The back film 42 is provided with an opening cut line 49 along both ends of the opening film 48 to form an opening photographic piece 50, and the entire surface film above the upper side seal portion 47 is a photographic piece. 51 are formed.

Since the above-described conventional packaging bag 41 is configured as described above, the opening shooting piece 50 and the shooting piece 51 are taken, the opening shooting piece 50 is pulled downward, and the opening By cutting the back film 42 wide along both ends of the film 48, the sand switch can be taken out with one touch.

However, the packaging bag 41 of the embodiment shown in FIGS. 8 and 9 has a disadvantage that the opening is too wide when pulled by a strong force, and the sandwich spills out more frequently than the conventional packaging bag. What happened. That is, the opening tape 48 is not always cut open along both edges of the opening tape 48. If the opening tape is opened with a strong force, the opening cutting to be formed along the edge 52 of the opening tape 48 as shown in FIG. The line 53 may spread away from the edge 52 and be cut open to the side of the sandwich package.

In the present specification, by forming the opening sticking portion 30 at least in the vicinity of each of the edges 19a, 19b from the upper side seal portion 4 to the bottom side portion 7, the reason is that the opening film piece is used. As long as the back film 2 can be cut open along the outer edges of the sticking portions near the respective edges 19a and 19b from the upper side seal portion 4 to the bottom side portion 9, each of the opening film pieces 9 can be cut. This means that the band-shaped sticking portion 30 may be formed only near the edges 19a, 19b, and that the entire surface of the opening film piece 9 may be stuck to the back film 2.

In the present invention, as shown in FIG. 2, a part of the opening film piece 9 constitutes a part of the opening shooting piece 11 (the opening shooting piece 11 will be described later). Is preferred. With such a configuration, the opening shooting piece 11 and the opening film piece 9 are integrated, so that the opening shooting piece 11 is pulled downward, so that the opening sticking portion 30 is opened. The back film 2 can be easily cut open along the outer edge.

From the viewpoint of taking out the food, the length from the upper side seal portion 4 to the lower end of the opening film piece 9 is preferably about the same as the height of the triangular food. However, the opening film piece 9 may be provided from the top side seal part 4 to the bottom side part 7.

The opening film piece used in the present invention is preferably as wide as the opening film piece 9 shown in FIG. Specifically, the lateral length of the opening film piece 9 is preferably 20% or more, more preferably 40% or more, and more preferably 50% or more of the longitudinal length of the upper side seal portion 4. The above is more preferred. If the length of the opening film piece 9 is less than 20% of the length of the upper side sealing portion 4, simply opening along the edge of the opening sticking portion 30 allows one-touch picking of food such as a sandwich. It may not be possible to pull out.

The lateral length of the opening film piece 9 refers to the length of the opening film piece 9 in the vertical direction with respect to the vertical direction. Further, the length in the longitudinal direction of the upper side seal portion 4 is a length from the outside of the side side seal portion 5 to the outside of the side side seal portion 6. When the length of the upper seal portion 4 in the longitudinal direction is different in the direction perpendicular to the longitudinal direction, the length of the longest portion is set to the length of the upper seal portion 4.

[0035] The belt-shaped protective body in the present invention is provided on the outside edge of each of the opening sticking portions from the upper side seal portion toward the bottom portion, and on the outside edge of each of the opening sticking portions. It is provided by forming a belt-like protective sticking part in parallel. With this configuration, for example, as shown in FIG. 1, even if the unsealing cut line 20 attempts to spread away from the edge of the unsealing sticking portion, it is blocked by the protective sticking portion 17. The back film 2 is not opened more than the space provided with the protective adhesive portions, so that it is possible to easily prevent food such as a sandwich from spilling out. The belt-shaped protective body is preferably provided inside the bag from the viewpoint of aesthetics and function, but may be provided outside the bag as long as the back film 2 can be prevented from being cut too wide. .

However, in the present specification, a belt-shaped protective adhesive portion is formed in parallel with an outer edge from the upper seal portion to the bottom edge portion of each opening adhesive portion. As long as it can be prevented from being cut apart and spread apart from the edge of the sticking part for opening, it is meant to include substantially parallel cases such as slanting. Further, the outer edge from the upper side seal portion to the bottom side portion of the opening sticking portion is defined by each end of the opening sticking portion from the upper side seal portion to the bottom portion of the opening film piece. When the opening sticking portion is formed only in the vicinity of the edge, it means the outer edge of the inner edge and the outer edge of the opening sticking portion. Therefore, when the entire surface of the opening film is adhered to the back film, there is no inner edge.

As a preferred embodiment of the above-mentioned band-shaped protective body and the protective sticking portion in the present invention, for example, as shown in FIGS. Adhering by forming the protective adhering portion 17 can be mentioned.

When the opening shooting piece 11 is pulled downward with one hand and the other hand, the opening film piece 9 is formed to be wide, so that it is cut open wide along both ends thereof. When the opening film piece 9 is peeled off, the upper half of the sandwich is exposed to the outside, so that the sandwich can be immediately taken out and eaten.

Since the food packaging bag 1 of the present invention is provided with the protective adhesive portions 17, 25, it is pulled too strongly and cut away from both ends of the opening adhesive portions 30, 26. Even if it does, it will not be cut open wider than the interval where the protective adhesive parts 17, 25 are provided.

In the above description of the food packaging bag, the case where the opening film piece is wide is mainly described, but this is particularly effective when the present invention is used to open the food packaging bag widely. That is, the opening film piece may be narrow from the viewpoint of preventing the food packaging bag from being excessively opened and broken at the time of opening.

As described above, the food packaging bag of the present invention must not be too wide, even if it is configured so that it can be easily cut into a wide width enough to take out food. Since it is not available, it can be suitably used for packaging food products such as sandwiches, particularly triangular sandwiches, triangular sandwich-shaped rice balls, and triangular castellas.

It is preferably at least 20% of the length in the longitudinal direction. With such a configuration, food such as a sandwich can be taken out with a single touch without dropping the food too much to the side portion.

If a configuration is adopted in which the protective tape is attached to the inside of the bag body by forming a protective tape as the belt-like protective body, the food packaging bag of the present invention can be easily manufactured. At the same time, it is possible to reliably prevent the slit from being too wide open.

As the belt-shaped protective body, a band-shaped non-sticking portion, an inner sticking portion sandwiching the band-shaped non-sticking portion from both sides near the both end edges of the wide film piece from the upper sealing portion to the bottom portion, and a belt-like protecting member. The wide film piece is adhered to one of the plastic films by forming the outer sticking part of the outer side, and a cutting line is formed from above to below on the wide film piece constituting the strip-shaped non-sticking part. By adopting a configuration in which the belt-shaped protective body is separated, the food packaging bag of the present invention can be easily manufactured, and it can be surely prevented from being too wide open.

If a configuration is adopted in which the two plastic films have a trapezoidal shape and a part of the opening film piece is a part of the opening shooting piece, it is possible to wrap a triangular food without waste. .

The position where each of the two ends of the opening taking piece is provided is near the upper side of the upper side seal portion, and the intersection of the opening sticking portion and the upper side seal portion, and the position adjacent to the intersection. By adopting a configuration that is between the sticking part for protection and the intersection of the upper seal part, the plastic film can be easily and reliably cut open.
