PURPOSE: A resin composition for extrusion is provided to reduce the use of polypropylene-based resins which are harmful for the environment by comprising starch and paper. CONSTITUTION: A resin composition for extrusion comprises 30-50 weight% of a silane compound-grafted polypropylene-based resin grafted with a silane compound, 10-40 weight% of starch, and 10-40 weight% of paper. The silane compound-grafted polypropylene-based resin is obtained by polymerizing a modified polypropylene resin which consists of 97.00-99.89 weight% of a propylene-ethylene, propylene-1 butene copolymer, or a propylene-ethylene-1-butene terpolymer; 0.1-2.0 weight% of a silane compound; and 0.01-1.00 weight% of a molecular weight controller.
