Packed body production method

A packed body production method for producing a packed body by packing a layered body of cartons containing paper material, the packed body production method comprising:

• a first step in which the layered body is formed by winding a packing film spirally around the cartons containing paper material so as to match progress of stacking the cartons and insertion sections into which a fork unit of a forklift is inserted is formed at a predetermined position in the layered body;
• a second step in which after the layered body is laid sideways, the packing film is wound around a front surface, a rear surface, a top surface, and a bottom surface of the layered body so as to retain the layered body entirely and close a front opening and a rear opening of the insertion section;
• and
• a third step in which after the second step is carried out, the layered body is returned to its original state before the layered body being laid sideways, and a side opening of each of the insertion section is closed by winding the packing film around the top surface, the bottom surface, a right surface, and a left surface of the layered body, wherein
• in the first step, the cartons are stacked in such a manner that the insertion sections are formed at such a position as to enable the layered body to be lifted using the fork unit of the forklift, and
• in the third step, the packing film is wound around the layered body so as to generate such a fixation strength that the layered body does not collapse when the layered body is lifted using the fork unit of the forklift.
