PROBLEM TO BE SOLVED: To provide a packaging bag capable of reducing the labor in selling commodities such as prepared foods, saving materials for sales, and reducing the sales cost. SOLUTION: The packaging bag is formed of a plastic film 5 with one end thereof opened. In its bottom part, a moisture-absorbing sheet 3 is laminated on a plastic film (a bottom film 2), and two-folded through the ridge fold in the width direction of the bag 1, and both ends thereof are heat-sealed 4 and 4 to a side edge of the bag 1. The moisture-absorbing sheet 3 and the bottom film 2 are expanded flat when storing commodities such as prepared foods, the prepared foods are received by an upper surface of the moisture-absorbing sheet 3 to provide the self-standing property to the bag 1.
