Abstract: A food tray system comprising a food tray, a suitably sized tray liner with an elastic member placed over and around the top portions of the food tray. The elastic member tightens the tray liner to the shape and size of the food tray to prevent the tray liner from being pulled or moved by a child. After use, the tray liner is removed from the food tray by loosening the elastic member from the edges of the tray. The removed tray liner is gathered inwardly by the elastic means to form an integral, closed waste bag for the clean removal of debris from the food tray. The food tray system may also be a food travel tray system, which also includes at least one horizontal support bar that is placed under the legs of a child in an infant automobile seat or standard automobile seat when the tray is in use. The food tray system further includes a cover, which may be used as an activity table. The activity table may have a light system integrated therein to allow for use of the activity table in the dark.
