PROBLEM TO BE SOLVED: To obtain a master batch pellet in which a fine inorganic filler is densely packed. SOLUTION: This master batch pellet is obtained by packing an inorganic filler having 2-7μm average particle diameter whose surface is subjected to hydrophobicizing treatment in a packing amount of 200-900 pts.wt. based on 100 pts.wt. polyolefin-based resin into the polyolefin-based resin, and a ratio (M-MFR/B-MFR) of melt flow rate (M-MFR) of the polyolefin-based resin to melt flow rate (B-MFR) of diluting pellet used for dilution is >1 and <4. |
