PROBLEM TO BE SOLVED: To provide a packaging bag designed such that projecting parts are formed on the respective un-sealing lines of the surface film and rear film so as to be displaced one from the other when unsealed, thereby making it easy to grip the projecting parts with fingers, thus facilitating opening of the mouth.SOLUTION: A packaging bag 100 is formed by superposing a surface film 1 and a rear film 2 and the perimeter edges of the superposed surface film and rear film are sealed. The surface film and rear film are respectively provided with a surface-side projecting easy-to-cut line 7 of upward projecting shape and a rear-side projecting easy-to-cut line 8 such that they substantially coincide in a vertical direction and are displaced sidewise one from the other, the cutting lines being used to guide cutting for opening so as to provide a grip part for opening the mouth after opening. The projecting part of the surface-side projecting easy-to-cut line and the projecting part of the rear-side projecting easy-to-cut line are respectively provided with embossed recognition marks 10, which can be recognized by touching.SELECTED DRAWING: Figure 1 |
