Abstract: A method and the relative device for packaging ordered groups of products in a carton comprises the following stages: feeding one carton at a time, in the form of a flat pre-folded blank, to a loading table and simultaneous opening of the blank, by means, to form a tubular carton body with two opposite openings one on either side, two first pairs of smaller flaps and two second pairs of larger flaps or lids; folding of the two pairs of smaller flaps, by first means, during carton feed in a preset direction, so as to form a first partial closure of the openings; and closing of the carton body, by second means, by simultaneous folding of the pair of lids towards the two openings so as to obtain a closed package.
