EXAMPLE A transparent polyester film was printed as a table material 1 and a transparent laminated film in which a linear low-density polyethylene was laminated as a heat-fusible layer on the printed surface was used. As the gusset film, a film having a paper atmosphere in which linear low-density polyethylene was laminated on thin paper was used. As the backing material 2, a film in which an oil-absorbing and heat-fusible polyethylene nonwoven fabric sheet was laminated on the back surface of the same film as the gusset film was used. Printing was applied only to Table Material 1. A gusset insertion bag having a width of the front material 1 and the back material 2 of 10 cm, a gusset insertion depth of 3 cm, and a film length of 20 cm was produced. Therefore, the fixed interval 22 is 4
cm. Since X was set to 4 in the production, the width of the front material 1 and the back material 2 was 40 cm, respectively, and printing only had to be performed on the film for the front material 1. Therefore, the printing cost was drastically reduced.
