heat sealed to the inside of a flexible package. 

PBi’s One-Way Degassing Valve has high performance and its unique one-piece design allows it to use over 35% less plastic compared to other two-piece designs on the market.
