PROBLEM TO BE SOLVED: To provide a household wrapping film which has improved heat resistance, adhesion, pulling-out properties, and cutting properties. SOLUTION: The household wrapping film is a single layer film made by extrusion molding of a resin compound using a T die, which resin compound is a blend of a homo-polypropylene resin of 100 mass pts. with a melt index of 10-25 g/10 min, one or two or more types of resins of 3 to 15 mass pts. selected from petroleum resins, rosin, terpene resin, cumarone resin, cumarone-indene resin, and a derivative from those substances, and a monovalent- or polyhydric-alcohol-based ester of 0.5-10 mass pts. with a melting point of lower than 10°C. In addition, a nucleating agent may be added to the resin compound. It is preferable that the polyhydric-alcohol-based ester is a triglyceride, and that the household wrapping film is formed into a roll and is encased in a box having a cutting blade.
