To provide a heat-sealable laminated polypropylene resin film having heat-sealing strength and sealability enough to package a heavy load and a package obtained by using the film.

The oriented polypropylene resin film is obtained from a laminate having at least three layers of a substrate layer which is obtained from a crystalline polypropylene resin and a propylene-α-olefin copolymer and has a melting point of 155°C or below, an intermediate layer, and a heat fusion layer of a melting point of 150°C or below. In the heat-sealable laminated polypropylene resin film, at least 5 wt.% of a resin used in the heat fusion layer is incorporated.
