A packaging machine is equipped with: a conveyor for conveying a package blank for a package so that, in the package blank, at least a first blank section related to a lid-side magnetic region and a second blank section relating to a package body-side magnetic region are in a prescribed unfolded state; a lid-side magnetizing roller, which is supported so as to allow contact with the lid-side magnetic regions of the package blanks that are being conveyed in the prescribed unfolded state and, when in contact with same, is supported to allow rotation, the lid-side magnetizing roller having a permanent magnet for magnetizing the magnetic material of said lid-side magnetic regions; and a package body-side magnetizing roller, which is supported so as to allow contact with the package body-side magnetic regions of the package blanks that are being conveyed in the prescribed unfolded state and, when in contact with same, is supported to allow rotation, the package body-side magnetizing roller having a permanent magnet for magnetizing the magnetic material of said package body-side magnetic regions so as to form a prescribed magnetic distribution that corresponds to the magnetic distribution in the lid-side magnetic regions formed by the lid-side magnetizing roller. |
