ABSTRACT:
Several embodiments of a die for heat sealing a heat sealable carton having a gable shaped closure are disclosed. Each embodiment of the die includes a pair of opposed jaws. Each of the jaws has portions for providing a firm seal capable of keeping bacteria out of the carton, and other portions for selectively sealing non-critical areas of the carton to a lesser extent to make the carton easy to open. The lightly sealed areas are caused by a recessed area in at least one jaw; a protrusion associated with a recessed area provides a highly staked seal area. A method of packaging in gable top cartons is also disclosed.
