<P>PROBLEM TO BE SOLVED: To provide a packaging material capable of restraining rice-processed food, for example, from losing its shape in unsealing, and capable of suppressing tearing of sheet-like food. <P>SOLUTION: This packaging material comprises an outer film which is constituted in such a manner as to be dividable in the width direction, and an inner film which is superposed on the outer film via the sheet-like food and in which a rupture assisting means linearly elongated in the direction orthogonal to the width direction is formed. The inner film is characterized in that it is equipped with a center film portion in which the rupture assisting means is formed, a pair of expansion film portions which are continuously provided at both side ends of the center film portion and constituted in such a manner as to be expandable in the width direction, and a pair of side film portions which are extended out to the outside of the width-direction from a leading end of each of the expansion film parts. <P>COPYRIGHT: (C)2009,JPO&INPIT |
