ABSTRACT:
A method for packaging foodstuffs including a liquid constituent comprises filling a tray with the foodstuff while the tray is horizontal, applying a cover to the tray and sealing the cover to leave a small gap at the periphery of the tray. The tray is then tipped to bring the gap to the top of the resultant package and the package squeezed so that the liquid moves towards the gap to displace air from the package. Sealing is then completed. Apparatus to effect the method is also disclosed.
