<p>The invention relates to a packaging container for the in particular gas- and/or liquid-tight reception of preferably liquid-exuding foodstuffs, such as meat (10), fish or the like. An open side of a tray can be sealed with a cover (12) in a gas- and/or liquid-tight manner, thus making it possible to manufacture in particular a MAP package. In addition, the walls of the tray (11) are configured as having at least two plies. According to the invention, an open-cell foam plastic inner ply (17) of a circumferential side wall (15) of the tray (11) is reduced at least in its thickness. In this manner, a minimum concentration of the modified gas is maintained in the packaging container over an extended period of time so that perishable foodstuffs can be stored over an extended period of time and still remain fresh.</p> |
