Abstract (en)
[origin: EP3957575A1] To provide a packaging bag that is hardly opened erroneously, can be easily opened, and can simply make an unused article to be packaged held and packaged in the packaging bag.The problem is solved by a packaging bag that is a gusset packaging bag including: a main unit section having a front surface, a back surface, and both side surfaces connecting the front surface and the back surface to each other, the main unit section storing an article to be packaged; and a handle section formed on a top side of the main unit section by overlapping the front surface and the back surface with each other, in which at least one of the front surface and the back surface of the main unit section has an opening forming portion, and the opening forming portion includes: a base point portion formed in a region located above a position corresponding to an uppermost portion of the article to be packaged that is stored in the main unit section and below the handle section; a pair of widening perforated portions having a gradually widening separation distance in a side surface direction from the base point portion toward a bottom side opposite to the top side; and a pair of extending perforated portions extending from the widening perforated portions in a top-bottom direction.
