The present invention relates to a method and an apparatus for a tray arrangement for a series of continuously linked trays. The trays are adapted to be stacked by a twisting mechanism and by a series of curved side guards which twist and bend the links connecting the trays in order to arrange the trays into the proper configuration. The trays are then unstacked by another series of curved side guards and twisting mechanism and then each tray is in turn moved to a filling station where filling material is dispensed therein. The filled tray is then moved to a lid closing station where the attached flipped open lid of the tray is closed atop the tray. The tray is then pulled by a side grasping pull flange to a position where an overhead piston driven mechanism seals the lid and cuts the link, separating the tray from the nested of the trays.
