[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a food wrapping material for packaging food that is prepared by wrapping nigiri rice with sheet-like food such as laver when it is opened.
[0002]
[Prior art]
Conventionally, as a food wrapping material that can be eaten by wrapping sheet food such as seaweed with rice balls at the time of opening, accommodation between the outer film and the inner film consisting of the left part and the right part where the inner ends overlap each other There is one containing a sheet-like food in the part (see Patent Document 1).
[0003]
This type of food packaging material is made up of a transparent synthetic resin film, so that the printed sheet food, rice balls, and outer film can be seen as they are, and the viewing angle. Depending on the film, the film reflects light well, so that the high-quality feeling is not felt.
[0004]
Therefore, there has been a demand for a food packaging material that can be packaged so that a higher-class feeling can be felt.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0011]
The food packaging material of the present invention is a bag-shaped food packaging material in which a sheet-like food 5 wound around rice balls 4 is accommodated in an accommodating portion 3 between an outer film 1 and an inner film 2, and the outer film 1 is a surface. It has a surface layer portion 6 made of Japanese paper having a heat sealant layer 15 on the side, and utilizing the fact that this surface layer portion 6 has heat sealability, an overlapping portion 17 when packaging the rice balls 4, It is assumed that it is point-sealed by heat welding.
[0012]
1 is a perspective view of a food packaging material according to an embodiment of the present invention, FIG. 2 is a perspective view of an exploded state thereof, FIG. 3 is a cross-sectional view of an outer film 1, and FIG. FIG. 5 is a perspective view showing a state of wrapping the rice balls 4 with the food packaging material, and FIG. 6 is a view of the packaged food made by wrapping the rice balls 4 with the food packaging material. A perspective view, FIG. 7 is a perspective view as seen from the front side, and FIG. 8 is an explanatory view showing a state in which the rice balls 4 in a state of being wound around the sheet-like food 5 are taken out from the food packaging material.
[0013]
This food packaging material is comprised from the outer film 1, the inner film 2, and the sheet-like food 5 as shown in FIG. 1, FIG. The outer film 1 and the inner film 2 have a substantially rectangular shape with the same size, and as shown, the peripheral edge portions 7 are sealed by heat welding or the like.
[0014]
As shown in FIG. 3, the outer film 1 includes an outer film base 8 and a surface layer portion 6. The outer film base 8 is a transparent film made of a synthetic resin such as OPP (stretched polypropylene) and can be printed with appropriate characters and patterns 9.
[0015]
Two cut tapes 12 are attached to the outer film base 8 across a pair of sides (short sides) 10 and 11 facing each other at the center on the back side. , 11 is provided with cuts 13 on both sides of the cut tape 12 to form an opening operation piece 14. When the opening operation piece 14 at the edge of the side 10 is pulled, the outer film 1 is torn up to the opposite side 11 so that the outer film 1 can be divided into left and right.
[0016]
Furthermore, the outer film 1 has the surface layer part 6 on the outer film base | substrate 8, and this surface layer part 6 shall have heat-sealing property. In this embodiment, the surface layer portion 6 is made of translucent Japanese paper and has a heat sealant layer 15 on the surface side thereof. As the surface layer portion 6, for example, Japanese paper having an appropriate thickness that is white and in which raw material fibers are entangled in some places to form a pattern can be used. The heat sealant layer 15 can be made of a polyolefin-based thermoplastic resin.
[0017]
The surface layer portion 6 has the same size and the same shape as the outer film substrate 8 and covers the entire outer film substrate 8. However, even if it does not cover the entire outer film substrate 8, a point seal described later is performed. A part of the outer film base 8 such as a part may be covered.
[0018]
An adhesive layer 16 is interposed between the outer film base 8 and the surface layer portion 6, and both are bonded to each other by an adhesive method such as dry lamination. The dry laminating may be either a solvent method in which an adhesive is diluted with an organic solvent, applied to one of the outer film base 8 and the surface layer portion 6, dried and then pressure-bonded to the other, or a non-solvent method not using an organic solvent.
[0019]
The inner film 2 can be made of an appropriate material such as a synthetic resin similar to the outer film substrate 8. As shown in the drawing, the inner film 2 is composed of two films of a left part 2a and a right part 2b, and the left part 2a and the right part 2b are overlapped with each other by about 1 to 2 cm at the center. Like that.
[0020]
The outer film 1 and the inner film 2 have a region that is not sealed inside the peripheral edge portion 7, and this portion serves as a housing portion 3 that houses the sheet-like food 5.
[0021]
The sheet-like food 5 is laver or bonito or kelp formed in a sheet form with gelatin, and is appropriately selected and used. The storage operation of the sheet-like food 5 in the storage unit 3 may be either a manual method or a method of automatically inserting it by a machine.
[0022]
In order to wrap the rice balls 4 with this food wrapping material, the inner film 2 is placed face up as shown in FIG. 4, and the rice balls 4 are placed on the inner film 2 of the sheet-like food 5. The rice balls 4 are formed in a triangular shape.
[0023]
Next, as shown in FIG. 5, the food packaging material is bent so that the side 10 side where the opening operation piece 14 is provided and the side 11 side facing this are aligned, and along the rice balls 4, the rice balls 4 are Further, as shown in FIG. 6, the end portions are overlapped on the back side, and the overlapped portion 17 is point-sealed by thermal welding and fastened. Since the surface layer portion 6 of the outer film 1 of the food packaging material has heat sealability, point sealing by heat welding is possible in this way.
[0024]
The rice balls 4 wrapped in the food packaging material can be sold as a packaged food at a store such as a convenience store. The packaged food using this food packaging material is covered with the translucent surface layer portion 6 of the outer film 1, and the print 9 of the outer film substrate 8 or the sheet-like food is placed under the pattern of the surface layer portion 6. It can be seen through in a slightly faint state, has little reflection of light, and has a high-class feel.
[0025]
To open the food packaging material, the opening operation piece 14 is pinched with a finger and pulled. The outer film 1 is torn from one side where the opening operation piece 14 is provided to the other side opposite to the side. When the outer film 1 is torn to the end, the outer film 1 is divided into two parts at the center, so that the left part 2a of the inner film 2 can be obtained by pulling each divided part outward. The right part 2b is separated and the rice ball 4 is exposed in a state covered with the sheet-like food 5.
[0026]
In addition, the packaged food using the food packaging material of the present invention is not limited to the rice ball wrapped with the triangular nigiri rice 4, but with a suitable shape such as a round bar-shaped hand-rolled sushi or a substantially cone-shaped hand-rolled sushi. can do. The nigiri rice 4 can be a sandwich with a cutlet serving as an ingredient at the center, sushi rice, mixed rice, cooked rice, or the like.
[0027]
In addition, food packaging materials made of conventional synthetic resin films may be incinerated, but this food packaging material is incinerated by using paper such as Japanese paper as the surface layer 6. Since the surface layer portion 6 burns well together with the outer film base 8 and the inner film 2 made of synthetic resin, it can be safely incinerated. Moreover, the consumer can conveniently dispose of the opened food packaging material as burning garbage. The amount of the paper surface layer 6 is preferably 51% or more of the weight of the food packaging material.
[0028]
【The invention's effect】
The food packaging material and packaged food according to the present invention have the above-described configuration, and when the rice ball 4 is packaged using the food packaging material and the packaged food, a sense of quality can be felt from the conventional one.
