Abstract
A packaged food article of improved appearance and stackability comprises an unpressurized, imperforate container having an opening, wherein the container is fabricated from a material having a low gas permeability. A quantity of gas releasing food stuff, such as an active cultured dairy product, is disposed within and partially fills the container, while defining a headspace volume which is not filled with the food stuff A peelable flexible seal membrane overlays and seals the opening. An initial headspace gas is enriched with the gas released from the food stuff, with the initial headspace gas being adapted to permeate the packaging material at a rate greater than both the rate in which gas is released from the food stuff within the container and the rate in which air permeates into the container, thereby avoiding outward bowing of the flexible seal during the shelf life of the packaged food article.
