Abstract:
A resin composition for blow molding is provided, made by formulating 0 to 30 weight parts of an inorganic filler based on 100 weight parts of a resin composition having of: 20 to 95% by weight of polypropylene resin having a melting point evaluated by a differential scanning calorimeter (DSC) of 160° C. or higher, the polypropylene resin being formulated of a propylene-ethylene block copolymer having an ethylene content of 3 to 15% by weight; and 5 to 80% by weight of polyethylene resin having a melting point evaluated by a differential scanning calorimeter (DSC) of 130° C. or higher, and a tensile break strength is 250 Kg/cm3 or more at ambient temperature, and a tensile break elongation is 500% or more.
