  Specifically, when the container 20 or the bag-like body 30 is formed using a paper material, the paper material was absorbed depending on the environment (temperature, humidity, etc.) in which the package is placed. There is a risk of moisture being discharged into the package. On the other hand, since the container 20 and the bag-shaped body 30 are made of resin, moisture is not discharged from the container 20 or the bag-shaped body 30, so that the container 20 and the bag-shaped body 30 are accommodated between the outer sheet 3 and the inner sheet 2. It can suppress effectively that the sheet-like food X gets wet.

  Moreover, the moisture which invades between the outer sheet 3 and the inner sheet 2 easily enters from the non-seal parts 1b formed at both ends in the longitudinal direction of the cooked rice packaging material 1 formed in a rectangular shape. For this reason, the container 20 is provided with a pair of first pair ridge wall portions 20d, 20d formed so as to face both ends in the longitudinal direction of the cooked rice packaging material 1, so that both ends in the longitudinal direction of the cooked rice packaging material 1 are provided. It is not exposed to the outside of the container 20. This prevents moisture from entering the space between the outer sheet 3 and the inner sheet 2 (that is, the storage space for the sheet-like food X) from the non-sealed portion 1b formed at the end of the cooked rice packaging material 1. It can be effectively suppressed.

  Moreover, since the strip | belt-shaped body 40 is wound around the container 20 so that the inner side of the opening part 20c of the said container 20 may be crossed to one direction, the cooked rice packaging material 1 will be discharged | emitted from this opening part 20c unintentionally. Can be prevented. Moreover, it can prevent that the cooked rice packaging material 1 deform | transforms by the fastening of the strip | belt-shaped body 40, and the sheet-like food X is damaged because the strip | belt-shaped body 40 is wound around the container 20 made of resin.
