One-Way Degassing Valves
A Brief History
The one-way degassing valve was originally developed for coffee. Coffee is unique, as it is the only food product that needs to be completely protected from oxygen (O2) while at the same time it gives off relatively large volumes of carbon dioxide (CO2). At one time it was impossible to package truly fresh, whole bean coffee because there was no package that could be sealed off completely from O2 while at the same time releasing the CO2 gas from the package.
The invention of the one-way coffee degassing valve and its incorporation into the flexible package changed all this. The valve is now an integral part of any package used to deliver truly, fresh whole bean coffee to the market. Now, many other applications have been found for the valve. These include deflating large bags during palletizing (e.g. up to 50 lbs. of pet food, resins, agricultural chemicals, etc.), medical applications and other pressure relief applications.
PBi patented degassing valves are available in two sizes and may be purchased in case quantities or via volume contracts. Our valves can run on most valve applicators and form, fill & seal machines on the market. Please call for price quote.
