Meat product package and packaging method with maintained atmosphere

摘要

A method includes sealing a meat product into a container. The method then includes releasing carbon dioxide gas from a source contained inside the container to maintain a carbon dioxide gas presence in the atmosphere within the container. Sufficient carbon dioxide gas is preferably maintained in the package along or together with one or more gasses to maintain at least a slight positive pressure in the container or package, that is, a pressure slightly above atmospheric pressure.
