ABSTRACT:
The cutting edge for a sheet material dispensing carton has a plastic portion bonded to the paperboard material forming the carton. When the carton blank is formed, the plastic and paperboard are cut concurrently to form one edge of the blank. The paperboard and plastic material forming the teeth of the cutting edge are compressed to increase the sharpness of the cutting edge teeth.
