It is common to make hand-rolled sushi at
On the other hand, hand-rolled sushi made for business use is displayed and sold at convenience stores, supermarkets, food stores in department stores, sushi shops, and the like, with the outer periphery wrapped in a conical cylindrical shape with a square transparent plastic film. Often.

[0003]

However, according to the above-mentioned conventional hand-rolled sushi packaging film, the laver sheet is in contact with the sushi shari, and the laver sheet is exposed to the outside at the upper and lower portions. By doing so, the seaweed sheet is easy to absorb the moisture of the sushi shari and the outside air, so that it becomes sticky, the original scent of seaweed,
There is a problem that flavor and texture are significantly impaired. There is also a hygienic problem, such as the attachment of various bacteria in the air.

[0004]

The present invention has been made in view of the above-mentioned problems of the prior art, and is capable of preventing moisture absorption of a laver sheet, maintaining the original aroma, flavor and texture of the laver for a long period of time, as well as being hygienic. In addition, when the seaweed sheet is pulled out or rolled in the sushi shred with ingredients, the seaweed sheet is not torn, and the sushi shari does not lose its shape. An object of the present invention is to provide a hand-rolled sushi packaging film that can be formed quickly and a packaging method thereof.

[0005]

As a first means for achieving the above object, a hand-rolled sushi packaging film of the present invention has a rectangular outer film and an inner film accommodating a laver sheet, and The film is composed of a narrow fixing film and a wide release film, and the fixing film is fixed to one end of the exterior film by sealing three outer sides thereof, while the release film is formed of the exterior film. At the other end, it is fixed by sealing its three outer sides,
And one end of the non-sealing portion of the release film extends upward or downward from the fixed film, and the extended end is turned upward in the opposite direction to form a folded piece. It is characterized in that it is formed so as to overlap with one side.

Next, as a second means for achieving the above object, a method for packaging hand-rolled sushi of the present invention has a rectangular outer film and an inner film accommodating a laver sheet, and the inner film is narrow. Consists of a width fixing film and a wide release film, the fixing film is fixed to one end of the exterior film by sealing the three outer sides thereof, while the release film is attached to the other end of the exterior film. ,
One end of the non-sealed portion of the release film extends upward or downward from the fixed film, and the extended end portion is folded upward in the opposite direction. A method of packaging hand-rolled sushi using a packaging film formed so that the base thereof overlaps with one side of the non-sealed portion of the fixed film, wherein the base of the folded piece from the upper surface of the fixed film in the interior film It is characterized in that the sushi shari placed on the upper surface is wound in a substantially conical shape obliquely upward from a corner where two sides sealed by the exterior film of the fixed film crosses.

[0007]

The sushi shrimper with the ingredients is wound into a substantially conical shape by a packaging film comprising an exterior film and an interior film accommodating a laver sheet, and is packaged in a transparent packaging bag in this state and sold at a store. In the above packaging state,
First, the opening piece of the packaging bag is picked up, torn open, and the sushi shred with the ingredients wound on the inner packaging film is taken out.

Next, when the wrapping film is unwound and unfolded flat, the sushi shari with the substantially conical shape is inclined over the upper surface of the fixed film in the interior film and the upper surface of the base of the folded back piece of the release film. Placed on At this time, the tip of the folded piece protrudes in the opposite direction from the sushi shari with ingredients.

Next, when the tip of the folded piece is picked and pulled in the direction opposite to the shari for sushi containing ingredients, the release film is peeled off from the exterior film and the seal portion thereof. At this time, the sushi shari is formed in a substantially conical shape as described above, and the upper half of the large diameter is placed on the upper surface of the fixed film, and only the lower half of the small diameter is placed on the folded piece of the release film. The peeling film can be smoothly peeled off even if the sushi sushi is placed on the upper surface because of being placed and the sliding characteristics of the film.
