In various embodiments of the present invention, trays with mechanical separation features are provided that reduce the adhesion between adjacent trays in a stack of at least partially nested trays or other plastic products. The separation features formed in the trays are strategically located to reduce contact between one tray's bottom surface from the top surface of the tray beneath it. In various embodiments, this is accomplished by employing a plurality of different tray designs, e.g., “A design” and “B design.” The different tray designs have substantially the same size and contour except for the location of the separation features. To prevent adhesion between the trays when stacked, the different tray designs are alternated when stacked (e.g., A design, B design, A design, B design) and the separation features reduce the nesting depth of adjacent trays.
