ABSTRACT:
Portable sealing apparatus for the sealing of plastic coated paperboard cartons includes a frame and a fixed jaw mounted thereto. A single movable jaw is utilized to seal top portions of the carton by fusing of a polyethylene coating thereon. Guide means enable manual placement of the carton with the sealable portions thereon disposed between the fixed and movable jaw. Proper selection of pressure, time and controlled heating of the jaws enables the carton to remain adjacent the fixed jaw before, during and after the sealing thereof, without subsequent remelting of the polyethylene coating and opening of the seal for a period of time.
