ABSTRACT:
A process for forming an easy-opening arrangement for gable-top cartons is described. A tape is applied to the inside of the pouring spout in order to stiffen the panels, while reducing the force required to separate the thermoplastic seal. The tape is bonded to the thermoplastic surface layer of the carton by an adhesive. During the hot air heating of the carton top prior to sealing, the area where the tape is located is not exposed to the hot air. During closing of the sealing jaws, surfaces on the opposed faces of the sealing jaw urge the adhesive into the space above the edge of the pouring spout to form an impermeable seal. The location of the tape on the carton blank and the apparatus for heating and sealing the carton are also described.
