Abstract

A polyolefin resin composition comprising (A) an ethylene-based polyolefin having a density of 0.865 to 0.980 g/cm3 and MFR of 0.01 to 50 g/10 min, (B) a phosphorous compound, and (C) at least one heat stabilizer selected from the group consisting of a phenol-based heat stabilizer and a tocopherol-based heat stabilizer. The polyolefin resin composition has excellent heat resistance, moisture resistance and discoloration resistance, and also when used as a packaging material, does not impair the taste of contents to be packaged, such as flavor or odor, and therefore does not impair the taste of the contents.
