The present invention discloses a high intensity ultrasonic treatment method and apparatus that is used in conjunction with an existing commercial dough or batter mixer to enhance the rheological, aeration and textural properties of the dough or batter. The cylinder assembly may have a cylinder body with a cylinder chamber therein, a gland member disposed within the cylinder chamber, and a rod member movably arranged within the cylinder chamber and a rod opening of the gland member. A foldover magnetic stripe panel provides additional thickness to a portion of the package typically read by a magnetic strip reader while allowing very thin side panels.
