A method and an apparatus for realizing cartons for packing includes feeding a cardboard band (2) for packing along an advancement direction (A) which is parallel to the development direction of the cardboard band (2) and making a first score line (II) and a second score line (12) on the cardboard band (2), so as: to identify a central sector; a first lateral sector (4), and a second lateral sector (5). The method further includes identifying regions of band (8) on the carton (2), making on each region of band (8) at least a first cut (21), a second cut (22), a third cut (23) and a fourth cut (24) oriented transversally so that a first closing wing (49), a first reinforcing wing (51) a second reinforcing wing (52), a second closing wing (50), a third reinforcing wing (53) and a fourth reinforcing wing (54) are defined. The band of carton (2) is cut transversally so as to separate the regions of band (8) from one another, thus obtaining cartons (I) for packing.
