Abstract
A packaging machine includes: a conveying machine that conveys a package blank for a package; a lid-side magnetizing roller that is supported so as to be able to come into contact with the lid-side magnetic region of the package blank, and so as to be rotatable when coming into contact, and has a permanent magnet which magnetizes a magnetic material of the lid-side magnetic region; and a body-side magnetizing roller that is supported so as to be able to come into contact with the body-side magnetic region of the package blank, and so as to be rotatable when coming into contact, and has a permanent magnet for magnetizing a magnetic material of the body-side magnetic region so as to form a predetermined magnetic distribution corresponding to a magnetic distribution in the lid-side magnetic region formed by the lid-side magnetizing roller.
