A polypropylene composite resin composition comprising:
- an amount of about 65% by weight to 85% by weight of a polypropylene resin;
- an amount of about 10% by weight to 20% by weight of microfibrillated cellulose;
- an amount of about 3% by weight to 13% by weight of an ethylene-octene elastomer;
- and
- an amount of about 1% by weight to 3% by weight of maleic anhydride-grafted polypropylene wherein the maleic anhydride-grafted polypropylene has a polar group gafted in an amount of 1 to 2 mol %,
- wherein all the % by weight are based on the total weight of the composition, wherein the microfibrillated cellulose is silylated, and
- wherein the composition does not comprise non-surface-modified microfibrillated cellulose.
