To do. In addition, since the pair of heated seal bodies clamps the vicinity of the product at both ends of the packaging bag from above and below, it is possible to seal the air inside the bag while exhausting the air from the non-sealing part of the ear. It is possible to obtain a package having high tightness and close contact. Further, by bending the ear-like seal portion by the heated bending means, the ear-like seal portion can be easily bent, and the adhesive action of the adhesive and the heating action are combined to secure the seal portion to the bag end face. Lamination is done.

有効に実現し得る利点を有する。Furthermore, since the two ear-shaped seal portions of the packaging bag are bent in mutually different directions, when the predetermined number of packages are collected and packed in a box or other overwrapping, the end faces of the ear-shaped seal portions having different folding directions are different from each other. By assembling the packages so as to contact with each other, the aggregate of the packages becomes extremely compact, and the packing form is neat and stable. Therefore, there is an advantage that space saving and packaging cost reduction can be effectively realized in collective packaging.
