Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a packaging sheet for encapsulated foods used for packaging so-called encapsulated foods such as nigiri rice, nigiri sushi, sushi rolls, sandwiches, various kinds of confectionery or hamburg steak. Is.

[0002]

2. Description of the Related Art Conventionally, there is known a packaging sheet 100 for packaging a rice ball R0 which is a kind of encapsulated food as shown in FIG. This packaging sheet 100 is shown in FIG.
As shown in FIG. 3, an outer film 110 formed of a synthetic resin thin transparent film having a rectangular shape in a developed state with each corner cut out, and an outer film 110 laminated on the outer film 110. And an inner film 120 made of the same material as the above.

The outer film 110 has a cut tape 111 attached to the inner surface side (upper surface side of FIG. 7A) at the center position in the width direction and extending over the entire length in the longitudinal direction. Further, a pair of cuts 112 are provided on both sides of the cut tape 111 at one edge on the shorter side of the outer film 110, and thereby a gripping piece 113 that can be gripped with a finger is formed between the cuts 112.

The inner film 120 has a gripping piece 113.
Is formed by a pair of widthwise unilaterally split inner films 121 and 122 (a left unilaterally split inner film 121 and a right unilaterally split inner film 122) having overlapping portions 123 that are superposed on each other along the cut tape 111 at the portions corresponding to. .

Then, the inner film 120 consisting of the half-split inner films 121, 122 is laminated on the inner surface side of the outer film 110, leaving the gripping piece 113, and these edges are annularly welded to form a welded portion 130 ( By forming a stippled image, a packaging sheet 100 as shown in FIG. 7A can be obtained.

[0006] With the sheet-like seaweed 140 inserted into the packaging sheet 100 through the gap in the overlapping portion 123 between the left half-split inner film 121 and the right half-split inner film 122 of the packaging sheet 100, the inner film 1
At the center position on the 20 side, as shown by the chain double-dashed line in FIG.
Bend both ends of 0 in the longitudinal direction and wrap the rice ball R0,
By stopping the spot welding process, as shown in (b) of FIG. 7, the packaged food R1 with the sheet-like seaweed 140 in which the rice ball R0 is packaged with the packaging sheet 100 is completed.

According to such packaged food R1, the gripping piece 11
7 is pulled and the holding piece 113 is pulled in the direction of the arrow in FIG. 7B, the outer film 110 is divided by the strong cut tape 111 so that the notch 112 extends, As a result, the rice ball R0 is in a state of being wrapped by the halved outer film 110 and the originally halved half-split inner films 121, 122. Then, when the outer film 110 and the half-split inner films 121 and 122 that are divided into two are opened to the left and right and divided, the sheet-like seaweed 140 remains and the rice ball R0 covered with seaweed is obtained.

[0008]

By the way, in the conventional packaging sheet 100 as described above, the outer film 1 is used.
Since a transparent synthetic resin is used as the material 10, the encapsulated food inside (in the example of FIG. 7, sheet-like seaweed 14
0) is seen through as it is, and there is a disadvantage that the packaged food R1 looks cheesy.

In order to eliminate such inconvenience, it is conceivable to use a material such as Japanese paper as the outer film 110. By doing so, the rice ball R0 wrapped with the packaging sheet cannot be seen directly from the outside, but since the paper material such as Japanese paper is strong, in order to enable the one-touch unpacking using the cut tape 111, It is essential to form perforations along the cut tape 111. However, if the outer film 110 is provided with perforations, the sheet-like seaweed N can be moistened due to the ingress and egress of moisture from the inside of the package,
New problems such as unsanitary conditions caused by the invasion of microorganisms are raised.

The present invention has been made in order to solve the above-mentioned problems, and can impart a high-grade feeling to packaged foods, effectively suppress alteration of the encapsulated foods, and further divide the packaged foods. It is an object of the present invention to provide a packaging sheet for easily wrapped foods.

[0011]

The invention according to claim 1 is
A packaging sheet for encapsulated food used for packaging encapsulated food, comprising a sheet body for packaging encapsulated food with a breaking means, the sheet body, a paper material It is formed by a pair of paper-like sheet bodies including and a strip-shaped film made of synthetic resin interposed between the pair of paper-like sheet bodies, and the breaking means is integrally laminated on the film so as to extend in the longitudinal direction of the film. It is characterized by being.

In the present invention, the breaking means is for assisting the division of the sheet body. For example, a tensile stress is applied to the sheet body in a strip shape across the sheet body on the back side of the sheet body. It is common to use a larger synthetic resin tape. Due to the presence of the breaking means, by pulling the breaking means toward the outside in a state in which the wrapped food is wrapped by the sheet body, both side portions of the breaking means in the sheet body are broken and rolled into a band shape, and thus the sheet body It is possible to easily take out the encapsulated food that has been packaged by dividing.

In the present invention, the concept of a paper-like sheet body containing a paper material includes natural paper itself such as Japanese paper,
Not only the so-called synthetic paper itself made of a cellulose derivative such as acetyl cellulose is included, but also such natural paper or synthetic paper laminated with a usual synthetic resin film is included.

According to the present invention, the encapsulated food packaged by the sheet body is covered with an opaque paper-like sheet on most of its outer surface. Not only is the inconvenience of seeing through the product unsightly and making the product look cheesy, it also adds a sense of luxury, which increases the commercial value of the packaged food.

Moreover, since a strip-shaped film is provided between the pair of paper-like sheet bodies and the breaking means is integrally laminated on the strip-shaped film, the breaking means can be pulled to the outside by pulling the breaking means to the outside. Because it is guided and divided,
The pair of paper-like sheet bodies is easily divided into right and left.

According to a second aspect of the present invention, in the first aspect of the present invention, the sheet body is laminated with an outer sheet body made of the paper-like sheet body, and the outer sheet body.
An inner sheet body made of synthetic resin that wraps the encapsulated food in a state where the inner surface side is in direct contact with the inner sheet body, and the inner sheet body is a pair of inner sheet pieces separated so that the facing edges overlap at the position of the breaking means. Each of the inner sheet pieces is formed by a peripheral edge portion except for the facing edge portion and is integrally connected to the peripheral edge portion of the outer sheet body.

According to the present invention, the encapsulated food is wrapped in the packaging sheet so as to be brought into contact with the inner sheet body, so that it is double-wrapped by the inner sheet body and the sheet body. In addition, it becomes hygienic in which the invasion of microorganisms into the packaging film is effectively suppressed, and the outside is covered with a transparent paper-like sheet body, which gives a high-class feeling and increases the commercial value.

Then, while the sheet-like food is loaded between the inner sheet body and the outer sheet body, the outer sheet body is divided by pulling operation of the breaking means, and thereafter, the divided pieces are separated left and right. As a result, the encapsulated food is removed from the packaging sheet while being wrapped in the sheet-shaped food.

The packaging sheet of the present invention may be used by packaging it with an enclosed food product interposed between the inner sheet body and the outer sheet body. When such a packaging method is adopted, the packaged food product may be displayed so that the outer sheet body is located on the upper side. By doing so, the outer sheet body can be made conspicuous, so that the high-grade feeling of the packaged food is not impaired.

The invention according to claim 3 is the invention according to claim 1 or 2.
In the invention described above, the paper-like sheet body is laminated on the first film made of a synthetic resin, which is an inner surface side, an intermediate sheet body made of a paper material laminated on the first film, and the intermediate sheet body. It is characterized in that it has a three-layer structure with a second film made of a synthetic resin on the outer surface side.

According to the present invention, the intermediate sheet body made of a paper material is closely sandwiched between the first film and the second film made of the synthetic resin, so that the wrapped foods are wrapped with each other by the packaging sheet. It is possible to perform a temporary fixing welding process on the overlapped portions, which facilitates the packaging process.

[0022]

1 is a partially cutaway perspective view showing a first embodiment of a packaging sheet 10 according to the present invention, and FIG. 2 is a sectional view taken along the line AA. The packaging sheet 10 of this embodiment is for the rice ball R0.

First, as shown in FIG. 1, the packaging sheet 10
Has an octagonal shape in which four corners of a rectangular shape are obliquely cut out in a plan view. The packaging sheet 10 is an outer sheet body 2 positioned on the outer surface side in a state of wrapping the rice ball R0.
0, the inner film (inner sheet body) 30 laminated on the inner surface side (upper side in FIG. 1) of the outer sheet body 20, and the outer side so as to extend in the longitudinal direction at the widthwise central portion of the outer sheet body 20. It has a basic structure including a cut tape (breaking means) 40 laminated on the inner surface side of the sheet body 20.

The outer sheet body 20 has a width dimension that is slightly narrower than 1/2 of the width dimension of the packaging sheet 10.
a, the right sheet body 20b, and the respective sheet bodies 20a, 20
The strip-shaped film 50 is interposed between the b.
Then, the band-shaped film 50 is used for the sheet bodies 20a and 20b.
The outer sheet body 20 is formed by performing welding or adhesion treatment in a state of being bridged between the inner surface sides (upper surface sides in FIGS. 1 and 2) of the facing edge portions.

Then, at both ends of the strip-shaped film 50,
A pair of widthwise cutting portions 24 are formed by cutting from the outer edge by a predetermined dimension, and a gripping piece 25 that can be picked by a finger is formed between the cutting portions 24.

In the present embodiment, each of the sheet bodies 20a and 20b has a first film 21 which is an inner side, and a predetermined coating treatment on the outer surface side (lower side of FIGS. 1 and 2) of the first film 21. An intermediate sheet body (paper-like sheet body) 22 laminated by
And a second film 23 laminated on the outer surface side by a coating process.

The above-mentioned first film 21 and second film 23
While the strip-shaped film 50 is formed of a thin film of a normal thermoplastic synthetic resin such as polyethylene or polypropylene, the intermediate sheet body 22 is a so-called rayon paper formed in a Japanese paper shape. On the front and back surfaces of the intermediate sheet body 22, a Japanese paper-like straining pattern is formed, and by seeing this straining pattern through the second film 23, the packaging sheet 10 becomes rich in quality. I have to.

The reason why the intermediate sheet body 22 is sandwiched between the first film 21 and the second film 23 made of a usual thermoplastic synthetic resin is as follows. That is, when the sushi rice R0 is wrapped with the packaging sheet 10, as shown in FIG. 3, the front and back sides of the packaging sheet 10 are overlapped with each other (as an overlapping aspect, the inner surface side of the outer sheet body 20 and the inner film 30 are overlapped with each other, Since the outer surface side of the outer sheet body 20 and the inner film 30 are overlapped with each other, it is necessary to perform a welding process on the overlapped portions in order to prevent the wrapping from unraveling in such an overlapped state. The first film 21 and the second film 23 made of a synthetic resin material that are easy to weld on the front and back of the intermediate sheet body 22 that is difficult to weld
This is because it is necessary to stack

The second film 23 has a matte treatment on its surface side and is made semitransparent by the matting treatment. As a result, the paste pattern on the surface of the intermediate sheet body 22 is visually recognized through the semi-transparent second film 23, which creates a vague feeling, which makes the packaging sheet 10 more luxurious. Become.

The cut tape 40 is formed of a predetermined synthetic resin material which is uniaxially stretched in the longitudinal direction, whereby the tensile stress in the longitudinal direction is made larger than the tensile stress in the width direction and is difficult to tear. Has become. The cut tape 40 is welded or adhered over the entire length in the longitudinal direction at the center position in the width direction on the inner surface side (the upper surface side in FIGS. 1 and 2) of the band-shaped film 50.

Therefore, by grasping the tab 25 together with the cut tape 40 with a finger and pulling it outward,
While the strip-shaped film 50 is guided by the cut tape 40, the portions corresponding to the opposite edge portions of the left and right sheet bodies 20a and 20b are broken, and the outer sheet body 20 is divided into the left and right sides.

The inner film 30 is composed of a pair of inner film pieces (inner sheet pieces) 30a formed on the left and right sides,
30b (the left inner film piece 30a and the right inner film piece 30b). The width dimension of each inner film piece 30a, 30b is set to be slightly wider than 1/2 of the width dimension of the outer sheet body 20, whereby each inner film piece 30a, 30b is set to the first film 21 of the outer sheet body 20. The overlapping portion 31 extending in the longitudinal direction is formed in the widthwise central portion in the state of being overlapped on the side.

Then, while the inner film 30 is laminated on the first film 21 side of the outer sheet body 20 provided with the cut tape 40 and the band-shaped film 50, the peripheral portions thereof are welded. As shown in FIGS. 1 and 2, the packaging sheet 10 having the weld zone 32 formed on the peripheral portion is formed. In the state where the packaging sheet 10 is formed, a storage space 33 having an opening in the overlapping portion 31 is formed between the outer sheet body 20 and the inner film 30, the periphery of which is closed by the welding zone 32. ing.

In the present embodiment, this storage space 33
Is loaded with sheet-like seaweed N as a sheet-like food. This sheet-shaped seaweed N is placed on the first film 21 in advance in the manufacturing process of the packaging sheet 10, and in this state, the welding zone 32 is formed so that it is loaded into the storage space 33. There is. However, instead of doing this, the overlapping portion 31 is opened after only the packaging sheet 10 is formed, and the sheet-shaped seaweed N is inserted into the storage space 33 from here.
May be inserted.

The above-mentioned first film 21 and second film 2
3, the inner film 30 and the strip film 50 are formed of a thermoplastic synthetic resin having a relatively low softening point. Examples of such thermoplastic synthetic resin include polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyamide (PA), polyvinylidene chloride (PVDC), or ethylene vinyl acetate prepared to have a predetermined softening point. A copolymer (EVA) or the like is preferably used.

As the intermediate sheet 22, a synthetic resin commonly referred to as rayon paper, which is made of so-called cellulose derivative such as acetyl cellulose, acetic acid / nitric acid cellulose, methyl cellulose, ethyl cellulose or carboxymethyl cellulose, is preferably used. In the manufacturing process of the intermediate sheet body 22 made of such a cellulose derivative, the intermediate sheet body 22 can be given a high-class feeling by being subjected to a predetermined treatment for imparting a strained pattern.

As the matte treatment, the second film 2 is used.
Sand blasting method of spraying sand on the surface of No. 3, etching matte method of etching the surface of the second film 23 with an alkali saponification liquid or organic solvent, matting agent coating method of coating the surface with a matting agent to form a matte, or second film A mat roll method or the like in which 23 is passed through a roll having a matte surface such as a satin finish or a paste pattern can be used.

In this embodiment, the mat roll method is adopted. Specifically, the raw material of the second film 23 in a molten state is supplied to the surface of the intermediate sheet body 22 which is moving in a stretched state through a predetermined supply roll, and is laminated on the surface of the intermediate sheet body 22. Before the coating layer having a uniform thickness is solidified, the matte pattern on the surface of the mud roll is transferred to the second film 23 by a pressing process by dipping the coating layer in a rotating mud roll.

FIG. 3 is a perspective view showing a state in which the rice ball R0 is wrapped by the packaging sheet 10. As shown in this figure, the packaged food R1 formed by packaging the rice ball R0 with the packaging sheet 10 has the second film 23 subjected to the mat treatment on the outermost side and the lower side thereof. Since there is the second film 23 in which a strained pattern like Japanese paper is formed, it is not unsightly as compared with the conventional packaging sheet 100 (FIG. 7) in which the contents are transparent, and is in a blurred state through the first film 21. It is graceful because the strained pattern of the intermediate sheet body 22 is visually recognized,
And it becomes rich in quality.

When the rice ball R0 is wrapped with the packaging sheet 10, the outer sheet body 20 that can be heat-welded is used.
Since there is a portion where the first film 21 and the second film 23 overlap with the inner film 30, the appropriate portions of these overlapping portions are spot-welded to each other. By doing this
The inconvenience of unwrapping the packaging sheet 10 in which the is packaged is avoided.

The left and right sheet bodies 20a, 20b are
As shown in FIG. 1, since the opposing edges are connected by the strip film 50 over the entire length in the lengthwise direction, the tab 25 formed on the end of the strip film 50 is pinched to form the cut tape 40. By pulling toward the outside, as shown by the chain double-dashed line in FIG. 3, both sides of the band-shaped film 50 are broken and disengaged from the outer sheet body 20, whereby the packaging sheet 10 is divided into left and right.

Then, by separating the left and right halves of the wrapping sheet 10 in opposite directions in the state where the wrapping sheet 10 is divided into the left and right parts, the two inner film pieces 3 are originally provided.
Left inner film piece 30 composed of 0a and 30b
The a and the right inner film piece 30b are also divided into the left and right, and the packaging sheet 10 is separated left and right, so that the rice ball R0 inside can be taken out.

FIG. 4 is a partially cutaway perspective view showing a second embodiment of the packaging sheet according to the present invention, and FIG.
It is a -B line sectional view. As shown in these drawings, the packaging sheet 11 of the second embodiment is intended for sandwiches, and is formed in a trapezoidal shape in which the left and right sides are symmetrical in plan view. The packaging sheet 11 includes an upper sheet body 60,
A lower film (lower sheet body) 70 of the same shape laminated on the lower surface side of the upper sheet body 60, and the upper sheet body 6
And a cut tape 40 similar to the above, which is laminated on the back surface side of 0. In addition, in the second embodiment, the strip film 50 employed in the first embodiment is not employed.

The upper sheet body 60 is composed of a left sheet body 60a and a right sheet body 60b which are divided into left and right parts at the central portion. Each of the sheet bodies 60a and 60b includes a first film 61 on the inner side (lower surface side in FIGS. 4 and 5), and an intermediate sheet body (paper-like sheet body) 62 laminated on the upper surface side of the first film 61. , And a second film 63 further laminated on the intermediate sheet body 62. And, while the first film 61 and the second film 63 are formed of the usual thermoplastic synthetic resin similar to the first and second films 21 and 23 of the above first embodiment, the intermediate sheet. The body 62 is made of rayon paper, which has the same texture pattern as Japanese paper on the front and back, similar to the intermediate sheet body 22 of the first embodiment.

The above-mentioned first film 61 is used for each sheet body 60.
The sheet bodies 60a and 60b are commonly provided over a and 60b, so that the sheet bodies 60a and 60b are connected to each other via the first film 61.

The lower film 70 is made of the same synthetic resin material as the inner film 30.
In the state where the lower film 70 is laminated on the lower surface side of the upper sheet body 60, the oblique side portion and the top side portion of the trapezoid are welded with a predetermined width dimension so that the peripheral welding band 71 is formed.
And a transverse welding zone 72 that crosses the upper sheet body 60 and the lower film 70 in the width direction is formed at a portion slightly inside from the top side position of the trapezoid,
The upper sheet body 60 and the lower film 70 are integrated by the peripheral welding zone 71 and the transverse welding zone 72.

In a state where the upper sheet body 60 and the lower film 70 are integrated with each other, a central portion in the width direction of the packaging sheet 11 extends over the entire length in the longitudinal direction formed by only the first film 61. A break zone 65 is provided.
A band-shaped film according to the present invention extending in the longitudinal direction is formed by a portion of the first film 61 that is widened to the left and right from the breakable band 65. Then, the cut tape 40 is welded or adhered over the entire length of the lower surface side of the rupture band 65, so that the upper sheet body 6 is formed.
It is assigned to 0.

The upper sheet body 60 and the lower film 7
Before 0 and 0 are integrated, the tip portion of the fractured band 65 (see FIG.
On the left side of), a pair of widthwise cuts 64 formed by cutting the cut tape 40 from the edge portion are provided, and the first film 61 between the cuts 64 forms a tab 66. There is. The tab 66 is for peeling the breakable band 65 from the upper sheet body 60.

In the packaging sheet 11 thus obtained, a storage space 73 for storing the sandwich is formed between the lower film 70 and the first film 61 of the upper sheet body 60, and the base A loading port 74 for loading the sandwich into the storage space 73 is formed between the upper sheet body 60 and the lower film 70 at the bottom of the shape.

In FIG. 6, the sandwich R2 is the packaging sheet 1
It is a perspective view which shows the state packaged by 1. As shown in this figure, the packaged food R3 obtained by packaging the sandwich R2 with the packaging sheet 11 has the upper sheet body 60 having a strained pattern such as Japanese paper in its upper half. It is extremely graceful in terms of overall balance, has a high-quality feeling with a texture, and is a transparent rupturable band 65 composed of the first film 61 extending in the longitudinal direction at the center of the inclined surface in the width direction. Since it is provided, the type and state of the sandwich R2 can be visually recognized through the rupturable band 65, and the packaging sheet 11 has a high-class feeling and convenience.

According to such a packaging sheet 11, a thin synthetic resin is formed over the entire length in the longitudinal direction at the center position in the width direction of the slope portion of the packaging sheet 11 in which the sandwich space R2 is loaded in the storage space 73 (FIG. 4). A breaking zone 65 made of the first film 61 is provided, and the breaking zone 6 is formed.
Since the cut tape 40 is integrally laminated on the back surface side of 5, the breakable band 65 is guided to the cut tape 40 by picking and pulling the tab 66 including the cut tape 40 toward the outside. Both side portions of the cut tape 40 are broken, and the inclined portion of the packaging sheet 11 is divided into right and left portions.

Then, in a state where the sloped portion of the packaging sheet 11 is divided into left and right parts, the divided portions are pinched with fingers and pulled apart from each other, whereby the remaining portions of the packaging sheet 11 are also broken. The sandwich R2 inside can be taken out.

The present invention is not limited to the above-mentioned embodiment, but also includes the following contents.

(1) In the above embodiment, the intermediate sheet members 22, 62 made of rayon paper are adopted, but the present invention is limited to the intermediate sheet members 22, 62 made of rayon paper. However, it may be made of a paper material itself such as Japanese paper.

(2) In the above-described first embodiment, the packaging sheet 10 is composed of the outer sheet body 20 and the inner film 30 in order to mount the dried sheet-like seaweed N, and the storage space 33 is provided therebetween. By forming the sheet-shaped seaweed N into the storage space 33, the moisture of the rice nigiri R0 is prevented from being transferred to the sheet-shaped seaweed N, but from the beginning, the seaweed was wrapped around the rice nigiri R0 and the seaweed became wet. In the case where the seaweed is in a state of being packed with wet type rice balls, the inner film 30 is not particularly necessary because the storage space 33 for storing the sheet-shaped seaweed N is not necessary, and the outer sheet body 20 is not necessary. The wrapping sheet may be composed of only one.

(3) In the above embodiment, the ordinary transparent synthetic resin films are used as the inner film 30 and the lower film 70, but instead of this, the inner film 30 (inner sheet body). The lower film 70 may be made of the same material as the outer sheet body 20. By doing so, the packaging sheet gives the impression that it is entirely made of Japanese paper, and the sense of quality of the packaged foods R1 and R3 can be further enhanced.

(4) In the above embodiment, the left and right sheet bodies 60a and 60b forming the upper sheet body 60 are formed.
Is divided into left and right over the entire length of the packaging sheet 11, but the present invention is not limited to the case where the respective sheet bodies 60a and 60b are divided into left and right as a whole, and the transverse welding zone 72 is used. The left and right intermediate sheet bodies 62 and the second film 63 may be bifurcated to each other on the leading end side via a bridge portion.

[0058]

According to the invention described in claim 1, the sheet body is substantially composed of a pair of paper-like sheet bodies containing a paper material and the paper-like sheet body interposed between the pair of paper-like sheet bodies. Since it is configured with a synthetic resin strip film having the same length dimension, the encapsulated food packaged by the sheet body,
Most of the outer surface is covered with an opaque paper-like sheet, and when the sheet body is entirely transparent, it is unsightly to see all the encapsulated food and the inconvenience that the product looks cheap is solved. Not only that, but on the contrary, a high-class feeling is imparted, which can increase the commercial value of the packaged food.

Moreover, since the strip-shaped film is interposed between the pair of paper-like sheet bodies and the breaking means is integrally laminated on the strip-shaped film, the breaking means can be pulled to the outside by being pulled outward. The pair of paper-like sheet members can be easily divided into right and left parts by being guided and broken.

According to the second aspect of the present invention, the encapsulated food is wrapped with the packaging sheet so as to be in contact with the inner sheet body so that the inner sheet body and the outer sheet body doubly. It becomes wrapped and becomes hygienic in which the invasion of microorganisms into the packaging film is effectively suppressed, and the outside is covered with a paper-like sheet body, giving a sense of quality and increasing the commercial value. You can

Then, while the sheet-shaped food is loaded between the inner sheet body and the sheet body, the outer sheet body is divided by the pulling operation of the breaking means, and then each of the broken pieces is separated left and right. The encapsulated food wrapped in the sheet food can be easily taken out from the packaging sheet.

According to the third aspect of the present invention, the paper-like sheet member is used as an intermediate sheet member, a synthetic resin first film laminated on the intermediate sheet member and serving as an inner surface, and the intermediate sheet member. Since it has a three-layer structure with a laminated second layer made of synthetic resin, which is the outer surface side, an intermediate sheet made of paper material should be closely sandwiched between the first film made of synthetic resin and the second film. This makes it possible to perform a temporary fixing welding process on the overlapping portions of the wrapped food wrapped with the packaging sheet, thus facilitating the packaging process.
