Title: PACKAGING BAG
Abstract:
Provided is a packaging bag which prevents an atmosphere-regulating agent from leaking out of a charging part of the packaging bag, for which reduction in cost and a simplified production process can be facilitated, and which can be used at a high temperature. This packaging bag has an upper edge portion that serves as a charging part in which an atmosphere-regulating agent is to be charged. The upper edge portion is formed such that ends of a packaging material on the front side and the rear side are positioned out of alignment with each other, and the relatively projecting end is folded over the outer side of the other end and is melt-bonded thereto.
