Therefore, in the present invention, the above problems are solved and the outer film 1 is not torn during packaging,
Moreover, it is an object of the present invention to provide a packaging material for rice balls in which the mouth of the opening operation piece 5 is not opened.

[0010]

Therefore, in the present invention, a pair of inner films 2 and 2 are formed on the outer edges 1a and 1a on the long side of the outer film 1 having a rectangular tearing direction in which the tearing direction is the longitudinal direction. One side is joined, the opposite sides 2a, 2a of the inner films 2, 2 are overlapped with each other at approximately the center in the width direction of the outer film 1, and the sheet-shaped food product is further placed between the outer film 1 and the inner films 2, 2. 6 is a packing material for rice balls sandwiching 6, and a pair of cuts 4 and 4 parallel to the tearing direction are formed in the outer edge portion on the short side of the outer film 1 to form an opening operation piece 5, and the inner portion thereof is A packaging material for rice balls adhered with an adhesive 3 capable of peeling off.

The adhesive 3 is preferably a low temperature heat-welding adhesive.

[0012]

In the packaging material for rice balls of the present invention, the inner portions of the cuts 4 and 4 formed on the short side are adhered with the adhesive 3, so that when the overlapping ear portions of the packaging material are folded back, Even if the outer film 1 is pulled in the width direction, it does not tear from the cut lines 4 and 4.

Further, since the inner portion of the unsealing operation piece 5 formed by making the cuts 4 and 4 is adhered with the adhesive 3, the opening of the unsealing operation piece 5 is not opened.

Since the adhesive 3 is an adhesive capable of peeling off, the opening operation piece 5 can be easily opened by pulling.

If the adhesive 3 is a low temperature heat-welding adhesive, the sheet-shaped food 6 will not be deteriorated by heat.

[0016]

Embodiments of the packaging material for rice balls of the present invention will be described below with reference to the drawings shown as embodiments.

In FIG. 1, reference numeral 1 is a rectangular outer film made of a film having a tearing direction, and the tearing direction is the longitudinal direction.
