Abstract
In the fabrication of a resistance heater for a carton for packaging a pizza, an aluminum metallized sheet is adhered to a paperboard panel, a generally U-shaped strip of arc-sprayed zinc is applied to three edge portions of the upwardly facing electrically conductive metal layer of the metallized sheet, the interconnecting portion of the U-shaped strip and the immediately underlying metal layer are severed, and the metal layer is severed along a line extending adjacent the same interconnecting portion to the side thereof enclosed by the U-shaped strip, so that each of the severed sections of the interconnecting portion serves as a terminal for a corresponding leg portion of the U-shaped strip comprising the electrodes for the intermediate region of the metallized sheet.
