ABSTRACT:
A packaging bag has a mouth which is shaped so that it can be opened by blowing air into the mouth. A stack of such bags are folded flatly and are sequentially opened for receiving articles. Each bag has a back wall with hooking holes provided for receiving a stacking hook. The front wall of each bag has a large notch which overlies the holes with clearance to permit easy raising of the front wall when air is used to open the mouth. The hooking holes are also formed so that they are easily torn when the bag is pulled off the hook in a direction away from the mouth. To this end, each hook hole has a sharp portion in the direction of the mouth.
