Reference numerals 2 and 3 denote a pair of inner films having one side joined to the outer edge on the long side of the outer film 1, and the opposite sides of the inner films 2 and 3 at substantially the center in the width direction of the outer film 1. Are superimposed. Further, a pair of cuts parallel to the tearing direction are formed in a substantially central portion of the outer edge on the short side of the outer film 1 to form an opening operation piece 1a.

Reference numeral 4 denotes a belt-like film welded to the inner film 3, which forms sleeve portions 4a and 4b protruding from both ends in the longitudinal direction.

Reference numeral 5 denotes a sheet-like food sandwiched between the outer film 1 and the inner films 2 and 3, and is selected from, for example, laver, bonito flakes and kelp formed in a sheet shape with gelatin.

Numeral 6 is a bar-shaped food. In this embodiment, sushi rice with ingredients in the center is used, but it can be changed to another food.

In order to package the bar-shaped food 6 using the bar-shaped food packaging material, as shown in FIG. 3, the bar-shaped food 6 is placed on the band-shaped film 4 and both ends thereof are placed. After covering the band-shaped film 4 with the sleeves 4a and 4b, the outer periphery of the bar-shaped food 6 is covered with the outer film 1. And
The end of the outer film 1 is stopped with a sealing seal (not shown).

Then, the state shown in FIG. 4 is obtained, and the product is sold in this state. A state in which the band-shaped film 4 of the packaging material for a bar-shaped food according to the present invention is not described in JP-A-4-20252, JP-A-4-20252.
