The containers can have a vented film membrane that seals an opening in the container, the film membrane having a vent opening that allows for a release of gas build up from within the container through the vent opening. Additionally, the outer package completely surrounds the multiple packages and further contains a one-way valve that allows for release of the gases accumulated within exit through the valve while preventing gases from entering through the valve and into the package.
