The seal S may not be used. By doing in this way, the seal | sticker S of the folding | turning part 211 and the one side film 211 can be made easier to peel rather than when the folding | returning part 211 and the superposition | polymerization part 212 are sealed.

  Further, the seal S between the surface 210a of the center film 210 and the one side film 221 has a sawtooth shape as shown in FIGS. 7 and 8 in addition to a straight shape as shown in FIGS. The seal may be easily peeled off. 7A is a sawtooth shape in which a large number of isosceles triangles are continued within the same width as the linear seal, and FIG. 7B is a diagram in which a large number of right triangles are continued within the same width as the linear seal. Sawtooth shape, FIG. 7C shows a sawtooth shape in which only the center protrudes in a triangular shape.

  8 (a) shows a zigzag sawtooth shape with a sharp top, FIG. 8 (b) shows a zigzag sawtooth shape with a round top, and FIG. 8 (c) shows another part of each top. It has a thinner zigzag sawtooth shape. However, the sawtooth shape of the seal S is not limited to these, and may be, for example, a sawtooth shape in which a plurality of triangles protrude. In any case, the sawtooth-shaped seal is in a state where a concentrated load acts on the top portion, and therefore peels off more easily than the linear seal.

  On the other hand, since the seal between the back surface 210b of the center film 210 and the other side film 222 does not peel off, the seal may be linear. In the inner film 200, the center film 210 and the side films 221 and 222 are integrated with a seal without a gap, so that the inner film 200 and the outer film 100 sandwich the laver 1, and the two films 200, When the periphery of 100 is sealed, a packaging material in which the seaweed 1 is completely sealed is formed.

  In addition, the packaging material is folded in two so that the inner film 200 is joined to the rice ball 2, and the three sides of the peripheral portion of the overlapping inner film 200 are sealed, so that the laver 1 is separated from the rice ball 2 and packaged. It becomes a packaging tool. By wrapping the packaging material in half, even if the rice ball 2 is gripped softly and softly, it will not lose its shape. Therefore, when packaging the rice ball 2 held firmly, the packaging material may be folded along the shape of the rice ball.

  In any case, in the inner film 200, the center film 210 and the side films 221 and 222 are integrated with no gap, and since no cut is made, the water of the rice ball 2 does not enter the laver 1 . Therefore, the seaweed 1 is packaged while maintaining the crispy state.

  And in order to open, first, the outer film 100 is parted with the cut tape 101, and both corners on the bottom side of the packaging tool are pulled in the opposite directions. Then, the seal S between the surface 210a having the easy peel property of the center film 210 and the inner side portion 221b of the one side film 221 is peeled off. At this time, since the folded portion 211 of the center film 210 is pulled toward the other side film 222, the seal S is easily peeled off. Further, when the seal S has a sawtooth shape, the seal S is more easily peeled off.

  On the other hand, the back surface 210b of the center film 210 that does not have an easy peel property and the inner side portion 222b of the other side film 222 are not peeled off. Therefore, the inner film 200 is separated between the center film 210 and the one side film 221, and the one side film 221 is pulled out from between the rice ball 2 and the seaweed 1, and the center film 210 and the other side film. 222 is pulled out in the opposite direction from between the rice ball 2 and the seaweed 1 while being in one piece. Then, the laver 1 in a crispy state can be eaten in a state of wrapping the rice balls 2.

  As shown in FIG. 2, when the side films 221 and 222 are provided with folded pieces 221a and 222a, when the side films 221 and 222 are pulled out in the opposite direction upon opening, the side films 221 are provided. , 222 fold back edges of the rice balls 2 move on the surface of the rice ball 2, and the folded pieces 221 a, 222 a do not rub the rice ball 2, so that the rice ball 2 is not easily broken.

[Embodiment 2]
Next, a second embodiment of the packaging material according to the present invention will be described with reference to FIGS. However, portions corresponding to those in the first embodiment will be described with the same reference numerals.

  In the inner film 200 of this packaging material, both side portions of the center film 210 are not folded back, the surface 210a of one side portion 213 is joined to the surface of the side film 221 on the side of the rice ball 2, and the back surface of the other side portion 214. 210b is joined to the back surface of the other side film 222 on the laver 1 side. Therefore, the middle part of the center film 210 is sandwiched between the inner edges of the side films 221 and 222.

  For example, the side films 221 and 222 shown in FIGS. 9 and 10 are provided with folded portions 221c and 222c whose inner edges are folded back to the rice ball 2 side. The surface 210a of one side 213 of the center film 210 is joined to the folded portion 221c of one side film 221, and the back surface 210b of the other side 214 of the center film 210 is intermediate to the folded portion 222c of the other side film 222. It joins with the superposition | polymerization part 222d provided continuously between these parts, and each is sealed over the full length.

  Then, one side 213 of the center film 210 is sealed with a surface 210a (shown by a thick line in FIG. 10) having an easy peel property joined to the folded portion 221c of the one side film 221. As a result, when one of the side films 221 is pulled, the folded portion 221c is rolled up, and the seal S is easily peeled off.

  In addition, as shown to Fig.10 (a), the one side part 213 of the center film 210 and the one side film 221 are the surface 210a of the one side part 213, and the folding | returning part 221c of one side film 221. The overlapping portion 221d provided continuously between the folded portion 221c and the intermediate portion may be sealed, and as shown in FIG. 10B, the folded portion 221c of one side film 221 The overlapping part 221d may not be sealed, and only the one side part 213 of the center film 210 and the folded part 221c of the one side film 221 may be sealed. The inner film 200 shown in FIG. 10B can be more easily separated from the center film 210 and the one side film 221 than the inner film 200 shown in FIG.

  The seal S may be linear as shown in FIG. 9 or may be sealed in a sawtooth shape as shown in FIG. 7 or FIG. In any case, in the portion to be sealed S, three films of the center film 210, the folded portion 221c of one side film 221 and the overlapping portion 221d are overlapped.

  And since the seal | sticker S does not peel from the other side film 222 and the back surface 210b which does not have easy peel property of the other side part 214 of the center film 210, the folding | turning part 222c is provided in the other side film 222. It is not always necessary to provide it. However, by providing the folded portion 222 c on the other side film 222, the portions where the both side portions 213 and 214 of the center film 210 are joined to the side films 221 and 222 are overlapped with each other. In the state in which the original fabric 200G is wound in a roll shape as shown in FIG. 3, it is possible to prevent the occurrence of winding deviation without uneven thickness.

  Moreover, both the folding | returning parts 221c and 222c are folded by the rice ball 2 side, Therefore The productivity which manufactures the raw fabric 200G of the inner film 200 can be improved. Therefore, if the original film 200G of the inner film 200 is only wound in a roll shape without uneven thickness, the folded portion 222c of the other side film 222 is formed of one side film 221 as shown in FIG. The folded piece 221a may be folded back to the nori 1 side in the opposite direction.

  In addition, in the inner film 200 shown in FIGS. 12 and 13, a column film 223 that is folded in half is joined to one side film 221 and is sealed S over the entire length. The inner film 200 is arranged such that one side 213 of the surface 210 a having the easy peel property of the center film 210 and the folded portion 221 c of the one side film 221 are positioned at the center of the rice ball 2. . Therefore, the other side portion 214 of the back surface 210b of the center film 210 that does not have an easy peel property and the folded portion 222c of the other side film 222 are arranged eccentrically. Therefore, by sticking the pillar film 223 to one side film 221, the one side film 221 can be reinforced and balanced.

  Therefore, the distance between the one side 213 and the other side 214 of the center film 210 and the distance between the one side 213 of the center film 210 and the pillar film 223 are made the same. Then, the three films overlap each other at the portion where the side portions 213 and 214 of the center film 210 and the folded portions 221c and 222c and the overlapping portions 221d and 222d of the side films 221 and 222 are joined. Therefore, by folding the pillar film 223 in half, the three films overlap each other at the portion where the pillar film 223 and the one side film 221 are joined. The original film 200G of the inner film 200 is shown in FIG. As shown in Fig. 4, avoid uneven thickness when wound into a roll.

  Moreover, the folding | returning part 221c, 222c of each side film 221,222 can be efficiently produced by folding on the same side, for example, the rice ball 2 side, as shown in FIG.12 and FIG.13. However, the folded portions 221c and 222c of the side films 221 and 222 may be folded to the opposite side as shown in FIG. Even in this case, the surface 210a of one side 213 of the center film 210 and the folded portion 221c of one side film 221 are joined, and the back surface 210b and the other side of the other side 214 of the center film 210 are joined. The folded portion 222c of the film 222 is joined, and the seal S is performed over the entire length.

  In the inner film 200 in the second embodiment as described above, the center film 210 and the side films 221 and 222 are sealed and integrated without a gap, and no cut is made. Therefore, the inner film 200 and the outer film 100 sandwich the nori 1 and the periphery is sealed S, thereby forming a packaging material in which the nori 1 is sealed. This packaging material also becomes a packaging tool by being folded in half or packaging the rice ball 2 along the shape of the rice ball 2.

  Since the inner film 200 with the pillar film 223 sealed is provided with three overlapping portions of the three films, the rice ball 2 that is softly gripped is wrapped in a guarded state. The

  When opening the packaging tool, first, the outer film 100 is divided by the cut tape 101, and both ends on the bottom side of the packaging tool are pulled in opposite directions. Then, the surface 210a of the one side part 213 of the center film 210 and the seal S of the one side film 221 are peeled off. On one side film 221, the folded portion 221c is rolled up, and the seal S is easily peeled off. However, the other side portion 214 of the center film 210 and the other side film 222 are maintained in an integrated state without the seal S being peeled off.

  And one side film 221, the other side film 222, and the center film 210 are pulled out in the opposite direction, and the laver 1 in the crispy state can eat in the state which wraps a rice ball. In addition, since the inner film 200 with the pillar film 223 sealed is separated from the center of the rice ball 2, the rice ball 2 is further prevented from breaking.
