<p>In a method for packing foodstuffs in a packaging under a preservative gas, first the foodstuff will be placed into a tray (19), then within a vacuum room a foil (25) will be sealed along the circumferential of the tray. After that a preservative gas (37, 39) will be injected in the tray via a hollow needle (35) which will be pierced through the foil. At last, the tray will be closed off. This can be done by dividing the tray in a main tray (19) and an auxiliary tray (21) which trays are connected to each other via a bridge (23). The needle (35) will be pierced through the foil (25) at the auxiliary tray (21). After injection the foil (25) between the main tray (19) and the auxiliary tray (21) will be sealed to the bridge (23). Eventually, after this, the auxiliary tray (21) can be removed from the main tray (19). With this method, in theory, it is possible to obtain one packaging with an unlimited number of trays with different gas atmospheres.</p> |
