Abstract
Disclosed are reclosable and stackable food trays formed from a single blank that are capable of being folded and glued on standard machinery. Embodiments of the invention include raised gussets that extend beyond the top edge of the side panels of the formed tray and beyond the top of the formed tray. In some embodiments, the raised gussets help prevent distortion in all dimensions and facilitate the stacking of multiple trays on top of one another such that the stacked trays cannot slide off the lower tray.
