PURPOSE:To tear off easily by hand by a method wherein a polypropylene roll sheet which forms a container body of a container for round mirror-shaped rice-cake is made of polypropylene filled with a prescribed amount of inorganic filler. CONSTITUTION:Sheet-shaped matter which forms a container body 3 of a container for round mirror-shaped rice-case 1 is made of a compound of 100 pts.wt. of polypropylene and 40 to 150, preferably 60 to 145 pts.wt. of inorganic filler. As the inorganic filler, magnesium silicate is preferable. Considering that the weight of the rice-cake to be contained in the container body 3 is usually 160g to 8kg, the thickness of the sheet for this container body 3 is preferably 0.2 to 1.5mm. The container 1 thus obtained can be easily torn off by hand. |
