(57) [Abstract] [Purpose] Crystallinity with improved workability, with improved transparency and image clarity, without the problem of stains on film forming rolls during extrusion molding and mold contamination during injection molding. A polyolefin composition is obtained. [Structure] Made of crystalline polyolefin and graphite fluoride, Fluorinated graphite is added to crystalline polyolefin from 0.1 to 10 00 wtppm, preferably 0.5-500 wtppm A crystalline polyolefin composition containing the same, a sheet and a stretched film comprising the same. |
