容された内容物である。FIG. 1 is a schematic perspective view showing a packaging bag 1 according to an embodiment in which the present invention is applied to a pillow bag, and FIG. 2 is a sectional view taken along the line II-II. The packaging bag 1 is composed of a laminate 2 containing an easy peel film in the innermost layer and a uniaxially stretched film in the middle layer.
It has. The back seal 4 is made wider than the conventional back seal, and seal portions 5 and 6 are formed at the front end and the upper and lower ends thereof, and the back seal is folded between the main body of the packaging bag and the back seal. A non-seal portion 8 is formed between the wire 7 and the seal portion 5. Further, an opening notch 9 for starting tearing is formed at one end of the non-seal portion 8. The laminate 2 constitutes the packaging bag 1 such that the stretching direction of the uniaxially stretched film is parallel to the back seal 4, that is, the direction of the arrow AA. In the figure, reference numeral 10 denotes the contents stored in the bag 1.

Easy peel film (40 μm), and the like. Here, DL is a dry laminate layer (urethane-based adhesive layer), and AC is an intercoat agent layer. In addition, examples of the easy peel film include “CMPS-007” of Tocelo Chemical Co., Ltd. and “9501A” of Toray Gosei Co., Ltd. Examples of the uniaxially stretched film include the above-mentioned OPE (for example, “Hybron” of Mitsui Toatsu Chemicals, Inc.) and CPP (for example,
Resin films such as "EMH" of Toyobo Co., Ltd.) can be used.

きく開くことができる。In the packaging bag 1 having the above configuration, by tearing the back seal 4 from the position of the opening notch 9, the back seal 4 is torn in the stretching direction of the uniaxially stretched film (as indicated by a two-dot chain line 11), and the back seal 4 is separated. Can be easily opened. At this time, since the unsealing portion is the back seal 4 outside the folding line 7, this portion has no contents, and
There is no problem that the contents are not easily caught and opened when opened, and there is no problem such as damage to the shape of the contents. Thereafter, as shown in FIG. 3, by pulling one of the opened portions, the seal portion formed by the easy peel film at the upper and lower ends can be easily peeled off, and the opened portion can be greatly opened.
